Abstract: Induced Polarization (IP), with 100~200 m exploration depth currently, is an effective method for metal deposit survey. Since most shallow metal deposits have been discovered, the deep ones have to be searched for. So, deep IP must be studied. In this article, the following key problems relating to improving signal-to-noise ratio are discussed such as selection between time domain system and frequency domain one,powerful IP dual-frequency observation system, deep IP field configurations, removal of electromagnetic couple effect. The discussion is helpful to undertake research of deep IP.
