西伯利亚面积达800多平方公里,其地质构造多样,范围包括三个巨大构造:西西伯利亚(年轻的)台坪、东西伯利亚(古老的)台坪和阿尔泰—萨彦褶皱区。同时分析沿地震测深稀疏剖面网的地质—地球物理资料表明,地壳深部结构同地壳上层构造格架存在着密切的关系。这就可以利用深部结构的信息来认识地壳各段的发育史,弄清现代构造作用的机制以及预测不同类型矿产在地壳剖面上部的分布。前些阶段的研究有小比例尺区域航空磁测和重力测量,是西伯利亚深部结构的主要信息来源。这些研究结果旨在解释地壳深部结构。但是实践表明,研究深部结构的方法只根据势场解释,若不使用地震勘探作为标准资料(其中包括地震测深资料),其效果是不大的。
Siberia, covering an area of more than 800 square kilometers, has a wide range of geological formations and consists of three immense structures: West Siberia (young) Ping, East Siberia (ancient) Ping and Altai-Sayan folds. Simultaneous analysis of the geophysical and geophysical data along the seismic profiling sparse section network shows that there is a close relationship between the deep crustal structure and the upper crustal tectonic framework. This allows the use of deep structure information to understand the developmental history of crustal segments, to understand the mechanisms of modern tectonism, and to predict the distribution of different types of minerals in the upper portion of crustal profiles. Studies in the earlier stages included a small-scale aeromagnetic survey and gravimetry and were the main sources of information on the deep structure of Siberia. These findings are intended to explain the deep crustal structure. However, practice shows that the method of studying the deep structure is only explained by the potential field. The effect of using seismic exploration as standard data (including seismic sounding data) is not significant.
