| 摘 要： | 本文对地矿部系统地球化学勘查(简称化探)的几个重要方面的生产工作和研究工作进行了评述,包括了化探找矿效果、金矿化探、化探分析仪器和方法、汞蒸气测量、化探研究工作进展等内容。着重介绍了金矿化探的突破性进展,地矿部十年来根据化探方法发现的金矿产地和矿床数已达277处,其中已查明62处为金的工业矿床。其它如银、铅、锌、钨、钼、锡、汞、锑、重晶石矿床的见矿数量也有明显增加。化探分析的新进展不仅提高了化探的找矿效果,而且扩大了化探的应用领域。本文还列举了一些成功的化探找矿案例。

| Abstract: | 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. |
