| Abstract: | Neoproterozoic magmatism in the Yangtze Block of South China produced voluminous S- and I-type granites, and sparse A-type granites. The Daxiangling A-type granitic pluton is spatially associated with the Shimian I-type pluton at the western margin of the Yangtze Block. Both plutons have similar SHRIMP zircon U-Pb ages of～800 Ma and are slightly younger than the tonalite-trondhjemite-granodiorite (TTG) gneisses in the area. |
