| 摘 要： | 进行世界占大陆再造需要3个步骤:（1）确定各古大陆块体的边界;（2）进行必要的陆块拼合处理;（3）恢复各个占大陆块体正当时的方位和位置。第一步是地质学上的判断问题,第二步和第三步是应用微型计算机进行处理,涉及大陆地块在地球表面运动时球面几何学中的欧拉极和欧拉旋转问题。本文介绍在IBM-PC/AT微型电子汁算机上进行占大陆再造的方法,同时讨论了古生代古大陆再造的特殊性。最后给出了震旦纪、泥盆纪5张不同投影实例图作为说明。

| Abstract: | A series of world reconstuction maps of Palaeozoic continents have been made by the use of an IBM/PC-AT microcomputer. There are three different steps in the task. They are: (1) geologic delimitation of the boundaries of each palae-ocontinent, (2)necessary fitting, and (3)relocation of the palaeocontinents. The first step depends merely on the geologic judgement and the last two steps involve a new composite application of the problem of Euler's poles and Euler's rotations in plate tectonics geometry. The authors have developed a FORTRAN programs to handle the problem. With the help of Auto-CAD the programme automatically produces reconstruction maps of several different kinds of projections. In this paper, methods of making the reconstruction maps are described and the speciality of reconstructions in the Palaeozoic are diseussed. At the end, world reconstruction maps of diferent projections in the Devonian and in the Sinian Periods are given as examples. |
