Based on comprehensive geochronological, elemental and isotopic geochemical studies of the Qijianfeng granite in southern Tongbai-Dabie orogenic belt, the authors investigated the petrogenesis as well as the geodynamic settings and Mo mineralization of southern Tongbai-Dabie orogenic belt during Early Cretaceous. LA-ICP-MS zircon U-Pb dating yielded an age of (140±1) Ma for the Qijianfeng granite. The rocks exhibit adakitic characteristics, such as high SiO2 (72.88%-73.60%), low MgO (0.33%-0.36%), high Sr (620×10-6-642×10-6) content and high Sr/Y(107-111) ratios, low Y (5.65×10-6-5.95×10-6) and Yb (0.52×10-6-0.59×10-6) content, with negligible Eu anomalies. The rocks are enriched in K2O and depleted in Cr and Ni, and show enriched Sr-Nd isotopic compositions with initial 87Sr/86Sr and epsilon Nd(t) ranging from 0.7075 to 0.7078 and from -15.5 to -15.1, respectively. The rocks have zircon εHf(t) values of -19.9--13.2 with corresponding two-stage Nd and Hf model ages from 2.15 to 2.19 Ga and from 2.00 to 2.43 Ga respectively, suggesting that the magmas were derived from partial melting of ancient garnet-bearing amphibolites from the thickened lower crust. Combined with the previous studies, the authors propose two-stage magmatic activities and accompanying Mo mineralization during Early Cretaceous in southern Tongbai-Dabie orogenic belt. The first stage Mo-related rocks (>130 Ma) were derived from the partial melting of the thickened lower crust, while the second stage Mo-related rocks (< 130 Ma) were generated in a normal crustal environment. It is suggested that the southern Tongbai-Dabie orogenic belt experienced a tectonic transition from collisional compression to post-collisional extension, i.e., collapse, delamination and thinning of over-thickened orogenic crust and lithosphere during early Cretaceous (ca. 130 Ma).

Schematic tectonic map (a) and simplified geological map (b) of the Tongbai-Dabie orogenic belt (modified from Wang et al., 2014b)
Geological map of the Qijianfeng pluton (modified from Chen et al., 2018)
The photos of the Qijianfeng granite in the field and under the microscope
Representative cathodoluminescence (CL) images of zircon grains (a, the solid and dotted circles represent the analysis spots for U-Pb dating and Hf isotope, respectively. The U-Pb age and εHf(t) are shown on both sides of the slash), LA-ICP-MS zircon U-Pb concordia diagram (b) and weighted average age diagram (c) of the Qijianfeng granite
The diagrams of major elements for the Qijianfeng granite
Chondrite-normalized REE patterns (a) and primitive mantle-normalized spider diagrams (b) for the Qijianfeng granite. Normalization values for chondrite and primitive mantle after Sun and McDonough(1989)
Whole-rock ISr-εNd(t) diagram for the Qijianfeng granite
Zircon t versus εNd(t) diagram for the Qijianfeng granite
Sr/Y versus Y diagram (a, after Defant and Kepezhinskas, 2002) and (La/Yb)N versus YbN diagram (b, after Drummond and Defant, 1990) for the Qijianfeng granite. Symbols as for Fig. 5
