Les ensambles geologiques du Mexique meridional. Evolution geodynamique durant le mesozoique et le cenozoique

Abstract

Different geological realms for the South of Mexico and for Central America are defined and their paleogeographic and structural evolutions described. During Mesozoic time their story is tha of the relationship between the Tethys and the Pacific. Their Cenozoic story is linked with the evolution of the Eastern Pacific. The whole geological, geophysical and oceanographical data allow to propose an evolutive model, whose nine stages are successively examined.
