老挝川圹省孟坎县松凹铜金多金属矿地质特征及找矿前景

Geological Characteristics and Prospecting Prospect of Songao Copper-Gold Polymetallic Deposit in Mengkan County,Chuangkuang Province,Laos

老挝川圹省孟坎县松凹铜金多金属矿成矿条件良好,已经发现多个大—超大型斑岩型、矽卡岩型铜、金、锡多金属矿床。区域上中酸性闪长岩、花岗岩岩体沿北西向构造带侵入,活动时间长、期次多,在岩体转折部位和岩体分枝地段与碳酸盐类围岩和构造破碎带,具备形成矽卡岩型铜金矿床或蚀变岩型矿床成矿条件,矿区具备找矿远景和寻找铜、金矿的可能。无论是在矿区本部还是外围,通过勘查,有发现新的金矿化类型和增加铜资源储量的空间。

The Songao copper-gold polymetallic deposit in Mengkan County,Chuankuang Province,Laos,has good metallogenic conditions.Several skarn type and fracture zone type deposits in the contact zone between granite and limestone have been found,and several large-super large porphyry-skarn type copper,gold,tin polymetallic deposits have been found.The regional Forsyth neutral-medium acid diorite-granite complex intrudes along the north-west tectonic belt,with long activity time and multiple stages.In the transition position and branching section of the rock mass,the carbonate surrounding rocks and the tectonic fracture zone have the metallogenic conditions for the formation of skarn type copper-gold deposits or altered rock type deposits.The mining area has the possibility of expanding the prospect and looking for copper and gold deposits.Whether in the main body or the periphery of the mining area,there is room for discovering new types of gold mineralization and increasing copper reserves through exploration.
