广西倒翁沟金矿地质特征

Geological characteristics of Daowenggou gold deposit in Guangxi

倒翁沟金矿位于桂西北的右江沉积盆地中生界三叠系中,共圈出6个金矿体,矿体受层间破碎带和层位控制,具有两个主要矿化阶段,矿床属微细粒浸染型或卡林型金矿,矿区含矿地层含碳较高,岩石组合为泥岩、粉砂岩、少量细砂岩和灰岩等细碎屑岩组合,其中元素种类较多,认为岩石组合应属于黑色岩系的范畴。

The Daowenggou gold deposit is located in the Mesozoic Triassic system of the Youjiang sedimentary basin in northwestern Guangxi.There are 6 gold orebodies.The orebody is controlled by the interlayer fracture zone and layer,and has two main mineralization stages.The deposit belongs to the microgranular or Carlin type gold deposit.The ore bearing strata in the mining area are high in carbon,and the rock assemblages are mudstone,siltstone and a small amount of fine sandstone and limestone,in which there are many kinds of elements.It is considered that the rock assemblages should belong to the category of black rock series.
