摘要: 新坪金矿地处广西大瑶山成矿带的东部,是桂东南地区一个较为典型的构造破碎蚀变岩型金矿。调查发现:矿区内金矿体(金矿化)主要赋存于寒武系黄洞口组中,部分金矿体(金矿化)赋存于花岗斑岩与寒武系硅化砂岩接触破碎带以及花岗斑岩体内,近EW向、NE向的次生断裂和裂隙是主要的容矿构造,而金矿化强度与硅化、黄铁矿化、绢云母化关系密切。根据新坪金矿的矿床地质特征、成矿规律和化探异常进行综合分析,圈定了矿区内2个成矿远景区及6个找矿靶区。

Abstract: The Xinping gold deposit, located in the eastern part of Dayaoshan metallogenic belt in southeastern Guangxi, is a typical altered rock type gold deposit. Controlled by EW and NE secondary faults, the ore bodies mainly occur in fracture zones which formed in Cambrian strata, or in contacting belt between strata and graniteporphyries, or in graniteporphyries. The gold mineralization has close relationship with silicification, pyritization and sericitization. Based on geological characteristics of the deposit, metallogenic regularities and the geochemical anomalies, we put forward six prospecting targets in two prospective areas.

Key words: Dayaoshan metallogenic belt, altered rock type gold deposit, metallogenic regularity, metallogenic prognosis, Xinping gold deposit, Guangxi
