摘要
夹皮沟主剪切带位于太古宙中朝古陆板块与元古宙蒙古海板块之间的缝合线上,受北西向的富尔河—古洞河岩石圈断裂带控制。金矿床多数产在主剪切带中,与成矿有关的中酸性侵入杂岩体多为深熔花岗岩浆产物,容矿构造往往为韧性剪切带或脆性构造破碎带内的片理化带。金矿床为少硫化物石英脉型。该带具有优异的成矿条件,是吉林省金矿主要的资源。
Dense Au deposit zone is located in the suture between Archaeozoic Zhongchao ancient land plate and Proterozoic Mongoliasea plate,controlled by NW Fuerhe and Gudonghe lithosphericfractures.Au ores are generally enriched in the edges of abovementioned plates,intermediate-acid intrusive complex related to ore-forming resulted from anatectic granite magma.Hoststructures are usually ductile shearzones or schistosity zones in brittle fracture zones.Au ores dominantly belong to sulphide-lacked type,and then to tectonic altered rock type.The dense Au ore zone possesses excellent metallogenic conditions,is the main prospect area of Au deposits in Jilin province.
