烃、汞气体测量法常见干扰因素与消除

Common interference factors in hydrocarbon and mercury measurement and elimination method

烃、汞综合气体测量法是金属矿床勘查中刚刚被人们重视的地球化学勘查新技术,在应用该新方法技术时,常常会遇到四大类干扰因素,即:断层、土壤性质(包括土壤类型、C aO含量、地表有机质、pH值)、地表特殊景观(包括地貌类型、污染河流)、地下非矿信息源(包括火成岩、煤系地层),文章阐述了这四大类因素引起的干扰异常的识别和其影响特征以及对这些干扰因素的消除办法。

Comprehensive hydrocarbon and mercury gas measurement method is a new geochemical exploration technique which has just gained attention by geological circle. Four kinds of interferences would often be encountered, namely fault, soil characteristics （including soil type, CaO content, surface organic matter and pH value）, special surface landscapes （including geomorphic type and polluted stream）, underground non mineralization information source （including igneous rocks and coal measures strata） with this new method used in exploration. The paper describes by these four factors and their influencing characteristics method. discrimination of the interfering anomalies caused and summarizes the interfering factor elimination method.
