This paper makes a review on several important aspects of geochemical prospecting work (both production and research work) performed by various units affiliated to Ministry of Geology and Mineral Resources, which include effectiveness of geochemical prospecting, geochemical prospecting for gold deposits, analytical instruments and methods, mercury vapor survey and advan ces in research work of geochemical prospecting. It describes in detail the breakthrough in the geochemical gold prospecting work:in the past ten years, using geochemical prospecting method, the Ministry of Geology and Mineral Resources has already discovered 277 gold occurrences and deposits, of which 62 are proved to be economic gold deposits. The numbers of silver, lead, zinc, tungsten, molybdenum, tin, mercury, antimony and barite deposits also obvious-sly incrense. The new advances in analytical methods for geochemical prospe cting have not only raised the efficiency of geochemical ore prospecting, but expanded the application fields of geochemical prospecting as well. Some successful case histories of geochemical ore prospecting are also given in this paper.
