Detrital Zircon Geochronology and Directional Structures of Cambrian Sediments in Jiangshan of Zhejiang Provence and Their Palaeogeographic Significance
In this study,the age spectra of detrital zircons and sedimentary directional structures are used to investigate thepaleogeographic features,especially the paleogeography in east Cathaysian Block.The dating results of detrital zircons from clasticinterlayers of the Yangliugang Formation in northern Jiangshan of Zhejiang Province,which lies on the southeastern margin of theYangtze Block,show that the ages range from 515 Ma to 3340 Ma,with a major peak at 828 Ma and secondary peaks at 727 Ma and916 Ma in the ...
