摘　　要：在综合分析已有资料的基础上,简要阐述了地球岩石圈的组成及地幔结构;详细介绍了尚峪火山岩的结构、构造、矿物成分及化学成分;系统性归纳了尚峪火山的喷发方式以及该岩体特有的形态特征;并结合区域地质构造,详细地研究了该处火山的形成机制,查明了岩浆活动与整个地壳运动在时间上和空间上都具有相关性,总结了该区火山岩的分布规律、岩浆岩类型和相关的矿产资源,为该地区开展地质找矿工作和研究此类矿床成矿规律提供了科学依据。With the comprehensive analysis of the old datas, the paper briefly described the composition of the Earth＇s lithosphere and mantle structure. Yet it described in detail the structure, construction, mineral composition and chemical composition of Shangyu volcanic, and systematically summed up Shangyu volcano＇s eruption patterns and morphological features characteristic of the rock. In conjunction with the regional geological structure, it studied in detail the formation mechanism of the volcanic area. The identification of the magmatic activity and the whole crustal movement are relevant in terms of time and space. It summarized the distribution of volcanic rocks in the area, magmatic rock types and associated mineral resources, which provided scientific basis for further exploration and ore-forming disciplines.
