摘　　要：锆石裂变径迹测年技术的运用厘定了舞阳凹陷古物源时代及方向;介形类优势分异度的定量计算,揭示凹陷浅湖成因类型;孢粉属性分析反映沉积时期的古气候变化特征;氯离子、碳酸根离子、生物标志化合物等研究分析出舞阳凹陷沉积时期的古水介质物化条件。Using zircon＇ s fission track age technique can determine the palaeo - source age and direction of Wuyang sag. Quantification calculation of the ostracod＇ s dominance diversity reveals shallow lake formation types. Analysis of sporopollen attribute indicates the changes of the palaeoclimate during the sedimentation time. Through the research on chloride ion, carbanion and biomarkers, the physico - chemical conditions of fossil water medium during sedimentation period of Wuyang sag can be analyzed.
