Study and application of the partial extraction geochemical prospecting method for the uranium exploration in Changpai, north of Guangdong province, China

Partial extraction geochemical prospecting method was used to evaluate the uranium mineralization prospect and three uranium abnormal zones was outlined from north to south and joining together in the north of Guangdong. Satisfied prospecting results and several industrial uranium drilling holes have been obtained in the big uranium abnormal area by drilling. 4 geochemical prospecting indicators were developed for the exploration of granite-type uranium deposit by partial extraction geochemical prospecting method, which will play a more important role in the uranium exploration of deep buried ore and second prospecting space.
