An eogenetic paleokarst model controlled by multi-level sea-level:A case study of Shilongdong formation in Lower Cambrian,from the west Hubei and the east Chongqing to the west Hunan and Hubei,SW China
This study utilized field outcrops,thin sections,cathode luminescence,carbon and oxygen isotopes,and logging data to investigate the development model of paleokarst within the Shilongdong formation in Lower Cambrian,from the west Hubei and the east Chongqing to the west Hunan and Hubei area.The results show that the karst in the upper part of the Shilongdong formation is characterized by the dripstones developed within paleocaves,the paleoweathering crust with four zones(bedrock,weakly weathering zone,inten...
