摘要：

甘肃明水—黑鹰山一带是一个金铜镍铁（钨锡）三级成矿带。针对该成矿带华力西期金铜镍铁（钨锡）成矿作用，以含矿建造为基础，利用自然重砂数据，对该成矿带内含矿建造划分成50个地质单元进行自然重砂数据赋值，结合地质单元内矿床（点）数量及规模信息进行系列量化，对不同地质单元进行预测评价。共获得A级单元预测区5个，B级单元预测区12个，C级单元预测区16个，并经过初步对比发现，已知矿床（点）均出露于A级或B级预测区内，预测结果与该区已知矿床出露范围相当吻合，为矿产预测评价和找矿勘查工作提供参考资料。

Abstract:

Gansu’s MingshuiHeiyingshan area is a third class metallogenic belt with AuCuNiFe (WSn) mineralization potentials. This paper, based on the orehosting foundation, uses natural heavy mineral placer data to predict metallogenesis in Hersynian stage AuCuNiFe (WSn) mineralization of MingshuiHeiyingshan belt. According to the foundation distribution and geology, the belt is divided into 50 geological units for assignment values by natural heavy mineral placer data, which is integrated with number and scale of ore deposits or occurrences. Totally, 5 predicted areas of A class, 12 of B class and 16 of C class were obtained. Through comparison, it is found that the known deposits (occurrences) all located in both A and B class prediction area, which is in accordant with regional mineralization. This study provides usefully information for metallogenic evaluation and mineral exploration.
