对济源盆地承留三皇村的三叠系与侏罗系界线剖面地层沉积环境进行了研究 ,运用聚类分析等方法对各沉积环境中的元素共生组合关系及分布特征进行了分析。结果表明 ,在该剖面晚三叠世末期的谭庄组上部至早侏罗世的鞍腰组底部可划分出半深湖亚相、滨浅湖亚相、前三角洲亚相及冲积平原的河漫滩和泛滥盆地亚相等类型。在不同的沉积环境中 ,元素的组合关系、分布特征不同。除了元素本身具有不同的化学特征外 ,沉积环境的水体深度、与物源区的距离、沉积物的粒度大小、水体介质的化学性质 (盐度、pH值、Eh值 )等因素也决定着元素在沉积岩中的分布特征。
The depositional environment of Triassic and Jurassic stratigraphic stratigraphy in Sanhuang Village, where the Jiyuan Basin was inherited, was studied. Cluster analysis was used to analyze the symbiotic relationship and distribution characteristics of elements in each sedimentary environment. The results show that at the bottom of the Late Jurassic Tanzhuang Formation to the Early Jurassic Saddleback Formation at the end of the Late Triassic can be divided into semi-deep lake subfacies, shallow lake subfacies, the former delta subfacies and alluvial plain floodplain And the same type of sub-basin flooding. In different sedimentary environment, the elements of the combination of relations, distribution characteristics are different. In addition to the different chemical characteristics of the element itself, the depth of the water body in the sedimentary environment, the distance from the source area, the size of the sediment, the chemical properties of the water medium (salinity, pH and Eh values) Distribution in sedimentary rocks.
