摘要
小佟家堡子金矿床位于辽吉古元古代裂谷中部的青城子矿集区内,矿体赋存于辽河群大石桥组上部碳酸岩与片岩的过渡带,容矿岩石为黑云变粒岩和硅质岩,矿体受层位控制,呈层状、似层状产出;矿石中的金以不可见金为主,含量与黄铁矿、毒砂关系密切。对矿石组构特征研究表明,该矿床形成既与沉积作用有关,又遭受后期变质变形及热液的叠加改造,矿床为热水沉积—变质热液改造成因。
Xiaotongjiapuzi gold deposit exists in interlay belt of the crest of Dashiqiao series, Liaohe group. The ore-containing rocks are mainly biotite granulite and silicalite. The orebody is controlled by interlayer slip tectonics and the orebody presents banding or likelihood stratification. The gold in ore is principally invisible. Its gold content is closely related to pyrites and arsenopyrite. The formation of the deposit is related to action of deposition, as well as afterward metamorphic deformation and hydrothermal superimposed reconstructing.
