Beach bar genesis of the lower member of Xingouzui Formation in the southern slope zone of Jiangling sag, Jianghan Basin, and its controlling factors

Abstract

Abstract: Based on the analysis on sedimentary setting of the lower member of Xingouzui Formation in the Jiangling sag, the Jianghan Basin, and the comprehensive analysis with mud logging, coring and testing data, the sedimentary features and genetic model of shore shallow lake beach bar sands in the lower member of Xingouzui Formation in the southern slope belt of Jiangling sag and their controlling factors were discussed. It is considered that the beach bar sands are characterized by multi-phase development, vertical superimposition, lateral migration and contiguous distribution. They correspond to three types of genetic models, including lake wave, circulation and salt lake density current. The sedimentation of beach bar sands is controlled by paleo-base level cycle, paleogeomorgraphy and paleo-hydrodynamic force.

Key words: beach bar, genesis, controlling factors, lower member of Xingougzui Formation, Jiangling sag, southern slope belt
