بیواستراتیگرافی سیستم پرمین در برش گلستانه (دره الیکا)

  Abstract:

In order to study the permian system in central Alborz Golestaneh section in       Elika valley ( near the Tehran- Chalos  road ) has been sample done. The aim of this study is biostratigraphy of  permian sediments and determine the geological age and stages by the microfossils ( principle foraminifera ). In this section permian sediments include: conglomerate - sand stone - lime stone - Volcanic sediments - dolomite. That permian sediment’s overlaying on carboniferous sediments (namurian - moscovian) with disconformity and underlaying Teriassic sediments (scytian ) with disconformity.
