Composite stratigraphic division of the Mesoproterozoic Shuangqiaoshan Group in northern Jiangxi

  • 摘要: 赣北前震旦系浅变质岩系一直是华南前震旦系地质研究的一个前缘阵地。多年来,在构造古地理研究方面有巨大进展,而在地层划分与对比上则相对不足。双桥山群是一大套变形强烈、岩性单调、缺乏标志层的特殊岩类。对这套特殊岩类需抓住内部的原始的沉积构造组合特征的差异,才能进行有效划分与对比。采用综合地层学方法,可以丰富岩石地层单位的研究内容,为划分提供更多的天然标志。
    Abstract: The Mesoproterozoic Shuangqiaoshan Group as the widespread pre-Sinian low-grade metamorphic rock series in northern Jiangxi has long been the frontier field in the studies of the geology of the pre-Sinian strata. The Group is characterized by simple lithology, severe deformation of the rocks, and absence of marker beds. The authors contend that it is imperative to subdivide the internal primany sedimentary structures so that the stratigraphic division and correlation can be effectively made.
