SHRIMP zircon U-Pb dating of the Jiangshan-Shaoxing faulted zone in Zhejiang and Jiangxi

This paper reports SHRIMP zircon U-Pb ages (908~878Ma) of andisite and tuff of the Early Neoproterozoic Shuanxiwu Group on the northern side of the Jiangshan-Shaoxing faulted zone and discusses the tectonic background and regional stratigraphic correlation and tectonic evolution of the Jiangshan-Shaoxing faulted zone. The SHRIMP U-Pb ages and geochemical characteristics indicate the Early Neoproterozoic inner arc of the Shuanxiwu Group on the northern side of the Jiangshan-Shaoxing faulted zone. The SHRIMP U-Pb dating data obtained by the authors can provide new evidence for the correlation of metamorphosed strata in the Jiangshan-Shaoxing faulted zone.
