地质作用过程持续时间的确定具有重要意义。前人已建立的地质定年方法 (同位素法、古生物法和古地磁法 )给出的是地质事件的“绝对年龄”或相对年代。但至今国内外尚缺乏有关地质作用持续时间的直接的测定方法。讨论了从构造地质学角度直接测定地质事件时限的一种新方法 The determination of the duration of geological processes is of great significance. The predecessors have established geological dating methods (isotope method, palaeontology and paleomagnetism method) gives the geological event “absolute age” or relative age. However, up to now, there are still no direct methods for determining the duration of geological processes. A new method to directly measure the time limit of geological events from the tectonic geology is discussed
