摘要
文中钾长石脉型金矿,主矿体受近南北向张扭性断裂控制,形态为追踪式脉状,矿石工业类型为单一金矿石。主要脉石矿物为肉红色钾长石,载金矿物为五角十二面体黄铁矿及褐铁矿等。金为自然金,呈包体金、裂隙金和粒间金产出。直接找矿标志为含五角十二面体黄铁矿铁方解石钾长石脉。
The K-feldspar vein-type gold deposit fault zone tracing veins at south-north direction. in this report is controllea by a tenso-snear The industrial type of gold ores is of individual gold and the dominant gangue mineral is pink-colored K-feldspar. Minerals bearing gold is of pyritohedron pyrite and limonite, with which gold presents in native gold, enclosed gold, fissure-filling gold and intergranular gold. The ore-hunting indicator is of calcite-potassium feldspar veins containing pyritohedron pyrite.
