Petrofacies, Provenance and Tectonic Setting of Nimar Sandstone (Lower Cretaceous), Rajpipla-Jobat Area

The Nimar Sandstone were studied with a view to understanding the nature of the Narmada  basin and its tectonic setting during an important event which took place on a global scale. The sandstones are predominantly quartzarenitcs composed mainly of several varietics of quartz, mica, rock fragments, feldspar and heavy minerals derived from the underlying Plecambrian basement. An integrated approach suggests that the Nimar Sandstone was derived from fault-bound uplifts of continental basement rocks and accumulated without much transport in the incipient rift belt of the Narmada basin.
