Characteristic of red sandstone and its environment significance in Yunmengshan Formation of Yesoproterozoic in Yuntai Mount
Abstract：Gorge topography constituted of the red sandstone of Yunmengshan Formation of Mesoproterozoic is one of main landscapes in the Yuntai Mount World Geopark. Taken the red sandstone as the object, its sedimentary characteristic and environment are analyzed from the macro and micro viewpoints and the elemental compositions of dark purple and yellowish pink sandstone in the middle and upper Yunmengshan Formation are tested using SEM and EDS. Based on the above, the environment revealed by the sandstone is discussed in this paper. The result shows that the quartz sandstone of Yunmengshan Formation forms in the beach and tidal flat sedimentary environments and has a high compositional and textural maturity. The weight percent of element Fe in the cement of dark purple sandstone is obviously higher than that in the yellowish pink one, which is the effect acted together by lithosphere, hydrosphere, atmosphere and biosphere. This result has the important significance to study on the environmental characteristic in the Yunmengshan Formation stage.
