河北省怀来中元古代铁岭组主要为一套滨浅海碳酸盐岩沉积组合。按微相组合或基本层序、沉积体系及沉积体系域逐级剖析的方法，可识别出６１个基本层序和潮坪、浅水陆棚及开阔陆棚等３种沉积体系。这３类沉积体系的周期性叠置组成了完整的海进—海退碳酸盐岩沉积序列，其顶底为明显的平行不整合。通过对该沉积层序的层序界面及最大海进面的追索，建立了怀来地区的地层格架，从而揭示了中元古代铁岭组沉积盆地的演化特征。
The Mesoproterozoic Tieling Formation in Huailai, Hebei Province is mainly composed of a set of shallow coastal carbonate sedimentary assemblages. Based on the micro-facies assemblage or basic sequence, sedimentary system and sedimentary system domain stepwise analysis, three basic sedimentary systems including 61 basic sequences, tidal flat, shallow water shelf and open shelf can be identified. The periodic stacking of these three types of sedimentary systems make up a complete sequence of marine-receding carbonate sedimentary sequences with obvious parallel unconformity. By tracing the sequence boundary and the maximum sea surface of the sedimentary sequence, the stratigraphic framework of Huailai area was established, which revealed the evolution characteristics of the sedimentary basins in the Middle Proterozoic Tieling Formation.
