摘要
该金矿床赋存于志留系茂县群浅变质的千脉岩中,受构造石英脉控制,是多次热液活动复合叠加形成的金矿床,属于中低温热液成矿,与碱交代作用关系密切。矿体呈脉状、薄脉状,具有膨胀收缩特点,呈舒缓波状延伸。蚀变千糜岩、石英脉、黄褐色铁帽是很好的找矿标志。
The Jindonggou Au deposit occurs as vein and veinlet in epimetamorphic phyllite of the Silurian Maoxian Group. It was formed by multiple hydrothermal activities and controlled by structural quartz veins. The gold deposit is a medium-low temperature hydrothermal one closely related to alkali metasomatism. Altered phyllite, quartz vein and pyrite are ore criteria of this gold deposit.
