主 题:Sedimentology Mass movements Slumping Soft sediment deformation structures Jaisalmer Basin Jurassic
摘 要:A spectacularly exposed slump is described from a 120-m-long road cut between the villages of Kanod and Deva in the northeastern Jaisalmer Basin of Rajasthan,*** Upper Jurassic part of the sediments at the outcrop was formed in a near-shore setting and belongs to the Ludharwa Member of the Baisakhi *** 3-m-thick unit shows a number of asymmetric folds and thrust faults leading to an imbrication of partly lithified sandstone *** deformation structures allow the reconstruction of a movement towards the *** agrees well with the basin configuration that shows a deepening into this *** the determination of a specific trigger mechanism is difficult for soft-sediment deformation structures,an earthquake caused by synsedimentary tectonics in the basin seems to be the most likely explanation.
