摘要 

本文是地质矿产部自1978年~1987年十年来组织开发金矿化探工作的一篇总结性和评述性文章。该部十年来采用化探方法发现的金矿产地共272处,其中现已查明为工业矿床者62处。总结的主要经验有:①努力实现用痕量金作指示元素来寻找金矿床②金矿化探工作中应坚持“区域展开,重点突破”原则③全矿化探普查的选区应以1:20万区域化探中出现的金异常为依据④在金异常检查和详查中采用痕量金的“现场分析”方法。对于金矿化探在我国今后的发展趋势作者提出如下看法:①金及有关元素的区域性地球化学图件的编制和研究预期将加速开展②痕金分析方法和技术将获得进一步发展,并提出应研究和开发一种可以同时测定Au、Ag、As三种元素的现场分析方法和技术③金矿化探的采样代表性问题的研究将被列入议事日程④金异常的检查和研究将普遍开展⑤厚层覆盖地区金矿化探方法的研究将获得重要进展。

Abstract

This paper gives a summarization and review on geochemical gold prospe-cting work in1978-1987 organized by Ministry of Geology and Mineral Resour-ces. Using geochemical prospecting method the Ministry. has discovered in thepast ten years 272 gold occurrences,. of which 62 are proved to be industrialgold deposits. The main experience gained is as follows: (1)Every effort shouldbe made to use trace gold as the indicator element in gold prospecting; (2)in geochemical gold prospecting work, one should stick to the principle of "carrying out the work on a regional scale and making breakthrouth at mostfavorable points"; (3) the choice of areas for geochemical gold recounaissanceshould be based on gold anomalies detected in1:200,000 regional geochemicalprospecting;(4) the on-the-spot trace gold analysis method ought to beadopted in follow-up for gold anomalies. Regarding the future developmenttrend of geochemical gold prospecting in China, the authors puts forward thefollowing views: (1) The compilation and study of regional geochemical mapsfor gold and related elements are expected to be accelerated; (2) the analy-tical method and technique for trace gold will be further developed, and it issuggested that an on-the-spot analytical method and technique for simultane-ous determination of Au, Ag and As should be worked out; (3) the study ofrepresentativeness in geochemical gold sampling wil1 be put on the agenda;(4) the study and follow-up for gold anomalies will be extensively carriedout; and (5) important advances will be made in the research of geocbemicalgold prospecting in thick overburden areas.
