摘要
交通社金矿床位于柴达木盆地西北缘,矿体主要赋存于北西向及近东西向蚀变破碎带内,含矿地层为古元古界达肯大坂岩群片麻岩组,含矿岩性主要为强蚀变硅化褐铁矿化石英片岩、褐铁矿化碎裂岩。研究工作在矿区内圈出构造破碎蚀变带12条,圈定金矿体5条,矿体品位较高且规模较大。通过研究认为该矿床成因属于中-低温热液型矿床,矿床类型属构造蚀变岩型矿床,初步分析该地区具有良好的找矿前景和找矿潜力。
The Jiaotongshe gold deposit is located in the northwest margin of Qaidam Basin.The ore bodies mainly occur in the north-west trending and near east-west trending altered fracture zone.The ore-bearing strata are the gneisses formation of the Paleoproterozoic Darken Daban rock group,and the ore-bearing lithology is mainly strongly altered silicified limonite fossil quartz schist and limonitic cataclastic rock.The work showed that 12 structural fracture alteration belts and 5 gold orebodies have been circled in the mining area.The orebodies have high grade and large scale.In the research,the genesis of the deposit belongs to medium-low temperature hydrothermal deposit,and the deposit type belongs to tectonic-altered rock deposit.The preliminary analysis shows that this area has good prospecting prospect and prospecting potential.
