在华北(东经104°～122°,北纬34°～41°)136万平方公里面积内,使用123张1:100万陆地卫星(LANDSAT～1、2、3)的黑白多光谱扫描照片镶嵌,解译出了各类线性破裂4737条1),发现它们同地壳厚度之间存在某种比例关系,并与某些岩石破裂实验结果相对应;在大范围量测和统计两组破裂的夹角时,又发现其锐角指向可能反映大区应力场的主压应力轴向,同其他方法得到的结果符合较好。本文是卫片地质解译同地壳构造和大区应力场关系的一次探讨。
In the area of 1.36 million km 2 in North China (104 ° ~ 122 ° longitude and 34 ° ~ 41 ° North latitude), black and white multi-spectral scanning photographs of 123 1: 1 million land satellites (LANDSAT ~ 1,2,3) Interpretation of the various types of linearly fractured 4737 1), found that there is a certain relationship between the crustal thickness and some of the rock fracture test results corresponding to; in a wide range of measurements and statistics of the angle between the two sets of ruptures , It is also found that the acute angle is in the direction of the principal compressive stress which may reflect the stress field in large area, which is in good agreement with the results obtained by other methods. This article is a discussion of the relationship between the interpretation of geology and the crustal structure and the stress field in a large area.
