Title

MINERALOGY AND GENESIS OF BENTONITE OF SAR KAVIR AREA (SOUTH OF DAMGHAN)

Pages

  87-100

Abstract

 Introduction: The studies area with coordination of 54º 30' E and 35º 18' N is located in the MOALLEMAN AREA, in the South Western of Torud Quadrangle. In the structurally – sedimentary Zoning, this area lies in depression part. In the north part of worked area crops out the equivalent of Karaj Formation, from SOSANVAR Village to south of Gandy Kaolin Mine. Lithologically this formation is composed of shale, marl, micrite, limestone, dolostone, radiolarite, tuffite, zeolite, and bentonite, with the age of Lutecian (Middle Eocene).Aim: This paper has been focused on the types, composition, and environment of bentonite layers of SOSANVAR Bentonite Ore.Material and Methods: in the study we used from thin sections, XRD, and XRF.Reasons of use of the analyses were select of appropriate rocks and determination of clay type at BENTONITES and investigation of its ionic exchangeable.Results: According to studies and investigations the BENTONITES has been formed from acidic volcanic glass (ryolitic to dacitic), and their magmatic series is calkalkaline, but according to some evidences the magmatic series is ALKALINE.Conclusion: Changing glasses to bentonite has been occurred under diagenesis conditions, in shallow sea (e.g. Lagoon). The type of clay of this WYOMING – type bentonite is SMECTITE.
