摘要
热穹隆构造是在一个构造活动(逆冲)带中,由沿走向发生的地壳差异性升降运动(走向波浪机制)产生的构造穹隆中的热(液)活动事件或是在这些部位由于中浅成岩浆岩的底劈式侵入而产生的热力性穹隆构造,它对金矿成矿的控制机理主要体现在适宜的浅层构造空间,贯深性构造通道及深源(下地壳)的岩浆岩和矿质热液源的有机统一。
In a structural active belt,the thermal domal structure is generated either due to the differentiate ascending and descending motion of the crust along the run which brings about thermal (fluid)activity event of structural dome or due to upward intrusion of medium supergene magmatic rock from bottom into these positions.Its control of gold deposit is mainly embodied in proper supergene structural space,penetrative tectonic passageway and deep magmatic rock (in lower crust) or source of thermal mineral fluid.The main orecontaining space is the fracture system of radiated (or bunchy)structure and ring structure produced by domal structure.
