大红山北铜多金属矿床地质特征及找矿方向探析

大红山北铜多金属矿床处于星星峡—明水金多金属成矿带上,具有良好的找矿前景,但由于区内工作程度低,多年来找矿一直没有很大突破。笔者以矿区地质勘查成果资料为依据,首先结合区域成矿地质背景,对矿区地层、构造、矿体特征、矿石特征等进行了全面分析。最后重点对矿床成因、找矿标志、找矿方向进行研究。文章通过深入研究后认为本区沿弧形构造线在岩体周边接触带部位及其附近的断裂构造裂隙中找矿是扩大区内远景的主要方向。上述分析对于区内进一步开展找矿工作、扩大资源储量有一定的参考价值。

Discussion on geological characteristics and ore exploration targeting of Dahongshanbei copper-polymetallic deposit

Dahongshanbei copper-polymetallic deposit, which is located in Xingxingxia-Mingshui gold-polymetallic mineralization belt, has a great prospecting potential. As for lack of exploration work, after many years, no significant prospecting breakthrough has been made. Based on the ore exploration results, this paper comprehensive analyzes the stratigraphy, structure, geological characteristics and ore geology, and mainly discuss on the ore genesis, prospecting symbols and exploration targeting. The most important exploration target in this area is within the contact of intrusive pluton and the structural factures nearby, which are along the arc shaped structural line. The analysis mentioned above has reference value for further exploration work and expanding reserve in the mineralization belt.
