新疆东昆仑祁漫塔格地区分布着一套上三叠统、喷发韵律明显的陆相火山岩和火山碎屑岩，它们起源于地下深部富集稀土元素的异常地幔，经历了一次从基性－中性－酸性的岩浆连续演化过程，是东昆仑构造演化转折期的产物。
4) Dupal anomal
Dupal异常地幔
5) upper mantle differentiation
上地幔分异
1.
Based on the detailed contrast between the chondrite normalized REE patterns and REE geochemical evolution law, this paper proves that the ore bearing fluid for the Carlin type gold deposits in the area mainly originates from the upper mantle differentiation, and that the crust (strata) matter partly contaminates the plutonic ore bearing fluid during moving from mantle to crust.
通过稀土元素配分模式的详细对比和地球化学演化规律的研究，论证了滇黔桂地区金矿的成矿物质主要来源于上地幔分异，但深部成矿流体在运移至地壳的成矿过程中不可避免地混染了部分地壳（地层）物质，从而在一定程度上掩盖了成矿物质的实质来
2.
Based on the detailed calculation of Pb isotope compositions, it is proved that the ore bearing materials and fluids of Carlin type gold deposits in the area mainly originate from the upper mantle differentiation, and that the crust (strata) matter partly contaminates the plutonic ore bearing fluid during transportation from mantle to crust.
