Sedimentary Facies Characteristics of Yaojia Formation in Baiquan Area of Songliao Basin
This paper summarized the sedimentary facies types and characteristics of the Upper Creta-ceous Yaojia Formation in Baiquan area,Songliao Basin.It is considered that the Yaojia Formation in Baiquan area can be divided into upper and lower members.The upper member of Yaojia Formation has meander river facies and delta facies,while the lower member has braided river facies and delta fa-cies,and further be divided into 6 subfacies and 10 sedimentary microfacies.The braided river facies sand body of the lower member of Yaojia Formation has large thickness,good uranium anomaly has been found,which has good uranium metallogenic potential,and is a favorable area for uranium pros-pecting in the future.
