1). Mexicali, Baja California is a destination of contrasts that always surprises those who dare to explore it, a sample of this is Laguna Salada. Below 1300 m, a â¼200-m-thick interval of low-amplitude reflectors named here the âwhite unit,â overlies chaotic reflectors that we interpret as the basal conglomerate unit and granitic basement reported in well ELS-2 (see Fig. (B) Profile 4973. Over the years, I have been intrigued by the Laguna Salada (AKA Laguna Macuata) area of Mexico. Southward, the Cañón Rojo fault likely loses vertical displacement because it transfers part of the slip into the Chupamirtos fault. thesis], Centro de Investigación CientÃfica y de Educación Superior de Ensenada, Contrast between source parameters of M>5.5 earthquakes in northern Baja California and southern California, Sedimentation and deformation in a PlioceneâPleistocene transtensional supradetachment basin, Laguna Salada, north-west, México, Stratigraphic record of basin development within the San Andreas fault system: Late Cenozoic Fish within the San Andreas fault system: Late Cenozoic Fish CreekâVallecito basin, southern California, The San Andreas Fault System, California: U.S. Geological Survey Professional Paper 1515. Furthermore, Hough and Elliot (2004) reported a magnitude of 7.2 using a method based on the distance decay of modified Mercalli intensity (MMI) values for earthquakes in western North America (Fig. This page provides a complete overview of Laguna Salada, Baja California, Mexico region maps. La peligrosa Laguna Salada de Baja California 2 minutos Cuando uno piensa en la palabra “ laguna ”, se imagina un cuerpo de agua rodeado de tierra, escenario de hermosos paisajes. During the Pliocene, uplifting of the mountain ranges of Sierra Cucapah up to 700 m progressively isolated Laguna Salada from the delta plain and from the southwestern Salton depression (Axen et al., 2000; MartÃn-Barajas et al., 2001) (Figs. Translated from Spanish, the name lake means “Salt Lake”. This lithological change in well ELS-2 also corresponds to a change in seismic facies from low-amplitude, poorly contrasted seismic reflections of facies F3 to high-amplitude and continuous reflectors of facies F1. Seismic facies 1 and 2 predominate in the east and central portions of seismic profiles where the depocenter accumulates thicker sedimentary sequences. (B) Profile 5076-b. 2). 4A and 4B). Horizon 1 is the first laterally continuous reflector across the basin. 10.5 Ma volcanic deposits across the southern range front of Sierra Juárez (Mendoza-Borunda et al., 1998). The 9.7 km of extension (e.g., horizontal displacement) represents 53% of the basin width from the range front of Sierra Juárez in the west to the range front of Sierra El Mayor in the east and represents 24% of extension across the 40-km-wide zone of extension from Sierra El Mayor (285 m above mean sea level [amsl]) to the summit of Sierra Juárez (1596 m amsl). There, a major fault produces a vertical offset of more than 500 m along a horizontal distance of â¼2 km (cdp â¼6550â6750). Guadalupe Canyon Oasis is located southwest of the city of Mexicali in Northern Baja California, Mexico. Overall, the lower unit in the Cerro Colorado basin has similar lithological and chronostratigraphic characteristics to units of the Imperial Group in the southwestern Salton Trough (Winker and Kidwell, 1996; Dorsey et al., 2011). The modern course of the Colorado River appears in blue. Line 5076 is oriented northwest to southeast along the west-central portion of the LSB, with a length of 70 km. We first present the principal structural and stratigraphic characteristics to gain insight about the architecture and the amount of subsidence and extension principally in the southern LSB. The analysis and interpretation were conducted in five seismic-reflection profiles (Figs. Wells ELS-2 and ELS-3 reached the crystalline basement at 1.5 km and 0.75 km, respectively, whereas well ELS-1 located near the LSF cut the 2.4 km of sediments and did not reach the basement (Fig. 4A). The lake's shape vaguely resembles a rhombus. 5B) where the basement is clearly imaged at â¼1700 m near cdp 6250. 1), and only two major earthquakes have been previously located within the eastern basin marginâthe 1892, Mw > 7, and the 1934, Mw 6.5 (Ellsworth, 1990) (Fig. 8) although speculative implies that the Cañón Rojo fault would have a smaller vertical offset to the south. The stratigraphy in ELS wells provided stratigraphic and seismic velocity constraints (Ãlvarez-Rosales and González-López, 1995; MartÃn-Barajas et al., 2001). During flooding events, mostly silt and clay are transported in suspension into the lake basin and continuously accumulate over larger areas in the Laguna Salada. Profiles 4973, 4965, 4957, and 4949 have lengths of 14, 11, 9, and 7 km, respectively, and cross the LSB in a northeast to southwest direction (Figs. The white interval matches unit 3 in well ELS-2 and consists of an â¼200-m-thick sandstone that underlies a thick interval of mudstone with subordinate siltstone and sandstone (unit 4) (MartÃn-Barajas et al., 2001).

