中天山九号超基性岩体位于尖山——阿拉塔格超基性岩带内。岩带呈近东西走向分布,长达几百公里,南北宽约几公里至十几公里。岩带中断续出露有七个超基性岩体群,岩体多达几十个。 九号超基性岩体位于岩带中段向南凸出的弧形构造顶端碱泉岩体群东侧。地理位置在新疆吐鲁番盆地南部中天山的戈壁滩上,属中天山复背斜的轴部。 超基性岩体的围岩主要由上元古代变质岩系组成。岩石类型有黑云母石英片岩、片麻
The Tiantaishan No.9 ultrabasic rock mass is located in the Jianshan-Alatag ultrabasic rock belt. Rock belt was nearly east-west distribution, up to hundreds of kilometers, north-south width of a few kilometers to ten kilometers. There are seven ultramafic rock masses intermittently exposed in the rock belt, with dozens of rock masses. The No.9 ultrabasic rock mass is located on the east side of the basement rock mass at the top of the arc structure protruding southwards in the middle of the rock belt. Geographic location in southern Xinjiang Turpan Basin Zhongtian Tianshan Gobi Beach, is a section of the Tianshan Mountains anticlinal axis. Surrounding rocks of ultramafic rocks mainly consist of the Proterozoic metamorphic rocks. Rock types are biotite quartz schist, flax
