| Abstract: | The LA-ICP-MS U-Pb dating technique was applied to the granitic rock in the Fuzhou compound rock mass that were producted from the mobile continent edge . The results show that the mean U-Pb age of the early Jiantian granodiorite is about 110Ma, the mean U-Pb age of the medium-term Danyang monzonitic granite and Fuzhou moyite is about 100-108Ma and the mean U-Pb age of the later period Kuaiqi miarolite is about 94Ma, belonging to the later Yenshan period. The time corresponds to the medium-late period of the early Cretaceous. It shows that the emplacement time about Fuzhou compound rock mass is from the medium-late period of the early Cretaceous to the early period of the late Cretaceous. The emplacement rock are from the mobile continent edge. Its magmatism time persistents 15Ma. |
