Analysis of uranium deposit diagenesis in Qianjiadian Sag of Songliao Basin

Songliao Basin was rich in oil and gas resources.This provided conditions for generation of sandstone uranium deposit in interlayer zone of oxidation.This paper analyzes the regional geological survey of Songliao Basin and the drilling samples of uranium deposit in Qianjiadian,expatiates the conditions of uranium mineralization and the impact of oil and gas on uranium deposit,and preliminarily determines the mineralization mechanism of Qianjiadian uranium deposit.As the first uranium deposit discovered in Songliao Basin,its mineralization and exploration may guide the exploration of other uranium deposits in the Basin.
