摘要
山东省青岛市平度市大庄子金矿区位于招远-莱州金成矿带西南边缘,矿区内构造受沂沭断裂带活动的影响,发育大量与其平行的NNE向压扭性断裂。矿区内四条大断裂形成了井字型构造体系。近几年通过对井字型构造体系的研究,在矿区北部洪山断裂带下盘区域取得的较大突破,发现了多条石英脉工业矿体,坚定了深部找矿的可行性。
Dazhuangzi gold mine area,Pingdu City,Qingdao,Shandong Province,is located at the southwest edge of Zhaoyuan Laizhou gold metallogenic belt.Influenced by the activity of Yishu fault zone,a large number of NNE trending compressive and torsional faults parallel to it are developed in the mining area.The four major faults in the mining area form a well shaped structural system.In recent years,through the study of the well shaped structural system,a great breakthrough has been made in the footwall area of the Hongshan fault zone in the north of the mining area,and a number of quartz vein industrial ore bodies have been found,which has confirmed the feasibility of deep prospecting.
