Popis: 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.
