摘要
矿区位于华北地台北缘，具有典型的受地层－岩体－构造控制的＂三位一体＂成矿特征。对矿区内隐伏金矿体的预测，应注意在岩体外接触带６ｋｍ范围内的北西向及东西向断裂构造的有利部位，要密切结合围岩蚀变、矿体的变化趋势、矿物及地球化学元素的垂直分带规律、地球物理激电异常等信息，最终提出隐伏矿体的预测准则。
The comprehensive studies show that the Nianzigou gold deposit located in northern border of North China Platform is a tipical joint functions of the stratigraphic rocks, the magmatic intrusion and the fault structure. Therefore, the prediction of concealed gold orebodies in Nianzigou ore district must pay attention to the composite spot of the north-west strike fault and east-west strike fault limited in the range of six kilometre, according to the distributive case of altered rocks, the variation of orebody sign, the vertical distribution of mineral and mineralizing elements, and the induced polarization sign of geophysical exploration etc.
