摘　　要：本文介绍了广西老厂矿田的区域地质,总结了同生断层矿田标志性地质特征及其与成矿的关系。该区旺塘村-兴坪断裂、Sidi-龙门边界断裂、全会凉伞顶部断裂和老厂-宝塔龙断层所断裂的地质特征与同生断裂的一般地质特征一致,因此推断这四条断裂为同生断层体系,岩相古地理、构造、沉积、地质特征,该区域岩石和矿石与标准喷流沉积铅锌矿床非常一致,表明该区域可能存在受同生断层系统控制的层状和准层状构造,尤其是在老厂矿田西部和潮汐场的坳陷区。This paper introduces the regional geology of Laochang ore field in Guangxi,and summarizes the symbolic geological characteristics of syngenetic fault ore field and its relationship with mineralization.The geological characteristics of the wangtangcun Xingping fault,Sidi Longmen boundary fault,tongliangumbrella top fault and LAOCHANG baotalong fault in this area are consistent with the general geological characteristics of syngenetic faults.Therefore,it is inferred that these four faults are syngenetic fault system with lithofacies,paleogeography,structure,sedimentation and geological characteristics.The rocks and ores in this area are very consistent with the standard exhalative sedimentary lead-zinc deposit,It indicates that there may be layered and quasi layered structures controlled by syngenetic fault system in this area,especially in the west of Laochang ore field and the depression area of tidal field.
