Lithology and environment
Primary lithology: | fine,medium,dolomitic,intraclastic sandstone |
Includes fossils? | Y |
Lithology description: Ferruginous sandstone matrix. The rock is a medium-to fine-grained sandstone with pelitic intraclasts in tabular bodies | |
Environment: | "floodplain" |
Geology comments: Sedimentological studies of Recent lake Ezequiel Ramos Mexia show that the area is a depositional fluvial environment crossed by an association of shallow water bodies, some of them relatively wide, subjected to a regime of sporadic seasonal flooding. The climate was temperate with alternate rainy and dry periods |
