The Neoproterozoic Sindreth Basin is one of the three important and isolated basins in the Erinpura Granite Terrane of the Aravalli Craton (NW Indian Shield). Lithopackge of the Sindreth Basinis grouped into the lower Khambal and upper Angor formations. The geochemical classification of the Khambal Formation reveals an arkosic nature of the phyllite and subarkosic – sublitharenitic nature of the quartzite. The source terrane was predominantly felsic with minor small mafic components as well as distant mafic components based on signatures of anomalous enrichment of Cr. The source area of these rocks was subjected to moderate chemical weathering that was punctuated by intermittent pulses of extreme weathering, possibly under sub-humid temperate climate. The cyclic nature of lithologies in the Sindreth Basin indicates that deposition occurred in an unstable tectonic regime and chemical characteristics of clastics from the Khambal Formation indicate a tectonically active source terrane. It is proposed that the Sindreth Basin opened in response to disintegration of the Supercontinent Columbia and reassembly of Rodinia, associated with the building up of the Malani Supercontinent comprising of India, the Arabian - Nubian Shield, Madagascar and China.
