Sedimentary characteristics and lithofacies palaeogeography of the Late Sinian and Early Cambrian in middle Yangtze region;

The Late Sinian microbiolite and its phosphorus enrichment in Central Guizhou Province;

Based on the discovery of breakup uncomformity between the Lower Sinian Sidingshan Formation and the Fengtai Formation, the field features and geochemical evidence of the unconformity,and the Pb-Pb isochronal dating of silt mudstone interbeds from the Fengtai Formation being 620 Ma,the paper thought that the Fengtai Formation should be deposits of Late Sinian.

The Late Paleozoic-Early Triassic sedimentary characteristics in southwestern Fujian indicate that the Late Paleozoic-Early Triassic sedimentary construction is a typical passive continental margin sedimentary,and its continental slope faces to south,the line of Datian-Zhangping is equivalent to the low part of the slope at that time.

Sedimentary facies and palaeogeography during the Early Sinian and potential of the rhodochrosite deposits in northeastern Guizhou and its adjacent areas;

The Lower Sinian of Hunan Province has been divided into five sedimentary formation series and an ideal cross-section showing the Early Sinian tectonics and sedimentary formation of hunan Province has been restored.

During Early Sinian Nantuo Stage,three sets of incompleted glacial advance glacial recession sedimentary cycles composed of glacial drift and aqueoglacial facies developed in the eastern Yangtze Gorges.
