Early Yanshanian post-orogenic granitoids in the Nanling region?? Petrological constraints and geodynamic settings

Early Yanshanian magmatic suites predominate absolutely in the Nanling granite belt. They consist mainly of monzogranite and K-feldspar granite. There occur associations of early Yanshanian A-type granitoids (176 Ma—178 Ma) and bimodal volcanic rocks (158 Ma—179 Ma) in southern Jiangxi and southwestern Fujian in the eastern sector of the granite belt and early Yanshanian basalts (177 Ma—178 Ma) in southern Hunan in the central sector of the...
