Abstract

Located on the west coast of the Pacific Ocean, Jiaodong gold concentration area is one of the world's famous gold deposit areas. Its unique metallogenic environment and metallogenic background are favored by geologists of all countries, multi-level and multi-disciplinary scientific research work has been carried out in this area, and good results have been achieved. Linglong gold deposit, located 20 km northeast of Zhaoyuan, Shandong, is a quartz vein type gold deposit. Its veins are controlled by Linglong and Batouqing fault, and vein groups are developed in the area, there are 36, 48, 47, 53, 55, 108 and vein groups 175, among which vein group 175 is one of the main large vein group in Linglong Gold Mine. With the continuous exploitation and utilization of the shallow resources in Linglong Gold Mine, the amount of gold resources kept in Linglong Gold Mine has decreased sharply, and the enterprises are facing the situation of serious shortage of resources. In order to prolong the service life of mines, it is urgent to enlarge the geological reserves of gold deposits and to increase the prospecting and prospecting efforts in deep areas. In this paper are sunnarized the geological and metallogenic backgroud and geologcal characteristics of the ore vein groups 175 and ore-control factor, occurrence pattern of ore body and ore types are analyzed and metalogenic pattern described. Based on prospecting works in which ore is encountered gold ore reserve 192.44×104t (332+333) and gold metal reserve 8.5t are predicted by geologic block method bellow -800m level beteen line 11-101.

胶东玲珑金矿175脉深部地质特征及找矿预测
胶东黄金富集区位于太平洋西岸,是世界著名的金矿区之一。其独特的成矿环境和成矿背景受到各国地质学家的青睐,开展了多层次、多学科的科学研究工作,并取得了良好的成果。玲珑金矿床位于山东招远东北20公里处,为石英脉型金矿床。区内脉群发育,有36、48、47、53、55、108脉群和175脉群,其中175脉群是玲珑金矿主要的大型脉群之一。随着玲珑金矿浅层资源的不断开发利用,玲珑金矿的黄金资源量急剧减少,企业面临着资源严重短缺的局面。为延长矿山的使用寿命,当务之急是扩大金矿床的地质储量,加大深部找矿力度。概述了该矿脉群175的地质成矿背景和地质特征,分析了控矿因素、矿体赋存模式和矿石类型,描述了成矿模式。在找矿工作的基础上,利用地质块体法预测了11-101线-800m以下的金矿储量192.44×104t(332+333)和黄金金属储量8.5t。
