  • 青海省赛什腾山地区三角顶金矿区地质、地球化学特征及找矿方向……任文恺,晁海德,王生云,吴少锋,丁成旺
  • 摘 要:三角顶金矿床地处南祁连山南缘、柴达木盆地北缘,位于赛什腾山—阿尔茨托山Pb-Zn-Au-W-Sn(CuCo、稀土)成矿带赛什腾山成矿亚带。三角顶金矿床矿石类型主要为黄铁矿化、褐铁矿化石英脉型,次为黄褐色碎裂岩化、褐铁矿化蚀变花岗闪长岩型。含矿石英脉产出于花岗闪长岩节理、裂隙中,北西向构造为主要的控矿因素,围岩蚀变有青磐岩化、硅化、钾化,局部可见糜棱岩化。11万土壤测量显示,矿区内Au异常明显,共圈定组合异常13处,其中AP4AP5AP7AP9异常具有良好的找矿潜力。

    Geological,geochemicalcharacteristics and prospecting direction of the Sanjiaoding Gold District inSaishiteng mountain area,Qinghai Province……Ren Wenkai,Chao Haide,WangShengyun,Wu Shaofeng,Ding Chengwang

    AbstractThe Sanjiaoding Gold Deposit is located in the southmargin of southern Qilian mountain and north margin of Qaidam Basin,andSaishiteng mountain metallogenic sub-belt of Saishiteng mountain-Alzto mountainPb-Zn-Wu-W-Sn(Cu,Co and rare earth)metallogenic belt.The ore types inSanjiaoding Gold Deposit are mainly pyritiztation,ferritization quartz veintype,and secondarily cataclasitic and ferritization alteration granodiorite.Theore-bearing quartz vein occurs in the joint and fissure of granodiorite,and NW-trendingstructure is the main ore-controlling factor.The wall rock alteration iscomposed of propylitization,silicification and potash feldspathization,andlocal mylonitization.According to 110 000 soil survey,Au anomaly in the district isobvious.13 combination anomalies are delineated,among which the AP4,AP5,AP7,AP9combination anomalies have good prospecting potentials.
