老挝色贡省TL金铅矿地质特征及成矿潜力分析

Geological Characteristics and Mineralization Potentiality of TL Gold Deposit in Sekong Province, Laos

老挝色贡省TL金铅矿位于波昆成矿区Samouay-VangTat金多金属成矿带上。通过遥感、地质调查、地球化学测量等手段快速锁定靶区,利用地物化综合剖面和激电测深进行异常查证及矿化蚀变信息提取,借助钻探对在寒武-奥陶系变质岩中发现的含金、铅等多金属构造片理化带进行工程控制。区内岩石、构造及蚀变矿化特征表明TL金铅矿是受构造控制的造山型金矿。该区及外围存在多条与之特征相似的含金构造片理化带,预示所在区域有着优越的成矿潜力。

TL gold deposit is located in the Samouay-Vangtat gold polymetallic metallogenic belt of Pokun metallogenic area in Se-gon Province,Laos.The metallogenic prospect area was quickly locked by means of remote sensing,geological survey,geochemical survey and other means.Anomaly verification and mineralized alteration information extraction are carried out by using the compre-hensive profile of geology,geophysics and chemistry and IP sounding.Structural foliated zone containing gold and lead were found and controlled by drilling in the Cambrian-Ordovician metamorphic rocks.The characteristics of rock,structure and alteration min-eralization indicate that TL gold deposit is tectonically controlled orogenic-type gold deposit.There are many similar gold-bearing structural foliated zones in the area and its periphery,which indicates that the area has superior metallogenic potential.
