Regional Metallogenic Characteristics and Prospecting Potential of Uranium Deposits in Southwest Area China

Abstract

Abstract:The uranium resources prospecting started in 1955，xx uranium deposits has been prospected，and 5 uranium ore fields has formed in southwest area. According to the regional uranium metallogenic characteristics and the class of tectonic units in control region，combining concentration degree of uranium deposits，uranium mineral occurrence and mineralized spot, the region can be divided into five uranium metallogenic belts including Gangdise-Tengchong， Sanjiang，northwestern Sichuan，northern Sichuan，central Guizhou and four uranium metallogenic prospective belts including Gangdise, Qamdo, Changtai-Daocheng and Xikang-Yunnan axis.It is considered that the uranium geological metallogenic conditions are favorable besed on researches onmetallogenic characteristics of main uranium metallogenic belts. The breakthrough direction is to expand old mining areasand toopen up new bases.
