Title: Storm event beds in a Paleoproterozoic Rift Basin, Aravalli Supergroup, Rajasthan, India

Abstract: Storm event beds in the Paleoproterozoic riftogenic sedimentary succession of Aravalli Supergroup are described from a 12.8 m-thick sandstone-mudstone interbedded unit in Zawar area, Rajasthan, India. The storm event beds include different primary structural assemblages indicating deposition from waning storm current. Sequential arrangement of beds with characteristic primary structural assemblages suggests deposition under a transgressive phase, and overall retrogradational evolution of the storm-succession provides evidence in favour of faster downsagging of the basin floor. The Pb-Zn sulphide ore bearing sedimentary succession of Zawar records repeated downsagging and exhumation of the basin floor in the frame of continental rift tectonics. © 2005 International Association for Gondwana Research, Japan.
