Carbonate- Terrigenous deposits (Paleocene?- Eocene) of Fil-e-Zamin vally in northeast of Tehran (Central Elborz)

Abstract:
      The carbonate and detrital deposits (Paleocene? to Eocene) are located in fil-e-zamine area (N 36? 50' 30'' , E 51? 52' 30''), northeast of Tehran. These deposits overlie the Shemshak, Dalichai and Lar Formations and Upper Cretaceous deposits with faulted-erosional contact and underlay by the Karaj Formation ttufs with unconformity. The field observation and thin-section studies of these deposits indicate terrestrial (fluvial-lacustrine) and marine depositonal environment. The marine deposits include of carbonate and terrigenous facies. The terrestrial deposits are consist of fluvial red shale and sandstone and dark limestone of lacustrine facies. The lacustrine deposits consist of lime mudstone, charophyta biocalst wackestone/ packestone and fenestral algal boundstone.
