【摘要】 贵州水城地区二叠系玄武岩是峨眉山玄武岩东缘的重要组成部分,鉴于其特殊的构造岩浆活动事件及其资源环境响应,一直为国内外地质工作者高度关注。本文依托水城地区1∶5万区域地质调查资料,从时空产出特征、岩石学及地球化学特征及其成矿资源响应等方面对峨眉山玄武岩进行了系统的研究阐述,认为峨眉山玄武岩与铜矿、锰矿、稀土矿及钪锐钛矿的成矿作用有密切关系,为区域二叠系玄武岩喷溢事件及其成矿响应研究提供了新的资料。更多还原

【Abstract】 In Shuicheng area of Guizhou Province,Permian basalt is an important component of the eastern margin of Emeishan basalt,and In view of its special tectono-magmatic event and its response to resources and environment,geological workers at home and abroad have been paying close attention to it. Based on the data of 1 ∶50000 regional Geological survey in Shuicheng area,the Emeishan basalt from the aspects of spatial and temporal occurrence characteristics are systematically studied in this paper,petrological and geochemical characteristics and mineral resources response. It is considered that the Emeishan basalt is closely related to the mineralization of copper,manganese,rare earth and scandium anatase deposits,which provides new information for the study of regional Permian basalt events and their mineral resources response.更多还原
