地台是地壳的兩大基本搆造單元——即地槽区和地台区——之一。和地槽区相反,它是一个業已“穩定了”的地区。过去在人們的观念中,所有地台区域那是“穩定”的,但据苏联学者的研究結果,实际上有些地台建成以后,經过或長或短的“穩定”时期以后,曾出現过强烈的、顯非一般地台所常有的活动。这种有过重新活动的地台,叫做“活化地台”。如同我們所知,活化地台在中國境內分布特广(参考)。所以正确地辨識这种構造区域对于我們 The platform is one of the two basic structural units of the crust - the terrain and platform areas. In contrast to the trough area, it is an area that has “stabilized”. In the past, people used to think that all platform areas are “stable,” but according to the results of Soviet scholars’ studies, in fact, some stations have been built after the long or short “stable” period Strong, obviously non-ordinary activities often station. This has been re-activated platform, called “activated platform.” As we know, Activated Platform is widely distributed in China (Reference). So correctly identify this area of ​​construction for us
