对金矿床地质地球化学和成矿流体及构造动力学研究认为，石英脉型金矿广泛发育围岩交代作用，在时间上遵循碱金属交代→Ｃａ、Ｆｅ、Ｍｇ中性交代→酸性交代的总体演化序列。与围岩的交代作用，沸腾作用引起的相分离和大气降水的加入所产生的混合稀释是成矿流体体系演化的主要途径，容矿断裂构造活动可划分为脆性破裂和韧脆性扩张两种动力学状态。成矿物质在非平衡和近平衡两种状态交替中分异结晶。流体演化与成矿动力耦合是形成金矿的主要机制。
Geological and geochemistry of the gold deposits and ore-forming fluid and tectonic dynamics studies suggest that quartz vein type gold deposits are extensively developed by the metasomatism of metasomatism, and follow the general sequence of alkali metal substitution → Ca, Fe, Mg neutral substitution → acid replacement Evolutionary sequence. Mixed with the surrounding rock, the phase separation caused by the boiling and the addition of the precipitation are the main ways of the evolution of the ore-forming fluid system. The ore-hosting fault tectonism can be divided into two kinds of dynamic force: brittle fracture and ductile and brittle expansion Learn state. Mineralization material in the non-equilibrium and near-balanced two state alternating crystallization. Fluid evolution and metallogenic coupling are the main mechanisms of gold formation.
