摘要
IP is an important method for mineral resources exploration,but it can only be applied in a few pivotal places because its difficult performance,and hence the information obtained from the survey area is very limited.The aim of this study is to find a simple and effective IP method with which we can get much valuable information form the survey area so as to improve the exploration effect.In the Yinan gold ore district,the authors applied the gradient sounding profile method,calculated 2D resistivity and obtained the IP model.The results show that the gradient sounding profile method is simple and effective.