The Laguna Salada fault (LSF) and the low-angle Cañada David detachment fault (CDD) control the basin architecture and subsidence and represent two distinct basin domains (Siem and Gastil, 1994; Axen, 1995; Mueller and Rockwell, 1995; Axen et al., 1999; Spelz et al., 2010). ELS-1 to ELS-3 are the exploration wells drilled by the Comisión Federal de Electricidad (CFE). The thick black lines running along and across the LSB are the seismic-reflection profiles (owned by Petróleos Mexicanos [PEMEX]) processed, interpreted, and reported in this study. The first survey, which was carried out in 1991, was with five seismic stations located in the northern part of the basin recording from July 8 to December 17. oscar baylon grecco. In profile 4973 (Fig. 5B). [12][13] El artefacto bautizado como âCimarrón Iâ alcanzó una altitud de más de tres mil metros y en el proyecto participaron asesores de la NASA y de la SJSU.

Gallardo-Mata, Arturo MartÃn, Luis Munguia, Francisco Suárez-Vidal; Subsurface constraints of an active detachment fault in Laguna Salada Basin, Baja California, México, from interpretation of seismic-reflection profiles. Historical seismicity (Ellsworth, 1990; Doser, 1994; GarcÃa-Abdeslem et al., 2001; Hough and Elliot, 2004) and paleoseismological studies (Mueller and Rockwell, 1991, 1995; Fletcher and Spelz, 2009; Fletcher et al., 2014) demonstrate that LSB is controlled by the active LSF and the Cañada David detachment fault. The quake originally was believed to have occurred on the Laguna Salada Fault, which is about 60 kilometers (37 mi) to 80 km (50 mi) long and straddles the California–Baja California border. Esta página se editó por última vez el 23 nov 2020 a las 18:35. The seismic resolution in the upper part of seismic lines (e.g., <300 m) is of lower quality because industrial interest in the depth structure commonly filters the high-frequency signal during acquisition. Southeast, this earthquake and its aftershocks ruptured previously unidentified faults in the delta plain south of the epicenter and evidenced a wider plate boundary zone at this latitude (Hauksson et al., 2011; Chanes-MartÃnez et al., 2014). 2). This seismic facies implies a small lithological contrast among strata and probably represents sandstone-siltstone facies, as indicated in profile 4957 located 1.7 km to the south of well ELS-2 (Fig. Length 34.2 mi Elevation gain 1,437 ft Route type De punto a punto Two seismic profiles indicate the detachment fault dips 17°â20° west, has a minimum of 10.1 km of slip, and accumulates a sedimentary wedge more than 2.5 km thick in the west-central part of this basin domain. 2) forming a releasing stepover. Near its intersection with the Laguna Salada fault, the Cañón Rojo fault has a vertical offset of â¼1.3 km measured from the stratigraphic thickness of Plio-Pleistocene deposits, including the locally derived Red Beds, the Grey Gravel units, and the Palm Spring and Imperial deposits (Dorsey and MartÃn-Barajas, 1999). 4 and 6). Continuous high-amplitude reflections at â¼1 km deep are observed in both seismic lines. Southward the modern basin becomes narrower and connects through a â¼5â10-km-wide inlet with the modern delta plain of the Colorado River and the tidal flats of northern Gulf of California (Fig. Microearthquake and tectonic studies within the LSB region were completed in two surveys (Fig. Between the two ends, basement loses its distinctive high- amplitude characteristic and passes southward into a zone of chaotic reflectors (from cdp 5750â6150). Facies 1 and 2 are high-amplitude, laterally continuous reflectors that represent flooding and prolonged lacustrine conditions. 3). The CCD produces fault scarps along the west side of Sierra El Mayor (from Axen et al., 1999; Fletcher and Spelz, 2009; Spelz et al., 2010). The red lines are the interpreted fault. Laguna Salada is unique among these examples because it is the only documented site of coeval active deformation. 5A). Southward the flat topography of the basin contrasts with the steep relief of bounding ranges of Sierra Juárez to the west and Sierra Cucapah and El Mayor to the east (Fig. Seismic facies 1 and 2 predominate in the east and central portions of seismic profiles where the depocenter accumulates thick, fine-grained sedimentary sequences. The Laguna Salada Basin is an active asymmetric depression structurally controlled by the Laguna Salada fault and the Cañada David detachment fault. Ejido Laguna Salada (Baja California) Conozca el diminuto pueblo de Ejido Laguna Salada a través de sus fotos, sus mapas y sus estadísticas de población. (2001) for a local seismic network. Crystalline basement at â¼1500 m depth also matches the stratigraphic log of the exploratory well ELS-2. 