Abstract
Based on the integration of previous research achievement, this paper discussed the Lower Cretaceous Xinmingpu Group and uranium minerlization in Shazaoquan area of Badanjilin basin with results of field geological investigation as well as borehole verification. After analyzing the ore-contral factors, the uranium mineralization was believed to be controlled by sequence stratigraphic boundary, litho-facies, epiginetic oxidation. The favorite minerlization area should have relative stable structure and proper structural lift condition in the centre depression of the basin. The boundary of sequence Ⅳ/Ⅲ of Xin-minpu Group with the change in structural and depositional system and geochemical condition is the most important ore-control factor. The foreside of alluvial fan and midland also afford favourite lithology combination and space for uranium minerlization. Uranous granite afford the very beneficial uranium mineralizing condition for the sandstone-type uranium deposits. In general, Badanjilin basin have a good prospective.关键词
