新疆东天山典型金矿床成矿物质来源探讨

作者根据对新疆东天山典型金矿床的沉淀成矿环境、地球化学特征、稳定同位素特征等的系统分析和研究，论证了形成金矿床的硅质流体最初是一种以水为主要溶剂，以溶解态、胶体态氧化硅为主要溶质的高温高压(超临界态)溶液，其来源于地幔，是一种溶解了大量SiO2的地幔流体。而成矿元素主要来源于硅质流体上升运移过程中所经围岩，以致成矿物质来源具异源性。这对研究内生金矿床的成矿机制和成因有着十分重要的意义。

Origin of minerogenetic substance for typical gold deposits in east Tianshan, Xinjiang

According to the systems analysis and study of the minerogenetic surroundings, the geochemical characteristic, the stable isotope characteristic and so on for the typical gold deposits in East Tianshan, authors argue that the silicic fluid forming gold deposit is a kind of high temperature and high pressure (super-critical-state) solution, which contain abundant volatilizable components, take water as main solvent take dissolvable and colloid silica as main solute. It root in the mantle and is a kind of mantle fluid, which dissolve abundant silica. But the ore-forming elements mainly come from the wall rock through which the silicic fluid passes in the process of its move. So then the origin of the ore-forming substance has the feature of different root. There is very important significance for the study of the ore-forming mechanism and genesis of the gold deposit.
