Title
ANALYZING MESO-CENOZOIC TECTONIC-SEDIMENTARY CYCLES IN EAST CHINA ACCORDING TO TECTOSTRATIGRAPHY
摘要
根据构造地层学的原理和方法,将中国东部中、新生界划分为六个构造-沉积旋回,认为侏罗纪末幕运动是中、新生代最重要的、具有划分构造发展阶段意义的构造幕,从而把中、新生代构造演化史划分为三叠-侏罗纪、晚白垩世-第三纪两个阶段和早白垩世过渡阶段,并概述了每个阶段的基本构造特征。
Abstract
According to the basic comception of tectostratigraphy,the author divided the Meso-Cenozoic Systems in East China into six tectonic-sedimentary cycles and proposed that the Lower Eogene should belong to Upper Cretaceous,Upper Triassic to Lower Jurassic in South China and the Nanyang Basin to Cretaceous.An important tectonic generation in the end of Jurassic is significant in dividing the tectonic evolution history into two stages,that is,Triassic-Jurassic stage and Late Cretaceous-Tertiary stage.Two huge tectonic sys-tems that developed in the stages derived from the same origin but different from each other.Extensive tectonic uncomformities could be found between the tectonic systems,thus resulting in two dimensional feature of Meso-Cenozoic Systems in East China.
