Con base en un análisis estratigráfico realizado tres diferentes áreas del norte Estado de Oaxaca y sur Puebla, se presenta modelo la evolución peleogeográfica para el Jurásico-Cretácico porción Terreno Mixteca. Las capas más antiguas secuencia mesozoica (Toarciano (?)-Aaleniano), expuestas área Tezoatlán-El Rosario, consisten estatos conglomerados, areniscas, limolitas lutitas con algunas carbón. Estas acumularon después cambio régimen tectónico levantamiento, activo desde Triásico...

The Salado River fault (SRF) is a prominent structure in southern Mexico that shows evidence of reactivation at two times under different tectonic conditions. It coincides with the geological contact between structural high characterized by Palaeozoic basement rocks to north, and an ∼2000 m thick sequence marine continental accumulated Middle Jurassic–Cretaceous basin south. Rocks along within zone up 150 across record crystal-plastic deformation affecting metamorphic Acatlán Complex. Later...
In southeastern Mexico, Jurassic and Cretaceous rocks are buried beneath voluminous Palaeogenesedimentary successions, the origin of which is still under debate. Some authors proposed that these Palaeogene successions were derived from Proterozoic, granulite-facies Oaxaquia, a microcontinental block exhumed during Late Cretaceous–Palaeogene orogenic event driven by variations in convergence rates along Pacific margin North America. Alternatively, other suggested mostly Guatemala suture...
ABSTRACT This work offers a large-scale approach to the stratigraphy of an area in southern Mexico that includes three different tectono-stratigraphic terranes and displays great geological diversity. In attached 1:100,000-scale map, stratigraphic information is grouped according occurrence sedimentary basins. Here, we describe basement six basins turn. four basins, thick Mesozoic successions accumulated on record evolution from continental environment during Triassic–Jurassic, marine...
ResumenSe propone formalmente a la Formación Chivillas, unidad litoestratigráfica clave para descifrar el registro sedimentario de Cuenca Cuicateca.Su localidad tipo se encuentra en Barranca Las Salinas al noreste Tehuacán, donde las rocas están prácticamente sin deformar.La Chivillas consiste derrames basálticos frecuentemente con estructura almohadilla y depósitos siliciclásticos producto corrientes turbidíticas flujos escombros que forman una sucesión volcanosedimentaria muy gruesa...
The origin of the Oligocene turbidites from Cerro Pelón area in south Gulf Mexico proposed by Ortega-Flores et al. (2018) is disagree with interpretations made Molina-Garza (2019), which main criticism based on U-Pb ages detrital zircons matrix a conglomerate unit, they refer to as 'Nanchital Conglomerate', well presence limestone, gabbros, and mafic protolith-derived clasts. (2019) basically interpret Nanchital Conglomerate Miocene age, was sourced mainly metamorphic complexes including...
This paper presents a 1:50,000 scale map and lithostratigraphic synthesis of the Huajuapan region, which has one Mexico's most complete geological records. The region represents critical area for understanding marine flooding process after breakup Pangea. formed small extensional basins, such as Ayuquila basin, dismantled primary fluvial system that drained ancient central Pacific slope In basin developed in tectonic SSE–NNW extension framework prevailed from Middle Jurassic to Turonian. its...
Puebla State, Mexico, stands out with its diverse geological features, ranging from Precambrian and Paleozoic crystalline basements to the Pliocene-Quaternary major volcanoes. It is divided into three distinct regions: northern region predominantly marine successions, where outcrops a volcano-sedimentary succession aged between 171.3 ± 0.5 Ma 168.6 0.4 Ma; central region, part of Trans-Mexican Volcanic Belt; southern mainly characterized by multitude continental units on basements.
