摘要:
長期以來學者們一直認為湘西北四都坪早震旦世陡山沱組是華南地區重要的斜坡相分界標志。通過對該區構造與沉積、地層序列系統等進行研究,結合宏觀與微觀、點與面分析等手段,發現湘西北四都坪陡山沱組并不是深水相沉積。根據地層序列下部鈣帽白云巖中的滲流構造和上部新發現的核形石,認為該區陡山沱組沉積序列、沉積特征與揚子地臺北緣巖性組合基本一致,沉積環境為碳酸鹽臺地夾潮下凹地相沉積; 區分了碳酸鹽臺地臺凹相與斜坡重力流,并對華南巖相古地理進行了新劃分。
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.
