吉林安图金星金矿区地质及矿床形成机理初探

Geologic feature and genesis of mineral deposit of Jinxing goldfield in Jilin Antu

金星金矿区位于吉林省安图县新合乡境内,其成矿域位于辉南—桦甸—和龙金(银)成矿带的东段。矿体受北西向韧性剪切带内次级断裂控制。矿体具分段富集、尖灭再现、膨缩现象。工业类型属蚀变岩与石英脉型金矿,其成因类型应为变质热液韧性剪切带型。

Jinxing goldifeld was located in Xinhe village of Antu County, Jilin Province. Its metallogenic domain located at the east of Huinan-Huadian-Helong gold （silver） metallogenic belt. Ore bodies are controlled by secondary faults in the NW-trending ductile shear zones. Ore bodies have stepwise-enrichment, end to end alignment of structures and expansive phenomena. It is alterated rock and quartz vein type the genetic type is hydrothermal metamorphism ductile shear zones type.
