Biostratigraphy and Lithostratigraphy of Asmari Formation in The Chenareh Anticline and compare with Amiran Anticline Stratigraphical section in the Zagros Folded Belt, Lorestan, Iran

Peiman Rajabi

Volume 32, Issue 4 , December 2022, , Pages 177-192


  The Asmari carbonate formation in Lorestan is seen in the form of a medium to the thick limestone-rich layer of benthic foraminifera and often as a rock formation. In this study, the stratigraphic sequence of Asmari carbonate formation in the Chenareh Anticline section located in the south of Lorestan ...  Read More
