云梦山组红色石英砂岩形成的峡谷地貌是河南省云台山世界地质公园的主要景观之一.以云台山地区云梦山组红色石英砂岩为研究对象,从宏观和微观角度对石英砂岩的沉积特征及沉积环境进行分析,并利用扫描电子显微镜和能谱仪对云梦山组中上部的暗紫色和肉红色石英砂岩进行了元素成分分析,在此基础上探讨了其揭示的环境意义.研究结果表明,云梦山组石英砂岩形成于滨海海滩-潮坪环境,具有较高的成分和结构成熟度,暗紫色石英砂岩胶结物中Fe元素的含量明显高于肉红色石英砂岩中的含量,该现象是岩石圈-水圈-大气圈-生物圈共同作用的结果.该研究对于云梦山组沉积时期的环境分析具有重要意义.
The canyon landscape formed by the red quartz sandstone in Yunmengshan Formation is one of the main landscapes of Yuntaishan World Geopark in Henan Province.The red quartz sandstone of Yunmengshan Formation in the Yuntaishan area is taken as the research object and the deposition of quartz sandstone is macroscopically and microscopically Characteristics and sedimentary environment of the Yunmeishan Formation, and analyzed the elemental composition of the dark purple and meat red quartz sandstone in the upper part of the Yunmengshan Formation by using scanning electron microscopy and energy dispersive spectroscopy. On the basis of this, the environmental significance of the revelation was discussed. The results show that the quartz sandstones of Yunmengshan Formation formed in coastal beach-tidal flat environment with high composition and structural maturity. The content of Fe element in dark purple quartz sandstone cements is obviously higher than that in meat red quartz sandstone. Is the result of the interaction of lithosphere-hydrosphere-atmosphere-biosphere.The study is of great significance for the environmental analysis of the Yunmengshan Formation during its depositional period.
