Geology and evolution of the Late Pleistocene-Holocene La Primavera caldera complex, western Trans-Mexican Volcanic Belt
La Primavera caldera is located in the western part of the Trans-Mexican Volcanic Belt. The landscape is represented by caldera-rim, intra-caldera, and extra-caldera domes and volcanoes associated with pyroclastic, lacustrine, and volcaniclastic deposits, all of which reflect a complex caldera evolution. La Primavera erupted ∼95 ky ago through the emission of the Tala ignimbrite, resulting in an 11-km wide caldera. Post-caldera activity occurred …
Detailed geomorphology of debris avalanches of El Estribo volcanic complex (Central Mexico)
The El Estribo Volcanic Complex, located to the south of Pátzcuaro Lake (Central Mexico), forms an elevation based on a shield volcano crowned by a cinder cone. Two debris avalanches, dated at 28,000 and 14,000 ybp, cover an area of 4 km 2 with a typical hummocky topography. The zone is a state natural protected area with no previous studies of hazard and risk from mass movement processes. Herein, we present a detailed geomorphological map of the…
Landslide impact on the archaeological site of Mitla, Oaxaca
Some large landslide deposits are recognized within and around the Mitla archaeological site, which is located in a very seismically active region cut by the Tehuacan‐Oaxaca fault system. Previous studies have shown that this fault system has produced coseismic ruptures and associated earthquakes in the past. Our work on the Mitla landslide deposits clearly demonstrates that their morphology and nature are typical of dry‐rock avalanches. Thus, co…
Geology and stratigraphy of the Mexico Basin (Mexico City), central Trans-Mexican Volcanic Belt
We present a new geological map of the Mexico Basin (Mexico City) based on field descriptions, a compilation of data from previous publications, and new 40 Ar/ 39 Ar geochronology data. The oldest rocks described in the Mexico Basin are Cretaceous limestones, overlaid by Oligocene (26.0 Ma) and Miocene (22.8–5.0 Ma) volcanic successions, followed by Pliocene-Pleistocene (3.7–1.2 Ma) to Recent volcanic rocks around the basin. The Mexico basin is s…
Geology of the late Pliocene – Pleistocene Acoculco caldera complex, eastern Trans-Mexican Volcanic Belt (México)
We present a new 1:80,000-scale geologic map of the Acoculco caldera (Ac) located between the states of Puebla and Hidalgo in eastern México. The map, encompassing an area of 856 km2, is grounded on an ArcMap data set and is supported by nine new 40Ar/39Ar dates. The caldera lies upon Cretaceous limestones and Miocene to Pliocene volcanic rocks (13–3 Ma). The caldera consists of 31 lithostatrigraphic units formed between 2.7 and 0.06 Ma that incl…
Geology of the late Pleistocene Tres Vírgenes Volcanic Complex, Baja California Sur (México)
The geological map of the Tres Vírgenes Volcanic Complex (TVVC) Baja California Sur, México consists of three northeast-southwest aligned stratovolcanoes named from older to younger, El Viejo, El Azufre, and La Virgen. The map (scale 1:20,000) comprises an area of 856 km2 edited on an ArcMap data set. The map compiles previous studies combined with new mapping and stratigraphy supported by 5 new 230Th/U geochronology in zircons. The TVVC sits on …
Geology of La Reforma caldera complex, Baja California, Mexico
A new geological map at 1:50,000 scale of La Reforma Caldera Complex has been produced applying modern survey methodologies to volcanic areas. This map aims to represent a reliable and objective tool to understand the geological evolution of the region. La Reforma Caldera Complex is a Pleistocene nested caldera located in the central part of the Baja California peninsula, Mexico. The twelve formations defined within the Quaternary volcanic record…
Late Formative Flooding of Izapa After an Eruption of Tacaná Volcano
Between the years of 30b.c.toa.d.80, during the Late Formative period, the site of Izapa was flooded by lahars associated with an explosive eruption of the San Antonio volcano (part of the Tacaná Volcanic Complex). Computer simulations suggest that hot pyroclastic flows did not impact Izapa directly, but did impact the region considerably, filling and clogging the Cahuacan and Mixcun rivers with hot debris. The material was quickly saturated by h…