4A). Furthermore, in the southernmost seismic image (profile 4973, Fig. Above â¼400 m, the poor resolution prevents further seismic interpretation, and the activity of faults located farther east in the sedimentary wedge is not imaged (cf. In the second survey, these five stations were placed south, recording from April 27 to September 17, 1992. Mientras que las temperaturas mÃnimas oscilan entre los 25°C en verano hasta los 4°C en invierno. Hotels in Laguna Salada. The supradetachment basin domain accumulates a sedimentary wedge more than 2.5 km thick in the west-central part of the basin, and the subsurface portion of the Cañada David detachment represents 24% of extension in the western main plate boundary zone. ... Laguna Salada. 1). (A) Profile 4957 (see inset map and Figs. Instead, it is a dry lake that can be found in the Colorado River Delta, which is where the Colorado River flows into the Gulf of California. This geometric projection suggests that basement in the hanging wall intersects the Laguna Salada fault at â¼3.8 km below the surface, assuming that the Laguna Salada fault maintains a â¼70° dip to the west (Fig. Shorter, high-amplitude continuous reflectors that lap on the west distinctively form the lower part of this interval and form local angular unconformities within a smaller (2â3-km-wide) depocenter (Fig. «Lake Cahuilla´s Little Sister: Exploring the role of Laguna Macuata in Colorado Desert Prehistory.», «Preliminary Study of the Fishery in Laguna Salada, Baja California», «Elaboración de dos Programas de Desarrollo Comunitario Sustentable de la Reserva de la Biosfera del Alto Golfo de California y Delta del RÃo Colorado», «Laguna salada, trampa mortal durante los infernales mese de verano», «Adiós a Pavarotti en el desierto de Mexicali», «Listo Pavarotti para su concierto en Laguna Salada», «Transmitirán el domingo aterrizaje en la Laguna Salada», «Lanzan alumnos de la UABC cohete experimental», «Listo Ultra Maratón en el desierto de la Laguna Salada», «Calendario Mexicano e Internacional de Ultramaratones», «Acta 2013_14 de la secretarÃa académica del instituto de astronomÃa de la UNAM (página 4)», «Confirman corredores participación en la off-road del CODE», https://es.wikipedia.org/w/index.php?title=Laguna_Salada_(Baja_California)&oldid=131157707, Wikipedia:ArtÃculos con datos por trasladar a Wikidata, Wikipedia:ArtÃculos con coordenadas en Wikidata, Licencia Creative Commons Atribución Compartir Igual 3.0. The lowermost stratigraphic unit in Laguna Salada crops out in the footwall block of the Cañon Rojo fault, a N-Sâtrending, high-angle normal fault forming a dilatational stepover along the Laguna Salada fault (Fig. 5B) contains a west-dipping fault that produces â¼500 m vertical offset of the acoustic basement in the hanging wall of the CDD. For both (A) and (B), yellow line is the acoustic basement. This depocenter broadens upwards and probably represents a broader zone of subsidence and/or an increase in sediment supply. Bouguer anomaly is shown with gray contours every 10 mGals (taken form GarcÃa-Abdeslem et al., 2001). A new continuous reflector of facies 1 covers the lens-shaped deposit and defines a new sequence. Geosphere 2016;; 12 (4): 1283â1299. It is shaped somewhat like an hour-glass, long and skinny and very narrow at the center. This unit also includes metric to sub-metric evaporite deposits and locally derived conglomerate and breccia. Basin-margin alluvial and marine conglomerate and breccia locally crop out in the north and northwestern foothills of Monte Blanco dome (Siem and Gastil, 1994; Vázquez-Hernández et al., 1996). The boundary of flooding is displayed with white line. (2001), is located along the Laguna Salada fault, Cerro Prieto geothermal field, and the eastern front of Sierra Juárez, and only 17 events lie within the Laguna Salada Basin. The seismic source for the acquisition of the seismic data was dynamite. The lower lens shape sequence is â¼4 km wide and â¼500 m thick, and the seismic reflections are parallel to the acoustic basement (Fig. Otro escenario sin igual se encuentra en Laguna Salada , un verdadero oasis entre las montañas. South of the Chupamirtos fault, Laguna Salada Basin is an active supradetachment basin, whereas north of the Chupamirtos fault, the Cañón Rojo stepover produces a â¼10-km-wide pull-apart basin laterally controlled by the Laguna Salada and Chupamirtos faults. Laguna Salada (“salty lagoon”) is a vast dry lake some 10 meters below sea level (sometimes wet – sometimes dry) in the Sonoran Desert of Baja California, 30 km southwest of Mexicali. 2). Upwards, facies 1 is laterally continuous both east and west and expands over a broader depocenter. Abbreviations: LSFâLaguna Salada fault; CRFâCañón Rojo fault; CHFâChupamirtos fault; CDDâCañada David detachment; SJFZâSierra Juárez fault zone, Indiviso fault (from Fletcher et al., 2014); MGEâmain gulf escarpment; PacâPacific plate, NAMâNorth American plate; ELS1, ELS2, and ELS3 are exploration wells by Comisión Federal de Electricidad. The south domain is a supradetachment basin controlled by the Cañada David detachment fault. Nevertheless, an important observation is the eastward thickening of the two lowermost sequences adjacent to CDD in profile 4965, whereas the three upper sequences are symmetric lenses, and the thicker intervals are located 6â8 km west of the breakaway fault of the detachment (Figs. Intervals of low to medium amplitude laterally wedge out westward and interfinger with chaotic reflectors of facies 4. Farther south, line 5076-c confirms that crystalline basement is very shallow in the east flank of Sierra Las Tinajas. 