| 摘 要： | 皖南3个著名的强过铝花岗闪长岩岩体,是晚元古代时期以洋壳(包括上覆沉积岩)为主要源岩,经部分熔融形成的侵入体。笔者认为广泛产于其中的岩石包体的成分多种多样,类型复杂,是不同时期岩浆作用的产物,是认识与之相关的寄主花岗岩成因的重要线索。

| Abstract: | There are three famous peraluminous granodiorite bodies which were formed by partial melting of oceanic crust (including overload sedimentary rocks)and scattered in South Anhui Province. Based on the study of field geology and petrography, as well as the data of petrochemistry, geochemistry and isotope analysis, it is concluded that the rock inclusions with various compositions and types widespreadly occurred in these granitoids are products of different periods of magmatism and an important clue to recognize the genesis of related host rocks. |
