小兴安岭-张广才岭地区成矿金属元素分布特征及找矿靶区预测
|
摘要
为了揭示小兴安岭-张广才岭地区金属元素分布特征和突破找矿瓶颈,对区域成矿金属元素进行了聚类分析、因子分析和分形分析。结果表明,成矿元素组合为Pb-Zn-Mo-Ag-Au-Cd,可以作为找矿的指示元素,分形分析确定主成矿元素Pb-Zn-Mo-Ag的异常下限,基于Suffer和Mapgis软件建立元素异常分布图显示,异常区与已知大多数矿床套合,Pb、Zn、Ag异常高值带与其所在区域北西向次级断裂展布方向一致,与燕山早期花岗岩体也存在密切的关系。Au异常主要沿燕山晚期中酸性火山岩建造展布,这些元素异常高值带与地质体套合较好的区域均为成矿有利区。结合区域成矿规律共圈出找矿靶区4处。这一研究思路和方法为小兴安岭-张广才岭及其类似地区的找矿预测工作提供了科学依据。
The Xiaoxing'anling-Zhangguangcailing Region is an important metallogenic belt in northeast China. In order to reveal ore-metal distribution, we summarized the regional metallogenic regularity. R-type cluster analysis and factor analysis indicate that ore metal association is Pb-Zn-Mo-Ag-Au-Cd, which can be used as indicator for prospecting. The abnormal lower limits of main ore-forming metals could be determined by fractal analysis. Suffer and Mapgis software were used to establish geochemical anomaly distribution of these elements. The results show that the anomaly areas are associated with most of known ore deposits. The area with high abnormal values of Pb, Zn and Ag is consistent with NW trending secondary faults as well as with early Yanshanian granite, Au anomalies are mainly distributed along late Yanshanian intermediate-acid volcanic rocks. Combining with regional metallogenic regularity, 4 prospecting targets could be identified. The research methods in this paper could be used for future ore prospecting in the Xiaoxing'anling-Zhangguangcailing Region and other similar areas.
