摘要: 大庄子金矿是我国首次发现赋存于胶东变质岩中大规模韧-脆性剪切带内的蚀变岩型及石英脉型金矿床.金矿化与绢英岩化、黄铁矿化、硅化和碎裂岩化有关.矿体受韧-脆性剪切带、黄铁绢英岩化、晚元古代晚期角闪岩相变质岩的共同控制.矿石矿物组合以自然金-金属硫化物-架状硅酸盐为主的组合类型.矿床属于在韧-脆性剪切作用下，与含金量较高的下元古界荆山群变质岩的形成、演化有成因联系的蚀变、重熔、交代中温动力热液改造型金矿床.

Abstract: The Dazhuangzi gold ore,which depositted gold in the ductile-brittle shear zone, is altered rock type and quartz vein type discovered in China for the first time. The mining area is located in Lower Proterozoic Jingshan group on the eastern Yishu fault zone of the northwest upwelling area of the Eastern Shandong land mass,where developed a lot of faulted structures,magmatic activities and metamorphic processes.
