【摘要】 威海东部地区是金及多金属矿的有利成矿区。金矿化主要发育于新元古代荣成超单元的断裂破碎带中。银铜钼等多金属矿化主要发育于伟德山超单元的断裂破碎带或与古元古代荆山群的接触带中。荆山群是区内有利的矿化围岩,白垩纪青山群火山岩是铜矿化的有利层位。韧性剪切带及脆性断裂带等构造系统是含矿热液运移和富集的有利空间,控制着矿体的生成。该区具有较大的资源潜力和良好的找矿前景。本次研究是在野外调查和综合研究的基础上,通过分析控矿条件,研究矿床特征,总结成矿规律,为进一步找矿提出了建议。更多还原

【Abstract】 East part of Weihai city is a favorable area for forming gold and multi-metal deposits.Gold mineralization majorly developed in fractured fault belts of Neoproterozoic Roncheng superunit.Multi-metal mineralization,such as silver,cooper and molybdenum majorly developed in contacted zone of fractured fault belt in Weideshan superunit and Paleo-proterozoic Jingshan group.Jingshan group is favorable mineralization country rocks in this area.Volcanic rocks in Ordovician Qingshan group are favorable strata of cooper mineralization.Ductile shear belt and brittle fractured belt are favorable for ore-bearing thermal transformation and concentration which controlled the ore bodies forming.It has large resource potentiality and good ore-prospecting future in this area.On the basis of field survey and synthetic study,and through analysis of ore-controlling condition,deposit characteristics are studied,ore-forming rule is summarized,and suggestions for further ore prospecting are put forward in this paper.更多还原
