广西苍梧县庆安矿区土壤地球化学特征及找矿潜力分析

Analysis of soil geochemical characteristics and prospecting potential in Qing'an mining area,Cangwu County,Guangxi

庆安金矿赋存于寒武系黄洞口组浅变质碎屑岩北东向构造破碎带中,与石英脉、黄铁矿关系较密切。与相邻的板山金矿床①有着相似的成矿地质背景和成因类型。区内开展了1∶1万土壤地球化学测量工作,圈定金异常带2处,异常带与构造破碎带呈北东走向相互套合,认为广西庆安Au异常与控矿断层关系密切,推测广西庆安异常具有寻找构造岩型金矿的找矿前景。

Qing'an gold ore is deposited in the north-east tectonic fracture zone of shallow metamorphic clastic rocks of the Huangdongkou Formation of the Cambrian system,and is closely related to quartz veins and pyrite.It has a similar metallogenic geological background and genesis type to the adjacent Banshan Gold Deposit(1).The 1∶10,000 soil geochemical survey work was carried out in the area,and 2 gold anomalous zones were delineated,and the abnormal zone and the tectonic fracture zone were intertwined in a north-east trend,and it was believed that the Guangxi Qing'an Au anomaly was closely related to the ore control fault,and it was speculated that the Guangxi Qing'an anomaly had prospecting prospects for finding tectonic rock-type gold deposits.
