苏联地质学家不仅注意地壳在较古时代里所发生的运动及其变形,而且也十分重视发生在最新时代(自新第三纪起)及现代的构造运动。他们认为新的构造运动与老构造单位具有不可分割的联系,同时又有其本质的区別。因此他们的研究方法是辩证的。新大地构造的研究对科学与实践有重要意义,因 Soviet geologists not only pay attention to the earth crust in the ancient times occurred in the movement and its deformation, but also attaches great importance to occurred in the latest era (since the Neogene) and the modern tectonic movement. They think that the new tectonic movement is inextricably linked with the old tectonic units and at the same time has its essential difference. Therefore, their research methods are dialectical. The study of the new earth structure is of great importance to science and practice because
