断层生长指数不仅与断层活动速率有关,而且还与沉积速率有关,而后者长期以来为人们所忽视.确定沉积速率得先求出沉积时间,然而已知沉积时间可直接得到断层活动速率并定量地反应断层活动强度.因此,“断层生长指教”一词已无实用价值.

The growth index of a fault is related not only to its speed of activity but also to the deposition rate which has been neglected foralong time. The duration of sedimentation has to be established in order to evaluate the sedi-mentary rate. Hower, the speed of activity ofafault can be directly abtained from the duration of sedimentation and reflects quantitatively the activity intensity of the fault, thus the terminology of the growth index of fault is practically meaningless.
