皖南新元古代花岗闪长岩地球化学特征及构造环境OA
Geochemical characteristics and tectonic setting of Neoproterozoic granodiorites in South Anhui Province
皖南新元古代花岗闪长岩沿祁门-歙县-三阳深断裂呈串珠状出露。本文在对其岩石学、地球化学细致分析的基础上，探讨了岩体的岩石成因和产出环境。皖南新元古代花岗闪长岩主要由石英、钾长石和斜长石组成，普遍含富铝矿物黑云母和堇青石，副矿物包括锆石、磷灰石、钛铁矿、独居石、磷钇矿、极少的磁铁矿等。地球化学分析数据显示，岩石总体具高硅、高钾、高铝和低钠、低镁、低钙的特征；岩石富碱（ALK=6．63％），高K2O／Na2O比值（1．33）。里特曼指数δ为0．8～2…查看全部>>
Neoproterozoic granodiorites in South Anhui Province are developed along Qimen-Shexian-Sanyang deep fracture and outcropped in the form of beaded veins. This paper studied petrographical and geochemi- cal characteristics of these granodiorites as well as its petrogenesis and tectonic setting. These granodior- ites mainly consist of quartz, potash feldspar, plagioelase, biotite and cordierite with minor accessory min- erals of zircon, apatite, ilmenite, monaz…查看全部>>
