粤北张屋坪锑矿点的矿床成因与找矿前景浅析

Analysis on genesis and prospecting prospect of zhangwuping antimony deposit in north guangdong province

粤北地区矿产资源丰富,特别是粤北曲仁构造盆地,属南岭成矿带的核心区域,区内曾发现多个大中型金属矿床,小型矿床更是不计其数。通过分析张屋坪矿区的区域及矿区地质背景,在此基础上,对矿区的矿体特征和矿石特征进行研究,粗略分析其成矿机理,总结深部找矿经验。张屋坪锑矿点与区内赤老顶锑矿床同属于一个成矿带,并且具有相似的成矿地质条件。根据矿床地质特征,沿矿床走向及倾向的延长方向、矿床两侧的次级断裂构造以及矿区深部,均具有十分重要的找矿意义。

The northern part of guangdong province is rich in mineral resources, especially the quren tectonic basin in the northern part of guangdong province, which is the core area of the nanling metallogenic belt. Based on the analysis of the regional and geological background of zhangwuping mining area, the ore body characteristics and ore characteristics of the mining area are studied, the metallogenic mechanism is roughly analyzed, and the deep prospecting experience is summarized. The zhangwuping antimony deposit and the chlaoding antimony deposit belong to the same metallogenic belt and have similar metallogenic geological conditions. According to the geological characteristics of the deposit, the extension direction of the strike and inclination of the deposit, the secondary faults on both sides of the deposit and the depth of the mining area are of great significance for prospecting.
