本文所称的相当层的错动,即构造地质学教科书中所称的视错动(apparent movement,据M.P.毕令斯)。本文所提出的问题,在构造地质学教科书中是有论述的。M.P.毕令斯写道:“被错动岩层的视错动,可以与总错距有很大的不同。这一点是非常重要的,但不能过于强调。视错动是许多变数的函数,它不仅决定于总错距,而且还决定于断层的走向和倾斜,被错断岩层的走向和倾斜,以及进行观察的表面的产状”。而本文作者对此问题有较长时间的思考,体会较深,同时在实际的地质工作中,对此问题往往注意得不够,所以作为问题讨论予以刊出。
The equivalent layer of displacement, referred to in the textbook of structural geology as referred to in this article, is apparent movement (according to M. P. Biol.). The issues raised in this paper are discussed in the textbook of structural geology. MP Biridges writes: “It is important, but not overly emphasized, that the error of the dislocated rock can be quite different from the total error of the rock. The dislocation is a function of many variables Not only on the total fault distance, but also on the strike and tilt of the fault, the strike and tilt of the fault rock, and the appearance of the surface being observed. ” However, the author of this paper has a long time to think about this issue and has a deeper understanding. At the same time, in actual geological work, this problem is often noticed enough, so it should be published as a discussion of problems.
