摘要
辽东本溪地区新元古界青白口系非常发育,出露齐全。文章运用沉积学、地层学、层序地层学等理论,依据辽东本溪地区新元古界青白口系岩相岩石组合特征及空间展布规律的地质调查和研究成果,参考前人层序地层划分意见,将该区青白口系划分为2个三级层序;对层序内部的体系域进行研究,建立了本溪地区岩石地层格架和地层模型,认为该区青白口系在不同阶段的盆地演化过程继承了前期的古地理格局。
Neoproterozoic Qingbaikou System is widely developed and completely outcropped in eastern Liaoning province.The paper uses sedimentology,stratigraphy,sequence stratigraphy and other theory of geosciences to investigate characteristics of petrographic and rock association and spatial distribution pattern of the System then summarizes the previous researches and divide Qingbaikou System into two sequences III.The internal system tracts of the sequences are studied to establish model,stratigraphic framework of the system in Benxi area showing that evolution of Qingbaikou System at different stages inherited palaeogeographic pattern of the previous stage.
