摘要
本文根据在地层记录中识别的基本层序、基本层序组和层序界面,将该陆相盆地充填序列分为4个层序,并根据岩石地层单元和沉积体系在时空上的展布特征建立盆地岩石地层格架;进而从古气候、湖平面升降、物源供给和构造作用等4个方面对层序地层成因机制进行初步分析,结果表明控制陆相盆地层序界面和层序结构的主要因素是构造运动和古气候。
The strata of this terrigenous red basin in Sichuan are divided into four sequences and nine basic sequence sets (or subsequence), and the lithostratigraphic framework is also set up here. It is considered that the formation of sequence stratigraphy of this terrigenous red basin was resulted from climatic,change of lake level,source of sediments and tectonism. It is also concluded that tectonism and climatic condition control the development of sequence boundary and sequence texture.
