活动断层构造的研究方法与“老”构造的研究方法的一个重要差别,就在于它往往必须借助于各类地貌变形来确定断层活动的性质、方式、活动时代及活动速率;由于活动构造变形所涉及的第四纪地层在大陆地区的分布极其有限,所以各类变形构造地貌单元相当于老构造研究中地层学的基础。本文拟对作为“地层单元”的河流阶地、冰川地貌年代的确定进行探讨。 An important difference between the research method of active fault structure and the research method of “old” structure lies in that it often has to determine the nature, mode, activity time and activity rate of fault activity by means of various types of topographic deformation. Due to the tectonic deformation Quaternary strata involved in the distribution of the extremely limited in the mainland, so all kinds of deformed tectonic units equivalent to the study of stratigraphy in the study of the basis of the old structure. This article intends to discuss the determination of the terraces of the river and the era of glacier topography as the strata unit.
