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。
Gansu Mingshui - Black Hawk Mountain area is a gold copper nickel iron (tungsten-tin) tertiary metallogenic belt. According to the mineralization of gold, copper, nickel, iron and iron (W-Sn) in the metallogenic belt, based on the ore-bearing construction, the ore-bearing formation in the metallogenic belt was divided into 50 geological units by using the data of natural heavy sand Natural heavy sand data assignment, combined with the number of geological units in the deposit (point) and scale information for a series of quantitative analysis of different geological units for evaluation. A total of 5 A-level prediction zones, 12 B-zone prediction zones and 16 C-zone prediction zones were obtained. After a preliminary comparison, it is found that the known deposits (points) are exposed in the A or B prediction zones , The prediction result is in good agreement with the exposed area of the known deposit in the area, and provides reference materials for the prediction and evaluation of mineral resources and prospecting exploration.
