大陆拉伸构造区断裂构造的功能分类

THE FUNCTIONAL CLASSIFICATION OF FAULTS IN CONTINENTAL EXTENSIONAL TECTONIC AREAS

摘要: 在大陆拉伸构造区,各具功能的三组断层:伸展断层组、调整断层组、滑脱断层组,构成伸展链锁断层系,呈现出伸展构造的基本几何面貌。本文在指出各组断层的特征及鉴定标志后,论述了断层角色的空间转换,最后,建立了鲁西伸展链锁断层系。

Abstract: In continental extensional tectonic areas, there are three sets of faults with their respective functions, extensional faults, adjustment faults and detachment faults, which form an extensional chain fault system and Show the basic geometric pattern of extensional structure. This paper gives the features and identification criteria of the three sets of fault aud then deals with the spatial transition of their roles. Finally the Western Shandong extensional chain fault system is established.
