Abstract

Abstract

As a typical case of the Neoproterozoic magmatism in South Qinling, the Pailou porphyritic monzogranite exposed in the western margin of Wudang uplift. Zircon U-Pb dating on the granite yields an age of 667.2±3.5 Ma. The granite shows sub-alkaline and metaluminous affinities, with Na₂O+K₂O and A/CNK values ranging 8.31%-8.47% and 0.89-0.94, respectively. The monzogranite enriched in LILEs (i.e. Rb, K, U and Pb) and HFSEs (i.e. Nb and Ti), and depleted in Sr, P, Ti and HREE. Due to the high content of Zr+Nb+Y+Ce and ratios of 10 000 Ga/Al and FeO^T/(FeO^T+MgO), as well as characteristic minerals of hastingsite and ferropargasite, the Pailou monzogranite displaying A₁-type geochemical features. The zircon ε_Hf(t) values of the study rocks mainly vary from -1.8 to +1.5, indicating that the magma likely to have been sourced from mantle metasomatized by asthenosphere, OIB-like melts, with minor crustal assimilation. Based on modal calculations of trace elements, the fractional crystallization of plagioclase and pyroxene has been proposed during magmatic evolution. Integrating the data obtained from studies on geology, geochronology, geochemistry and isotopic compositions, we propose that the Pailou magmatism was the product of norogenic magmatism and formed in tectonic setting of a back-arc rift setting that probably developed in relation to slab tearing during continued slab rollback.
