摘要
笔者认为红安群属层状有序变质岩系。在野外调查研和对前人测制的剖面资料综合研究基础上，重新提出了红安群南、北岩相区的地层序列划分方案，利用原岩组合及标志层组合确立了红安群南，北区地层序列对比关系以及区域对比方案。该文澄清了红安群地层划分中若干有争议的问题，对鄂北相关岩系的统一划分、探讨该区中－晚元古代沉积盆地及其构造演化具有重要意义。
It is considered that Hongan Group is a stratified ordering metamophic rock series. Based on field investigation and study of the former profiling data, the subdivision plan of the stratigraphic sequence for the south and the north lithofacies region of Hongan Group has been advanced anew. Additionally, the stratigraphic sequence correlation between the south and the north lithofacies region or even the regional correlation of Hongan Group have been established by means of the protolith association and the marker beds association. This paper has clarified some controversial issues which has importent significance for unifying the division of the correlated rock series and approaching the sedimentary basin of Meso - Paleoproterozoic Era and its tectonic evolution in northern Hubei province.
