摘要
根据地层层序保存程度,将造山带地层划分为史密斯地层、有限史密斯地层和非史密斯地层3种类型。有限史密斯地层是造山带地层的主要类型,它由不同时代、不同成因的构造地层断片组成,史密斯地层层序律仅适用于地层断片内部地层层序研究。文中认为有限史密斯地层的层序是可以恢复的,并提出了恢复方法和技术路线。最后,以活动论、单元论和阶段论为指导,论述了造山带地层系统研究的理论模型。
According to the level that the orogenic stratigraphy is damaged, it can be dividedinto three general types: Smith stratigraphy, limited-Smith stratigraphy and non-Smithstratigraphy. of them, limited-Smith stratigraphy is a main type in orogenic belt, and consistsof are stratigraphic slices formed in different geological times and in various tectonic settings.The faunal succession law of Smith can be used only in each of slices. The author thinks the se-quence of limited-Smith stratigraphy can be recovered, and the methods and paths of recoveringthe sequence of limited-Smith stratigraphy are discussed. Lastly, the ideal model of the regionalstratigraphy structure in orogenic belt is suggested under the guide of mobilism.
