长江中下游地区铁帽型金矿床的综合找矿方法

A Comprehensive Exploration of Gossan Type Gold Deposits in the Middle-Lower Yangtze Area

应用矿床地质学、元素地球化学、数理统计等多种方法对长江中下游地区铁帽型金矿床进行了评价。矿床地质分析是普查的基础,伴生元素地球化学指标的对比可以揭示金、银富集的内在联系,数理统计为诸多信息的高层次概括,而地形、地貌、重砂异常等可作为优选靶区的重要参考。

A comprehensive study on the evaluation of gossan type gold deposits in the Middle-Lower Yangtze area was made by using geological,geochemical and mathematical statistics methods.It is reoognized that:a general analysis of the geological setting of the deposits will set up several criteria for guiding the exploration;a correlation of geochemical indicators of associated elements will bring to light the internal relations of the enrichment of gold and silver;the vast amount of data and information collected can be highly condensed in order to have a clear understanding of their intricate relations;topographicaland geomorphic features,placer gold anomalies,etc.are important reference materials for target arealocating.A conclusion tallied with practical conditions can be drawn and it is useful to geologists in.gold ore finding.
