[email protected] Abstract: Late Jurassic NE-trending A-type granitoids are widespread in the Shihang belt, South Citation: Lü, Z.-Y.; Ma, C.-Q.; Liu, Y.-Y.; Xiong, F.-H.; Wei, C.-X.; Chen, China, though their petrogenesis and geodynamic settings remain controversial. The Guiping M.-L.; Xue, G.-C.; He, Y.-S. Petrogenesis complex is located on the southwest margin of the Shihang belt. In this study, the petrography, major of the Jurassic Guiping Complex in and trace element geochemistry, whole-rock Sr-Nd isotopes, and zircon U-Pb geochronology of the the Southwestern South China Block: Guiping complex were investigated.
