黔西南金矿勘查地球化学30年:回顾与展望

勘查地球化学是快速寻找黔西南金矿的重要方法和技术手段.30年来,根据勘查地球化学圈定的金异常,为找寻肉眼难以识别的微细浸染型金矿提供了重要找矿线索和直接找矿靶区,并取得显著的找矿效果.黔西南金矿勘查地球化学的历史和研究表明,该区金的成矿地球化学条件优越,金地球化学块体内部结构及其套合的地球化学模式谱系预示尚有较大资源远景和找矿潜力.勘查地球化学需要结合地质、物探、遥感等方法,在新深度、新理论、新领域上进一步指导地质找金工作,才能不负时代所赋予的历史使命.

A REVIEW OF THIRTY YEARS' GOLD GEOCHEMICAL EXPLORATION IN SOUTHWESTERN GUIZHOU AND A PROSPECT FOR FUTURE WORK

Exploration geochemistry is an important method and technique for rapid seeking gold deposits from southwest Guizhou. In last 30 years, many important prospecting clues and targets of micro-disseminated gold deposits, which are difficult to distinguish by naked eyes, were provided according to exploration geochemical gold anomalies. It is suggested that there are predominant in geochemical conditions, more resource perspective and prospecting potential in inner structures of gold geochemical blocks and pedigrees of nested geochemical modeling from gold exploration geochemical history and investigation in southwest Guizhou, and the methods from geology, exploration geophysics, remote sense and et al. are needed to integrate with exploration geochemistry towards more seeking gold deposits and historical tasks.
