乌拉山含金矿脉赋存于新太古代乌拉山群高级变质岩区（变质程度以角闪岩为主，可达麻粒岩相），受控于乌拉山断裂构造带．区内出露了大桦背花岗岩体以及大量不同成因的长英质脉体．含金矿脉主要由中等—最大微斜长石、石英、黄铁矿和微晶自然金等矿物组成．对矿脉微斜长石有关信息作了Ｉ值信息量、对应－聚类及成因判别的分析．研究表明成矿作用可分为两个阶段，矿脉系岩浆热液成因．矿脉微斜长石钾长石组分的摩尔分数（ｘ（Ｋｆ））、有序度（Ｚ）和生成自由能（ΔＧ０ｆ）３个变量密切相关．矿脉含金性评价的矿物学标志为微斜长石有序度．
The Wulashan gold-bearing veins occur in the high-grade metamorphic rocks of the Neo-Archean Wulashan Group (the amphibolite-type metamorphism is mainly dominated by granulite facies) controlled by the Wulashan fault zone. The area shows the large birchback granite body and a large number of different causes of the British quartz body. The gold-bearing veins are mainly composed of medium-maximum microfacies, quartz, pyrite and microcrystalline natural gold and other minerals. I information about the amount of information about veins micro-plagioclase I, corresponding - clustering and genetic analysis. The study shows that the mineralization can be divided into two phases, the veins of the magmatic hydrothermal origin. The mole fraction (x (Kf)), order degree (Z) and free energy (ΔG0f) of the veined kapok feldspar are closely related to each other. The mineralogical sign of gold evaluation of veins is the degree of micro-plagioclase.
