摘　　要：新疆达坂城一带岩浆活动并不强烈,形成较少的辉长闪长岩侵入体。其主要特征、特征参数及相关图解综合反映为下地壳局部熔融改造成因,形成于挤压构造环境。这对邻区该类岩石的相关研究具有一定参考及对比意义。Magmatic activity is not strong in Dabancheng area, and it is formed ofless gabbro diorite intrusive body. Its main characteristics, characteristic parameters and related graphic comprehensive reflection for lower crust partial melting transformation causes, formed in the extrusion tectonic environment. The adjacent area the rock related research has certain reference significance and contrast.
