汞在地壳中高度分散,以及它的熔点低、热不稳定性、高温呈气态、蒸气压力高、结晶温度低等特点,决定它局部富集形成矿床而固有的特殊规律性。由于热不稳定,早期形成(同生或后生)的高汞层或矿床,往往被后期的各种地下热水(包括岩浆、构造等)所破坏转移或被改造富集。在改造迁移富集成矿的过程中,都要求岩石、岩块要有孔隙、裂隙或断裂、褶皱等张开部位,才能导致汞的活化和运移。这种“张”的部位不仅是通道作用,而且
Mercury is highly dispersed in the crust, and its low melting point, thermal instability, high temperature in the gas, high vapor pressure, low crystallization temperature, determine its local enrichment of the formation of the deposit and the inherent special laws. Due to thermal instability, the early formed (symbiotic or epigenetic) high-mercury layer or deposit is often destroyed by the various underground hot water (including magma, tectonics, etc.) in the later period and transferred or enriched. During the process of rebuilding and enriching mineralization, rock and rock are required to have pores, cracks or open fractures and folds to lead to the activation and migration of mercury. This “Zhang” site is not only a channel, but also
