华北克拉通南缘中条山地区汝阳群沉积特征与层序地层分析
Sedimentary characteristics and sequence stratigraphic of Ruyang group in Zhongtiaoshan area in south margin of north China Craton
摘要
Abstract
To establish the sequence stratigraphic framework of the Ruyang group in the Zhongtiaoshan area in Yongji, Shanxi province, clarify sedimentary and evolutionary characteristics and form a reasonable sedimentary model, research was performed on the sedimentary environment and sequence characteristics of Ruyang group in the study area using sedimentology theory based on the observation and measurement of field outcrops, thin section data and the identification of outcrop sequence boundary.The characteristics, relationship and responses to eustatic sea-level change of each sequence have been stated systematically, and the sequence stratigraphic framework and sedimentary model are established.The result shows that the sedimentary system belongs to the tidal plat in barrier island and mixing deposits of clastic-carbonate.There are three types of sedimentary facies:barrier-type coastal facies, mixed coastal facies and shallow shelf facies, and three subfacies and six microfacies are identified.The Ruyang group was divided into six third-order sequences whose depositional systems tract is composed of transgressive systems tract and highstand systems tract and the distribution of sedimentary systems in Baicaoping formation and Beidajian formation are controlled by provenance and relative sea level changes.Finally, two facies models of barrier type coastal sedimentation and mixed sedimentation are established.关键词
