Characteristics of Unconformity-Related Deposit and Prospecting Direction in Lüchun-Jiangcheng Area of Yunnan

Since the unconformity-related deposit was put forward, a great breakthrough has been made in prospecting this kind of deposit both at home and abroad, with a number of super-large scale uranium deposits relating to the unconformity surface having been found in Canada, Aust ralia, and so on. Being large in scale, high in grade, and not controlled by other structures, the unconformity-related deposits attract much attention of geologists. On the basis of summarizing the charact eristics of the unconformity-related deposits, we further studied the form ation mechanism of the unconf ormity-related deposit and discussed the characteristics of geology, mineralization, alteration, and special low-to-moderate-temperature element assemblage in Lchun-Jiangcheng area and hold that the area has a good fuure infinding the unconformity-related deposit.
