摘要
运用地质观测和统计分析研究,讨论了山东大尹格庄金矿床NWW向大尹格庄断裂的控矿作用。研究表明,大尹格庄断裂对矿化类型、强度和矿体产状都有明显的控制作用。NWW向大尹格庄断裂以北的Ⅱ号矿体群以金矿化为主,断裂南部Ⅰ号矿体群以银矿化叠加早期金矿化为特征。此外,研究还发现,大尹格庄断裂本身也存在金矿化,这对深化对该区矿床成因的认识和指导找矿预测都有一定的意义。
Ore-controlling effects of NWW trending faults in Dayin＇ gezhuang gold deposit, Shandong province, have been studied based on the geological study and statistical analysis. The results show that the Dayin＇ gezhuang Fault （DF） plays an obvious role in controlling the mineralizing styles, strengths and ore body occurrences. It is revealed that, the No. Ⅱ ore bodies north to the NWW trending DF are dominated by gold mineralization, while the No. Ⅰ ore bodies south to the DF are significantly superposed by following silver mineralization. In addition, gold mineralization has also been found in the DF itself. These studies may be of a great importance to the ore genesis and prospecting in this area.
