Abstract The diamond orefield in Wafangdian of Liaoning Province is an important kimberlite-type diamond concentration area in China. The work degree, methods and achievements of previous geophysical prospecting are systematically analyzed so as to better apply geophysical prospecting for diamond deposits in the area. It is concluded that ground magnetic survey plays an important role in delineating shallow-surface kimberlite rock mass; audio magnetotelluric (AMT) survey and borehole geophysical exploration in the search for deep concealed kimberlite rock mass; while the 1:50 000 regional gravity survey and magnetotelluric profile survey, in the study of ore-controlling factors of diamond deposits. To sum up, geophysical prospecting is an important part of diamond exploration in Wafangdian orefield and reasonable combination of methods can solve corresponding geological problems.

Key words： kimberlite diamond deposit geophysical prospecting concealed rock body Liaoning Province
