... as the source rocks for the Delwara Formation from the Lower Aravalli Supergroup. The Delwara sandstones show enrichment of Zr and depletion of Ti and Sc, indicating a passive-margin depositional environment. Immature sandstones of the Middle Aravalli Udaipur Formation incorporate detritus from ca. 1.97–1.79 Ga...
