一、固定论与活动论之争自从“地槽”这一术语提出后,长期以来许多地质学者认为,在地球表面上产生的一个狭长的拗陷或断陷带,或产生于两个大陆之间的海沟,叫做地槽。在那里地面长期下降,沉积了巨厚的地层。后来经过地球动力作用,致使这个巨厚的地槽沉积带褶皱成山。地壳运动主要是垂直的升降运动。山脉的位置,即巨厚地层的分布地带,也就是地槽位置所在。它们在地球表面上的位置,始终没有大的变动。这就是所谓“固定论”。持地槽说者多相信这个概念。
THE PROBLEM OF FIXATION AND ACTIVITIES Since the term “geosyncline” has been put forward, many geologists have long believed that a narrow depression or fault zone on the surface of the earth is generated or originated from two Trench between the mainland, called the trough. Where long-term decline in the ground, deposited a thick layer. Later, after the earth’s dynamism, the gigantic trench-sinking belt folded into mountains. Crustal movement is mainly vertical movements. The location of the mountains, that is, the distribution of thick strata, that is, where the trough location. Their position on the surface of the earth, there is always no major changes. This is the so-called “fixed theory ”. Those who hold the ground believe more about this concept.
