Abstract

The Ingiin-Nars properly is located in the southern part of the Sainshand sedimentary Basin. The basins is filled with syn & post riflogenic alluvial, fluvial, and lacustrine and limnic sedimentary rocks of Early to Late Cretaceous age. which are covered by Paleocene to Quaternary alluvium loose sediments. Paleozoic to Jurassic, meta-sedimenls and granites form the basement of the basin. The older sequences were affected by the Caledonian progeny. Basins were down faulted during Cretaceous time. The study sandstone of the Ingiin Nars area is classified as arkosic type. Considering the sandstone modal composition the studied sandstones are derived from continental block orogin.
