本文讨论了小型脉状金矿床的地质和激发极化异常特征。在金矿勘查过程中，应特别注意低而稳定的异常，因为它们可能是小型脉状金矿床的反映。已知的脉状金矿床的探测证明了这一点。由于成矿条件的不同，金矿体既可以表现为低阻高极化体，也可以表现为高阻高极化体。电阻率法受地形影响较大。这些异常可以作为解释的参考信息，激发极化法受地形影响较小，是一种有效的勘查手段。
Geology and induced polarization anomaly characteristics of small veinlike gold deposits are discussed in this paper.In the course of gold ore exploration,special attention should be paid to low and stable anomalies in that they might be the reflection of small veinlike gold deposits,and this has been proved by the detection of known veinlike gold ore bodies.Due to different ore-forming conditions,the gold ore body may appear either as a low resistivity and high polarizability body or as a high resistivity and high polarizability body.The resistivity method is affected a lot by topography,and anomalies caused by small veinlike gold ore bodies cannot be easily separated from those caused by topography.These anomalies can serve as the referential information for interpretation.The induced polarization method is an effective means for exploring small veinlike gold ore bodies,because this method is less affected by topography.
