Sedimentary structures and environments of Lower Jurassic Anyao Formation, Jiyan, Central China

Abstract：The Lower Jurassic Anyao Formation in Jiyuan basin, western Henan province, central China, records turbidite sedimentation within a lacustrine turbidite system developed in a pull-apart basin. The primary sedimentary structures and stratification sequences have their private characteristics. Facies analysis suggests that this succession is formed in different sub-facies of turbidite sedimentary facies.
