| 摘 要： | 由于Ａｕ、Ｐｔ、Ｐｄ等元素分析测试技术的突破，使中国的贵金属地球化学勘查得到迅速发展。甘肃省自８０年代以来，金矿地球化学勘查取得了丰硕的成果。９０年代初，在研究改进Ｐｔ、Ｐｄ、Ａｕ化学－光谱法快速联测分析方法的基础上，在祁连山地区开展了针对金和铂族元素的区域地球化学勘查。工作结果，Ｐｔ、Ｐｄ、Ａｕ的报出率都达到了１００％，从而可靠地圈定了Ｐｔ、Ｐｄ、Ａｕ的地球化学异常。这一案例证明，地球化学勘查在寻找金和铂族元素矿产方面都是有效的

| Abstract: | With the breakthrough of analytical and detective techniques for such elements as Au,Pt,Pd etc.,a rapid development in Geochemical Exploration for precious metals has been made in China.Since 1980s,a great success in the Geochemical Exploration for gold in Gansu Province has been gained. In the beginning of 1990s,the Geochemical Exploration for gold and platinum group elements(PGE) was carried into effect in the Qilian Mountains on the basis of study and improvment of the Rapid Chemical Spectral Analytical Technique (RCSAT).The results showed that in this survey area all of these elements as Pt,Pd and Au were detected by one hundred percent ,thus reliable geochemical anomalies of which were delineated.The Geochemical Exploration was proved to be effective in exploring for both gold and PGE deposits. |
