摘　　要：石埠地区位于胶北隆起西南缘,区内北北东向断裂构造格架下发育的次级断裂带见金矿化带和低品位工业矿体。矿化带受区域性北北东向断裂构造控制,岩石具碎裂状构造,发育黄铁矿化、绢英岩化、绿泥石化等围岩蚀变,属岩浆期后热液脉状金矿床,成矿活动与元古代中-晚期和印支期两期次岩浆活动密切相关。成矿时代为新元古代和印支-燕山期两期次,古元古界粉子山群为初始矿源层。Shibu gold deposit is located in the southwestern margin of Jiaobei uplift. In Shibu region,the formation of gold mineralization and low grade industrial ore bodies is controlled by secondary faults,which are controlled by regional NNE fault structure. Fractured texture and wall-rock alterations such as pyritization,phyllic alteration,chloritization and other wall-rock alterations are widely developed.The ore-forming activity was closely related to the secondary magmatic activity in the middle-late Proterozoic and Indosinian.The metallogenic epoches are Neoproterozoic and Indosinian-Yanshan period,Paleoproterozoic Fenzishan group is the initial ore source layer.
