本文通过安徽黄山地区花岗岩类岩石学特征的研究,提出太平—黄山花岗岩基是一个由印支期太平花岗闪长岩和燕山期黄山花岗岩组成的多期、多成因复合岩基,两者在岩石学特征方面存在极为明显的差别。通过综合对比,确认太平花岗闪长岩属于同熔型花岗宕;黄山花岗岩属于改造型花岗岩。根据地球物理资料,作者认为这种多期、多成因复合花岗岩基出现于莫霍面隆起和莫霍面拗陷的过渡地区,与深大断裂有空间的联系。
Based on the study of granitoids petrological characteristics in Huangshan area, Anhui Province, this paper proposes that the Taiping-Huangshan granite basement is a multi-stage and multi-genesis complex rock foundation composed of Indosinian Taiping granodiorite and Yanshanian Huangshan granite. There are significant differences in petrological characteristics. Through comprehensive comparison, it is confirmed that the Taiping granodiorite belongs to the same melted granite dam. Huangshan granite belongs to the remolded granite. According to the geophysical data, the author believes that this multi-stage and multi-genesis complex granite base appears in the transition area between the Moho uplift and the Moho downhole and has a spatial connection with deep faults.
