Near Santa Cruz Nuevo, the unit contains casts of dinosaur ichnites (Silva-Romo, Mendoza-Rosales, Campos-Madrigal, Morales Yáñez, et al, 2018). The youngest detrital zircon contained in the Otlatepec Formation suggests an early Cretaceous age (Silva-Romo, Mendoza-Rosales, Campos-Madrigal, Morales Yáñez, et al, 2018).…”

“…The Paleogene Atzumba basin is a half-graben at the foot of the north-south trending Chazumba fault. The basin contains six stratigraphic units: The Atzumba Formation ( ) (Silva-Romo, Mendoza-Rosales, Campos-Madrigal, Morales Yáñez, et al, 2018) consists of a thick (approximately 300 m) succession of mudstone, sandstone, and matrix-supported conglomerate. The conglomerate beds, which are up to 3 m thick, contain clasts of gneiss, schist, polycrystalline quartz, amphibolite, sandstone, andesite, chert, and limestone.…”

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 a great geological diversity. In the attached 1:100,000-scale geological map, the stratigraphic information is grouped according to the occurrence in sedimentary basins. Here, we describe the basement and six basins in turn. In four of the sedimentary basins, thick Mesozoic successions that accumulated on the basement record the evolution from a continental environment during the Triassic-Jurassic, to a marine environment, comprising clastic and calcareous deposits, during the early Cretaceous. Cenozoic ages are recorded in clastic and lacustrine sedimentary successions and in abundant igneous rocks in two of the continental basins. The geodatabase was compiled in GIS format and subsequently imported in vector graphic software to achieve a design similar to the cartographic series 1:100,000 CARTA GEOLÓGICA DE MÉXICO of the Instituto de Geología, UNAM.

The Salina Cruz and Puerto Ángel beach areas in the Gulf of Tehuantepec, Mexican Pacific coast represent an important economic sector of the region. In this study, the mineralogy and geochemistry of bulk sediments, and geochronology of 400 detrital zircons recovered from the beach sediments were analysed to investigate their origin. The sediments are abundant in quartz, feldspar, ilmenite, cordierite, aragonite and anorthite. The chemical index of weathering revealed a moderate to intense weathering in the source area. The chondrite normalized REE patterns of bulk sediments are similar to the found in the Upper Continental Crust, suggesting the derivation of sediments from felsic igneous rocks. The REE patterns of zircons and the trace elemental ratios reveal a continental crust origin. Zircon U–Pb ages in the Salina Cruz beach were represented by Proterozoic (~545.1–1314.1 Ma; n = 170) and Cenozoic (~0.01–66 Ma; n = 20). The Puerto Ángel beach was abundant in Proterozoic zircon grains (~600.9–1171.4 Ma; n = 109) and followed by Mesozoic grains (~73.78–246.9 Ma; n = 40). The comparison of zircon U–Pb ages of this study with probable source rocks reveals that the Oaxaquia Terrane and Chiapas Massif Complex were the major contributors of Proterozoic zircons to the coastal areas. Similarly, the results indicate that the Cenozoic zircons were contributed by the Chiapas Massif Complex, coastal batholith and Cuicateco Terrane. The Mesozoic zircons are very few, derived from the nearby Xolapa Complex and the Chuacús Terrane.
