摘　　要：通过对金矿形成的特殊性、金矿体变化的双重性及金矿探采对比的综合分析，总结出金矿预测及勘查的难度较之其它金属矿床要难得多，并由此引伸到隐伏金矿体的预测精度，目前较为流行的＂三定＂指标难以实现。因此，隐伏金矿体的预测不应以矿体做为预测对象，而应以＂矿化体＂做为预测对象。The comprehensive studies on gold minergentic characteristic and variation of gold orebodies symbol,the comparison of exploration and mining of gold orebody indicate that the prognosis and exploration gold deposits is much more diffcult than other metallic deposits.Which can be relation to the prognosis precision of bline gold orebodies.For which the mowadays current index of location,quantity and grade of reserves is difficulty to realize.Therefor,the prognosis objects must be“minerlaized body”rather than orebody.
