  • 地电化学提取法在青海西藏大沟北金矿区勘探中的应用……白生皓,魏国廷,拜红奎
  • 摘 要:西藏大沟北金矿区地处昆仑山东段青藏北特提斯成矿域,矿区内褶皱和断裂构造发育,成矿地质条件优越。通过已知地质剖面地电化学综合异常分析及相关地电化学测量工作,建立西藏大沟北金矿区异常评价标准,并圈定3类异常靶区共5处,其中Ⅰ类靶区主成矿元素金异常规模和强度大,各类异常明显且趋势基本一致,周边隐伏断层发育,成矿潜力较大。经槽探工程,Ⅰ-2和Ⅲ-2靶区异常验证效果良好。区内靶区异常与隐伏构造、侵入岩体走向一致,金矿成矿可能与构造活动和岩浆热液有关。

    Applicationof geo-electrochemical extraction method in the exploration of XizangdagoubeiGold District in Qinghai Province……Bai Shenghao,Wei Guoting,Bai Hongkui

    AbstractThe Xizangdagoubei Gold District is located in Tethyan metallogenic domainof the eastern part of Kunlun Mountains,where fold and fracture structuresdevelop and metallogenic geological conditions are superior.Based oncomprehensive anomaly analysis of one known geo-electrochemical profile andrelated geo-electrochemical measurement work,the paper established the anomalyevaluation criteria for Xizangdagoubei Gold District,and delineated 3 kinds ofprospecting target areas including 5 spots.The target area is with great mineralization potentialswhere Au anomaly are large scale and intense,all kinds of anomalies are obviousand coincide,and the surrounding concealed faults develop.The -2 and -2 target areas have great prospecting potentials verified by trenching.Thestrike direction of the target anomalous areas in the study area is roughlyidentical with that of concealed structures and intrusive rock mass,and golddeposit metallogenesis might be related to tectonic activities or magmatichydrothermal fluids.
