摘要
山东金岭玲珑花岗岩、郭家岭花岗闪长岩和脉岩构成了埠上金矿床的岩浆岩体系。玲珑花岗岩在矿区分布最广,郭家岭花岗闪长岩呈蓬状侵入玲珑花岗岩中。在矿区内,伴随着金矿脉有多起脉岩活动,脉岩与金矿脉的展布构造格式和形成时间有着紧密的依存关系。同时,在金岭地区花岗岩中利用脉岩作桥梁查明埠上金矿矿床成因,建立找矿模型。
Linglong granite,Guojialing granodiorite and vein rocks constitute magmatic rock system of Bushang gold deposit.Linglong granite distribute most widely in the region,invaded by Guojialing granodiorite resembling a cloak.There are several times vein-rock activity,going with gold veins activities.There is close dependency of structuredistribution format and forming time for gold deposit veins and vein rocks.At the same time,take vein rocks as a bridge,we find out the formation cause of Bushang gold deposit and build a prospecting model.
