| 摘 要： | 激发极化方法一直是有色金属矿产勘查的主要手段,国内大多使用时间域激发极化方法,相位激发极化法应用较少。相位激电法采用选频测量,抗干扰能力相对较强,近些年在有色金属矿产勘查中一直使用相位激电测深方法,取得了较好的实际应用效果。在使用中,根据实际情况选用偶极-偶极或单极-偶极测量装置,其中偶极-偶极测量装置主要用于普查阶段,单极-偶极装置采用常规高密度电法的布极方式,主要用于详查阶段。这里以具有代表性的高阻高极化、低阻高极化矿体上的应用结果为例,说明偶极-偶极和单极-偶极装置相位激发极化测深的应用效果,以及在实际找矿工作中的作用。

| Abstract: | The Induced polarization method has been the main method used in non-ferrous mineral exploration.In China,the time domain induced polarization method is mainly used,while the phase induced polarization method is seldom used.The phase induced polarization method adopts selective frequency measure,providing high interference resistance.The phase induced polarization method has been used in non-ferrous mineral exploration over recent years with satisfied results being obtained.In practice,dipole-dipole or pole-dipole measurement devices are selected according to the specific conditions with the dipole-dipole device mainly used in reconnaissance and the pole-dipole device,which adopts the pole arrangement of the conventional high density electric method,and is mainly used in detailed investigation.The application of the dipole-dipole and pole-dipole devices to depth measurement through phase induced polarization is illustrated in the representative high resistance high polarization and high resistance low polarization ore bodies. |
