大地构造学是一门研讨地球(主要是地球上部)构造运动、地质构造形成机制和动力来源的科学。它不但对于探索天体(特别是地球)的起源、演化,解释地质体的时-空分布规律和地震成因、分布,具有深远的理论意义,而且对于矿产预测、地震预报也具有重要的实际意义。由于大地构造学涉及的内容广泛,有很多未知数,因此它又是一门探索性很强,而又十分活跃的地质学科。古今中外,争论甚多。新的假说
Geotectonics is a science to study the tectonic movement of the Earth (mainly the upper part of the Earth), the formation mechanism of geological formations and the source of power. It not only has a far-reaching theoretical significance for exploring the origin and evolution of celestial bodies (especially the earth), explaining the time-space distribution laws of geologic bodies and the genesis and distribution of earthquakes, but also has important practical significance for mineral prediction and earthquake prediction. Because of the wide range of the tectonics involved, there are many unknown, so it is a very exploratory, but very active geology. Ancient and modern, many controversies. New hypothesis
