辽宁牛角沟金矿床地质特征及找矿标志

牛角沟金矿床位于华北地台北部东段金多金属成矿带的牧牛—东胜矿集区。通过地质测量、化探及探矿工程等一系列勘查手段基本查明了矿区地层、岩浆岩、地球化学异常、构造等分布特征,总结该区金矿成矿地质条件、矿床特征及找矿标志,为该区寻找新的金矿体及远景找矿评价提供依据;通过探矿工程揭露该区金矿体产于构造破碎带内,分布严格受构造控制,矿化带主要分布于石英脉及破碎带的裂隙中,矿化(体)产出与多期次多阶段的构造蚀变密切相关。

Geological characteristics and prospecting criteria of Niujiaogou gold deposit, Liaoning

The Niujiaogou gold deposit is located in Muniu-Dongsheng mineralization concentration area, eastern section of North China gold polymetallic metallogenic belt. The distribution characteristics of strata, magmatic rocks, geochemical anomaly and structures were basically identified by a series of integrated exploration methods including geological mapping, geochemical and test engineering works. The metallogenic geological conditions, mineralization, characteristics and prospecting criteria of the gold deposits in this area are summarized, which will provide the basis for the exploration of the new gold ore body and the evaluation of prospecting targets in this area. The exploration engineering work reveals that the gold bodies occur in the structural zone, and strictly controlled by structures. The mineralized zones are mainly distributed in the quartz veins and fractured zones, the formation of gold orebody is closely related to the multi stages of structural activities and alteration.
