塔斯特岩体由石英闪长岩、英云闪长岩、二长花岗岩和钾长花岗岩组成。岩石均具有高Ｎａ低Ｋ，Ｎａ２Ｏ、Ｆｅ２Ｏ３、Ｈｆ、Ｋ／Ｒｂ偏高，Ｋ２Ｏ、ＣａＯ、ＦｅＯ、Ｒｂ、Ｓｒ、Ｎｂ、ＲＥＥ、δ１８Ｏ、Ｏ、Ｒｂ／Ｓｒ明显偏低的特点。岩石化学和地球化学特征表明该岩体为形成于火山弧环境的“Ｉ”型花岗岩。岩体中Ａｕ、Ａｇ、Ａｓ、Ｂｉ、Ｃｕ等成矿元素明显富集，并与该岩体中金矿床、矿点的元素组合一致，说明该岩体与Ａｕ的成矿关系密切。岩体及其外接触带应为寻找金、铜矿产的有利部位。
Tarst rock is composed of quartz diorite, diorite, monzogranite and potash-bearing granite. The rocks are characterized by high Na low K, high Na2O, Fe2O3, Hf and K / Rb, and obviously lower K2O, CaO, FeO, Rb, Sr, Nb, REE, δ18O, O and Rb / Sr. Petrochemical and geochemical characteristics indicate that the rock mass is “I” type granite formed in a volcanic arc environment. The ore-forming elements such as Au, Ag, As, Bi and Cu are obviously enriched in the rock mass, which is consistent with the elemental assemblage of gold deposit and ore-point in this rock mass, indicating that this rock mass is closely related to Au mineralization. The rock mass and its outer contact zone should be favorable sites for finding gold and copper minerals.
