福建紫金山地区地球化学勘查及找矿预测

GEOCHEMICAL EXPLORATION AND MINERAL PREDICTION IN THE ZIJINSHAN AREA,FUJIAN PROVINCE

本文介绍了作者１９９１～１９９３年期间在福建省紫金山地区进行的地球化学勘查工作和取得的部分成果，提出了对紫金山地区１／２０万区化扫面异常的分解、追踪、找矿靶区圈定和找矿预测等方面的有效方法。文中提出了紫金山地区的找矿标志和九个找矿远景小区，其中有的在普查钻孔原生晕研究中发现了工业品位的斑岩Ｃｕ、Ｍｏ、Ａｕ矿（化）体。据此，认为紫金山地区具有光明的找矿前景。

The results of geochemical exploration in the Zijinshan area of Fujian province are introduced. Some effective methods used for evaluating the regional geochemical anomalies and predicting targets are put forward including single stream sediment sample analysis and ’area--type" network rock survey. The results show that these methods have considerably effectiveniss and low cost in comparison with the conventional geochemical methods. Finally, the comprehensive prospecting criteria and 9 small prospecting districts are ditermined and some Cu, Mo, An--bearing POrphyries are revealed from them.
