《"Lithofacies paleogeography and exploration significance of Sinian Doushantuo depositional stage in the middle-upper Yangtze region, Sichuan Basin, SW China"》
The Doushantuo Formation in the middle and upper Yangtze region mainly consists of detrital coastal sediments,carbonate platform deposits,continental shelf and restricted basin sediments,which can be divided into three sedimentary systems,six sedimentary facies,eighteen subfacies,and multiple micro-facies(Table 1).The clastic deposits are mainly concentrated in Z2d2 and Z2d4,and the carbonate deposits mainly in Z2d1 and Z2d3.Z2d1 and Z2d2 are sediments of transgression stage,Z2d3 was deposited at the highest sea level,and Z2d4 in the regressive sedimentary stage.The deposition of Doushantuo Formation constitutes a relatively complete transgression-high-regression sedimentary cycle.
