Abstract
U-Mo deposit 460 is potential for prospecting volcanics-hosted U-Mo ore.Late volcanic hydrothermal mineralization overprints on the early porphyry mineralization.The deposit was formed in Late Cretaceous and Neogene.The remelted crustal materials,the acidic volcanics and sub-rhyolitic porphyry of the third member of Zhangjiakou formation are the U-source beds.Based on regional geological background,metallogenic setting and geological characteristics of the deposit the prospecting marks are highlighted and ore prospecting method is induced and summarized and the prospecting model is built for prospecting volcanics-hosted U-Mo deposits at north margin of the North China platform.
