| 英文摘要 | Granitoid gravels are discovered from alluvial fan conglomerates, the base of Jurassic Fenghuangtai Formation (J(2)(2)), in the north margin of Dabie block and the south part of the Hefei Basin. These granitoid gravels make up 5%-10% of all gravels by volume percent. For the four components, K-feldspar, biotite, amphibole and whole rock divided from two selected granitold gravel samples, their Rb-Sr isotopes are measured, which gives two formation ages of granitoids: (428 +/- 20) Ma and (430 +/- 54) Ma, and means that the Early Paleozoic granitold intrusive rocks once existed in the Dabie Mountain provenances of Jurassic. The granitolds occur in the tectonic setting of post-collision uplift according to lithogeochemical discriminant analysis. |