4). We interpret facies 4 as coarse-grained, high-energy alluvial fan deposits prograding over the basin floor from the west in the range front of Sierra Juarez. The exploration wells drilled by the Comisión Federal de Electricidad (CFE) in the LSB are depicted as green dots (ELS-1 to ELS-3). Active-source, seismic-reflection data constrain the geometry of the active detachment fault and indicate two structural domains. FAULT INVOLVED: Laguna Salada fault zone. p. ocean. As in previous figures, subhorizontal lines (blue and yellow): the HâA horizon reported by MartÃn-Barajas et al. Geologic cross sections derived from the seismic profiles: 4973 (AâAâ²), 4965 (BâBâ²), and 4957 (CâCâ²). This is a dry lake, shaped like a geometric shape of a rhombus. Faults interpreted in the geo-seismic sections are indicated by a yellow line with a dot in the downthrown block. My original plan was to explore Laguna Salada by driving on the dry lake bed (playa) surface — but it did not turn out to be dry. Discover the beauty hidden in the maps. Nevertheless, a crude estimate of the rates of extension and vertical subsidence suggests a ratio of 3:1, respectively. The two northern transversal profiles 4957 and 4949 (Figs. Only acoustic basement and two faults are interpreted due to lower resolution of this seismic image. thesis], Centro e Investigación CientÃfica y Educación Superior de Ensenada. 4B). The LSF and the CDD fault are kinematically linked by the Cañon Rojo and Chupamirtos faults (Mueller and Rockwell, 1991) (Fig. 6B) clearly show that laterally continuous reflectors (seismic facies 1 and 2) penetrate westward and interfinger with facies 3 and 4 produced by alluvial fan deposits. In profile C, the projection of acoustic basement to intersect the Laguna Salada fault yields a depth to basement of â¼3800 m assuming the fault dips 70° west. 4B), the lowermost stratigraphic unit is lenticular, and seismic reflectors are parallel to the acoustic basement. 1 and 2) controls the basin architecture. [8] El antes citado evento, fue parte de una de las últimas giras del tenor italiano Luciano Pavarotti. This new structural configuration progressively formed the semi-closed basin with an entrance from the south end connecting LSB with the delta plain and tidal flats of the northern Gulf of California. 22860, México. The largest fault is west dipping and produces â¼500 m of vertical offset. The acoustic basement in the hanging wall deepens to a maximum of â¼2100 m in profile 4973 and to â¼2500 m in profile 4965 (Figs. Well ELS-2 is closer to intersection of seismic lines 4957 and 5076-a, and wells LS-1 and LS-3 are 10â15 km away from the nearest seismic line and provide indirect lithological and stratigraphic constraints (Fig. The inset map shows the major tectonic features of northwestern Mexico and the location of the study area (i.e., the Laguna Salada BasinâLSB). During lowstand sea level, Laguna Salada is intermittently dry, and playa-lake deposits must enhance progradation of alluvial fan and eolian deposits into the basin floor. Baja California Laguna Salada La Laguna Salada es una depresión arenosa que comienza en la inmediación suroeste del cerro El Centinela y se extiende hacia el sur por entre la sierra Cucapá y la sierra de Juárez , dentro del municipio de Mexicali, B. C. , México . Another prominent relief in the acoustic basement occurs at the northwest end of profile 5076-b (Fig. Maphill is more than just a map gallery. Ofrece vistas panorámicas y es calificado como difícil. The Chupamirtos fault apparently constitutes the hard link between the Laguna Salada and the active portion of CDD. Several faults cut the basement along the west side of LSB (Figs. El 1 de agosto de 2012 tuvo lugar el primer lanzamiento en el estado de Baja California de un cohete, fabricado por alumnos de la carrera de ingenierÃa aerospacial del centro de ingenierÃa y tecnologÃa de la UABC. For these estimates, we infer that the acoustic basement is a flat ramp that deepens at an angle of â¼20° similar to average basement dip in profile 4957 (Fig. Sequences 3, 4, and 5 maintain their thickness across the seismic profile 4973, and seismic reflections gently dip toward the east, whereas sequence 2 is wedge shaped and nearly 1000-m-thick sediments juxtapose the CDD. Baja California, Mexico: 2009. 1). This well did not reach the Imperial marine mudstone unit inferred to lie at a depth as recorded in stratigraphy of the Cerro Colorado basin (Vázquez-Hernández et al., 1996). pesq. 5).

