在城门山铜矿系统开展了土壤壤中汞、热释汞、全汞的测量.结果表明,花岗闪长斑岩和破碎带上覆的土壤中具有明显的壤中汞气、热释汞的富集,土壤中汞气的主要源是深部的硫化物矿体.汞异常能够准确地反映出下伏矿体的赋存部位.土壤全汞因为本底汞的影响不能很好地反映矿化信息,利用土壤全量汞与热释汞含量的比值来抑制本底汞,突显热释汞,能更清晰地显示深部的矿化信息,是示踪深部矿化信息的有用的地球化学指标.

A systematic measurement on the soil mercury gas, thermal released mercury and the total mercury was developed in thecopper mine of Chengmenshan. The results showed that there were obviously enrichment of soil mercury gas and thermal releasedmercury in the soil above the granodiorite porphyry and fracture zones. The main source of the soil mercury gas is the deep sulfideore-body, and die anomaly of mercury gas correctly reflects the hosting location of the ore-body. The total mercury in soil can notgive the exact information as there is also background mercury. By the ratio of total mercury and thermal released mercury in soil wecan dilute the background mercury, thus it shall highlight the thermal releases mercury, and return information of deep mineralizationmore clearly. So it is a useful geochemistry index which can indicate the deep mineralization.
