近些年,由于矿产资源不断的开发与利用,隐伏矿床的勘查引起了人们的高度重视,随着成矿理论和分析技术的发展,出现了很多新的地球化学勘查方法,并且在隐伏矿床的勘查中发挥着越来越重要的作用。这些方法主要有瑞典Kristiansson与Malmqvist(1984)提出的地球气纳微金属测量法(geogas),美国Clarke等人(1990)提出的酶提取方法,苏联地电地球化学方法(CHIM)(Shmakin, In recent years, due to the continuous development and utilization of mineral resources, exploration of concealed deposits has aroused people’s attention. With the development of metallogenic theory and analytical techniques, many new geochemical exploration methods have emerged, and in concealed deposits Exploration plays an increasingly important role. These methods include the geogas proposed by Kristiansson and Malmqvist (1984) in Sweden, the enzymatic extraction method proposed by Clarke et al. (1990) in the United States, the CHIM (Shimakin et al.
