| 摘 要： | 本文对晚二叠世—早三叠世岩浆岩的岩石化学、地球化学特征、与成矿的关系及岩浆活动形成演化环境进行了研究,较详细阐述了区内侵入岩受后期构造应力作用,岩石发育次生节理、裂隙。节理以走向北西向及北东向两组为主,其中北西向节理为较早期形成,北东向节理为较晚期形成,且较北西向节理发育,并切割北西向节理。岩石中矿物颗粒分布均匀,无定向组构特征的阐述。

| Abstract: | This paper is focused on the Late Permian - Early lrlasslc rocks Or igneous rOCKS, geochemical characteristics and mineralization of the formation and the developing environment of magmatic activity. Also describes the intrusive rocks under tectonic stress action, Soils developed derived joints and break. Joints to move towards the north west and north east trending mainly among North West to joints of the earlier form, the North East to joints as late stage form, and more North West to joint development and cutting NW joints. Rock mineral particles distributed uniformly describe the characteristics of non-directional fabric. |
