Abstract :
Eocene sediments in the western part of Binalud zone contains alternations of marl, sandstone and conglomerate. In this study area, sediments have 391 meters (thick) and its lower contact is not distinct and in the upper part it reaches to neogen red beds. Most collection fossils in this area are nummulites, furthermore some genues and species of? other foraminifera are recognized. From 24 genus and 34 species of benetic and planktonic foraminifera which are recognized 8 species are nummulites and others are related to another foraminifera. This? assemblage? indicates? a? lutetian (middle Eocene) stage? for? these? deposits. Microfacies? study show that this sediments are deposites in a shallow marine that continue to transsgration.
