Abstract

Abstract

Detailed researches on Zircon U-Pb chronology and geochemistry of the Dengshan Group in the eastern Jiangnan orogen have been undertaken in this paper in order to figure out the tectonic setting of the eastern Jiangnan orogen in the Neoproterozoic. SHRIMP zircon U-Pb dating of two samples yielded weighted mean ages of 855.5±8.2 Ma and 798±7.8 Ma, respectively. The sandstone rocks are mostly affiliated with a continental arc, in good agreement with the proposed back-arc basin scenario. These rhyolites display LREE enriched REE patterns, with positive ε_Hf(t) values, and has high values of FeOt/(FeOt+MgO) and Ga/Al, low contents of CaO and MgO, and it is enriched in Ba, Th, U and HFSEs, and depleted in Sr, P, and Ti, thus resembling A-type granitoids. These basalts are of tholeiitic basalt, and display ocean island basalt (OIB)-like geochemical signatures, with the enrichment of LREE and large-ion lithophile element relative to HREE. The bimodal volcanic rocks are suggested to be formed during post-collisional extension setting. Combined with the previously data from the Jiangnan orogen, we propose that the Jiangnan orogen leading to the assembly of the Yangtze and Cathaysia Blocks took place during 855-800 Ma. This was followed by breakup after the orogenesis which was triggered by mantle upwelling.
