摘要

The Zigui Basin is a well-preserved Jurassic sedimentary basin that lies in the eastern section of Daba Mountain tectonic belt. Some fossils preserved in limestone can be found as gravels, and this indicates deposition proximal to source area. The thinner conglomerate deposited in the meandering river is distributed around south and southeast of the basin. The restored paleo-currents and provenance analyses show that sediments were mainly from the Shennongjia area at the early stage. Sedimentary filling characteristics and the northwestern margin fault of the basin with sinistral strike-slip, as well as a number of south-dipping reverse faults on the north of basin-margin show that the Zigui Basin was controlled by these faults.
