众所周知,汞在地球化学探矿中是一个比较理想的通用探途元素。这是因为:首先,汞与很多种有色金属及贵金属矿床有着极其广泛的共生关系,可以在许多类型的矿床上出现异常含量;其次,由于汞具有极高的蒸气压,以及气态汞所固有的活动性及穿透能力,因此,汞的扩散迁移能力极强,足以在矿床周围形成范围很大的汞分散晕。然而,由于汞在地壳中的丰度很小,故区域化探样品中微量汞的分析,目前尚无合适的灵敏、准确、快速、简便的
It is well-known that mercury is an ideal universal exploration element in geochemical prospecting. This is because: First, mercury has a very extensive symbiotic relationship with many non-ferrous and precious metal deposits that can have anomalous levels in many types of deposits; and secondly, mercury has an extremely high vapor pressure and is inherent in gaseous mercury Mobility and penetrating power. Therefore, the ability of diffusion and migration of mercury is strong enough to form a large range of mercury dispersion around the deposit. However, due to the small abundance of mercury in the earth’s crust, the analysis of trace mercury in regional geochemical samples is currently not properly sensitive, accurate, rapid and simple
