| Abstract: | Stratigraphic status of the polymictic conglomerate (outlier of erstwhile Delhi system) exposed from east to northwest of Salumber town (western India) is controversial. Detailed mapping on 1:25000 scale indicated that the polymictic conglomerate has distinct overlapping relationship with the lithounits occurring to its south. The conglomerate contains clasts of the overlapped lithounits. Overlapping disposition and clast characteristics confer younger status to the conglomerate with respect to the overlapped lithounits. Most earlier workers regarded the conglomerate to be older than the overlapped lithounits. The conglomerate is correlatable with the Debari conglomerate of the Aravalli sequence. As the conglomerate unit has been a significant marker horizon in the Aravalli stratigraphy, the proposed revision in its stratigraphic status would lead to resolving certain ambiguities in the Paleoproterozoic Aravalli stratigraphy of southern Rajasthan. |
