摘要
重点论述了新疆阿合奇县托什干河上游地区地质构造格架,在前人按照大洋和大陆岩石圈两种构造体制演化形成的板块构造带为原则划分的Ⅰ、Ⅱ级构造单元的基础上重新划分和命名了研究区内的二个Ⅲ级构造单元。再根据沉积建造、岩浆作用、变形特征、变质程度、变形期次等差异进一步划分出了六个Ⅳ级构造单元。根据实际资料对主要构造单元的基本特征进行详细概括和总结,并对研究区构造变形相和大地构造相作了初步研究和分析,同时对研究区地质构造发展演化史进行了较合理恢复。
This paper focuses on the geological framework of Aheqi,based on the previous research of Ⅰ,Ⅱ grade tectonic units which were in accordance with plate tectonic belt experienced two kinds of tectonic evolution of the lithosphere of the oceanic and continental plates,redivided and renamed the two iii tectonic units in this study.Then according to the differences of deformation characteristics,sedimentary formation,magmatism and metamorphic degree and deformation,it was divided into six the fourth tectonic units.And then we can survey and describe the characteristics of the main structural feature based on the actual data.And we had made the preliminary research and analysis on tectonic deformation facies,tectonic deformation sequence and tectonic facies and recovered the development and revolution of the geological structure in reasonable in the study.
