Abstract: In order to further expand the achievements of diamond exploration and submit newly added diamond resources, the authors in this paper take kimberlite-type diamond primary ore in Wafangdian of Liaoning Pro-vince as the key research object to summarize the prospecting model by applying geophysical, river system heavy sand, geochemical, remote sensing and three-dimensional geological methods. The combination model of three prospecting methods with short period and economy was established, including heavy sand method + high precision magnetic survey on the ground + engineering exposure (geochemical exploration), airborne geophysical prospecting + high-precision magnetic survey on the ground + heavy sand + engineering exposure (geochemical exploration), remote sensing + heavy sand + high precision magnetic survey on the ground + geochemical exploration + engineering exposure prospecting method. This work has important guiding significance for diamond exploration in Liaoning Province in the future.
