Abstract
The fining upward sequence of Proterozoic Rajgarh Formation mainly consists of feldspathic sandstone, quartzarenite, bands of shale and have a restricted lateral extent with variable palaeoflow pattern. Eight major lithofacies identified from this succession collectively indicate fluvial to marginal marine depositional set up. The Rajgarh quartzose to feldspatho-quartzose siliciclastics are fine- to coarse grained, poorly- to moderately sorted derived from a stable continental block provenance that deposited in a fault bounded graben. The deposition of the Rajgarh siliciclastics can be best explained by short transportation, high relief and fast sedimentation in rapidly subsiding fault-bounded basin and indicate radial slope and source located in the Dausa uplift in the east and banded gneissic complex (BGC) in the south and southeast.
