摘要:
长期以来学者们一直认为湘西北四都坪早震旦世陡山沱组是华南地区重要的斜坡相分界标志。通过对该区构造与沉积、地层序列系统等进行研究,结合宏观与微观、点与面分析等手段,发现湘西北四都坪陡山沱组并不是深水相沉积。根据地层序列下部钙帽白云岩中的渗流构造和上部新发现的核形石,认为该区陡山沱组沉积序列、沉积特征与扬子地台北缘岩性组合基本一致,沉积环境为碳酸盐台地夹潮下凹地相沉积; 区分了碳酸盐台地台凹相与斜坡重力流,并对华南岩相古地理进行了新划分。
Abstract:
The Doushantuo Formation in Siduping, northwestern Hunan Province, has long been regarded as one important boundary marker of the slope facies zone in South China. However, in this study we found that the Doushantuo Formation in the Siduping area was not deep-water deposition, based on comprehensive analyses of tectonic and sedimentary features, stratigraphic sequence and lithology. The percolation structure in ‘cap dolomite’ of lower stratigraphic sequence and the oncolite newly discovered from the upper Formation suggests that the stratigraphic sequence and sedimentary feature in this area is basically consistent with that in the northern margin of the Yangtze Platform, being suggestive of carbonate platform intercalated with subtidal depression setting. Additionally, this study discusses the differences between the carbonate platform front facies and gravity-flow deposits in a slope setting, and redefines the lithofacies paleogeography of South China.
