Robabe masoomi; Yoseph Rahimsouri; Hemayat Jamali; Ali Abedini

Volume 31, Issue 2 , September 2021, , Pages 123-136

https://doi.org/10.22071/gsj.2020.219967.1760

Abstract
  The action of alteration processes on the Eocene tuffs has led to the formation of a spread argillic alteration zone in the Kamar district (south of Ardebil, Tarom-Hashtjin Zone). The aim of this study is to determine the factors controlling argillic alteration, using mineralogical studies and chemical ...  Read More

Abstract
  Chahreeseh bentonite deposit is located at ~55 km northeast of Isfahan, structural zone of Central Iran. This deposit has layered and massive form and includes six discrete outcrops. The field observations showed that the ores are genetically related to Oligo-Miocene tuff breccia. The mineralogical studies ...  Read More

Geochemical Studies of Permian Bauxite-Kaolin Deposits in North of Saqqez, Kordestan Province

A. Abedini; A. A. Calagari

Volume 20, Issue 79 , January 2011, , Pages 67-74

https://doi.org/10.22071/gsj.2011.55040

Abstract
  Depositional cessations during Permian period in north of Saqqez were associated with development of lenses of bauxite-kaolin ores in Ruteh carbonate formation. In one of these lenses considered, six lithologic units were recognized which are from bottom to the top, (1) dark brown red, (2) violet, (3) ...  Read More
