摘要
本文结合实例叙述了一种浅变质岩区地层层序建立和检验的方法.在浅变质岩区建立地层层序,首先应充分搜集各种原生和变形结构要素,鉴定岩层的变新方向、构造面向、构造降向,进行构造组合和应变分析,确定构造样式群特征.其次,依构造样式群特征,建立地层层序,划分地层.最后本文通过对湖北大洪山花山群区测填图、沉积环境与地层成因分析检验了所建立的地层层序.
It is difficult to establish the stratigraphic sequences in the area of low grade rock. This paper introduces a method for a solution. Firstly, we should judge stratigraphic younging up, structural facing, vergence and determine tectonic style. Secondly stratigraphic sequence can be established on specific feature of the tectonic style. This has been used and correlated by author in analysising sedimentary system and mapping upper Proterozoic Huashan Group in Dahong-shan Mountain, Hubei provence.