Up to â¼700 m of Late Pliocene to present lacustrine-estuarine deposits interfingered by progradational and retrogradational alluvial wedges represent the modern structural and sedimentary setting in LSB (Figs. However, the low resolution and low number of seismic lines prevent a detailed interpretation and correlation of most sequence boundaries. Offshore, the Angel de la Guarda detachment coexisted during dextral shearing in the Tiburon and Amado dextral oblique faults that controlled the early separation of the Baja California peninsula from mainland México (MartÃn-Barajas et al., 2013). Other interpreted faults are red lines (see Fig. facies 3) is located above the crystalline basement in profile 5076-a (Fig. Red dots indicate epicenters of the larger historical earthquakes reported (year and magnitude) by Ellsworth (1990); the yellow and green dots are the microseismicity reported by GarcÃa-Abdeslem et al. (2001) and the acoustic basement, respectively. Early extension and subsidence in the LSB likely started in Late Miocene as indicated by faulted ca. Up section, the concave shape of reflectors shift toward the east, and sedimentary sequences thicken in the east and central parts of each depocenter. 2). As the detachment fault becomes low angle, the horizontal component increases and displaces the depocenter basinward as proposed by Fletcher and Spelz (2009). The main gulf escarpment in Sierra Juárez contains a northwest-trending west- and east-dipping normal faults array, each with relatively small offset (Romero-Espejel, 1997; Mendoza-Borunda et al., 1998). 1 and 2). We interpret that sequence 1 in profile 4973 (Fig. The seismic activity reported by the seismological network of the northwestern México (RESNOM-CICESE) before the El MayorâCucapah earthquake (EMC) of April 10, 2010 (Mw 7.2) (Hauksson et al., 2010) indicates larger seismic activity in the study area concentrated along the western basin margin, after the seismic activity focused mainly along the eastern basin and continues in this sector (December, 2015). These two major faults interact with other faults and accommodate transtensional shearing in the easternmost plate boundary zone (Fletcher et al., 2016). We recognize four seismic facies representing the dominant sedimentary environments. 5A). The modern lake basin is bordered by a 5â15-km-wide belt of coalescing alluvial fans derived from Sierra Juárez in the west and by a narrower 0.5â3-km-wide belt of alluvial fans fed from the Sierra Cucapah and Sierra El Mayor in the east. La Laguna Salada Tiene una longitud de 60 kilómetros, inicia al suroeste del cerro El Centinela y se extiende hasta la sierra Cucapá y Sierra de Juárez, en Mexicali. Every Sunday for the last two years Gallardo has cleared the area of trash and planted date palms near the mouth of a dry 35 by 11 mile lake basin known as the Laguna Salada. Instead, it is a dry lake that can be found in the Colorado River Delta, which is where the Colorado River flows into the Gulf of California. Transversal profiles in southern Laguna Salada Basin domain show that seismic facies 4 dominate the western portion of the seismic images, and facies 1 and 2 dominate the eastern part, where depocenters define the thicker sedimentary fill. From profile 4965 (Fig. High-amplitude continuous to discontinuous reflectors (facies 1 and 2) above basement alternate at intervals tens to a few hundred meters thick. Profile 4957 captures only half basin width, but depth to basement is more than 2.4 km farther east as indicated in well ELS-1 (Fig. Profile 5076 comprises three segments (a, b, and c) with lengths of 27 km, 30 km, and 13 km, respectively, and crosses all four transversal profiles (Figs.
