    The study of the relation of geochemical elements of the Ordovician carbonate rocks in Tianjingshan mountain, Ningxia

    • 摘要: 宁夏天景山—米钵山奥陶纪马家沟组为一套台地碳酸盐岩沉积,米钵山组为一套台地前缘斜坡重力流沉积的碎屑岩夹泥质岩、碳酸盐岩。两组地层碳酸盐岩主要氧化物、微量元素和稀土元素具有明显的时空演化规律,地球化学特征既有独立性,又有相关性,与岩石宏观特征相一致,与沉积环境相关联

       

      Abstract: In Tianjing and Mibo mountains of Ningxia, the Ordovician Majiagou Formation consists of a suite of platform carbonate sediments, and Miboshan Formation a suite of clastic rock of gravity flow sediments on the margin of the platform, with argillaceous and carbonate rocks intercalated. The leading oxides, trace elements and REE of the carbonate rocks of the two formations exhibit the relationship of temporal and spatial evolution obviously Furthermore geochemical elements show both independence of their own and correlation with each other, which are identical to their macro features as well as related to their sedimentary environments.
