详细论述了向阳山地区盆地盖层的沉积体系和沉积相特征，并结合测井曲线将其划分为冲积扇和冲积平原两大沉积体系及五类沉积相,对每一沉积相从岩性、沉积构造、测井曲线的形态以及粒度分布等方面进行了详细的研究;分析了沉积相的时空展布特点和层间氧化带在泉二段中的发育情况。最后从沉积相发育的角度分析了研究区层间氧化带砂岩型铀矿的前景。
Sedimentary facies and sedimentary facies characteristics of the caprock in the basin of Xiangyang Mountain are discussed in detail. According to the logging curves, they are divided into two sedimentary systems and five sedimentary facies of alluvial fan and alluvial plain. From each lithofacies, Sedimentary structure, shape of well log and particle size distribution. The temporal and spatial distribution characteristics of sedimentary facies and the development of interlayer oxidation zone in the second member of the spring are analyzed. Finally, the prospect of interlayer oxidation zone sandstone-type uranium deposits in the study area is analyzed from the perspective of sedimentary facies development.
