最近十年来,在地质文献中对现代大洋中构造运动的形式和规模展开了热烈的讨论。自从新全球构造学说出现之后,对现代大洋底各种不同性质的构造运动中的水平运动给予了极大的注意。应当指出,根据这个学说,最主要的水平运动发生在软流圈中,而在两个洋底表面却表现为大洋中脊轴部的扩张带、转换断层以及沿着它们的扭动位移。1969年,裴伟(А.Б.Пейве)曾在其著名的对比大陆蛇绿岩套及大洋壳的论文中指出,在大洋中还应广泛发育着像混杂岩(Меланж)及滑乱层(Олистострома)这样一些构
In the last decade, there has been heated discussion in geological literature about the form and scale of the tectonic movement in the modern ocean. Since the advent of the new global tectonic theory, great attention has been paid to the horizontal movement in the tectonic movements of different nature at the modern ocean floor. It should be noted that according to this doctrine, the most important horizontal movement occurs in the asthenosphere, whereas on the two ocean floor surfaces it is characterized by the expansion of the axial mid-oceanic ridges, the transformation faults and the torsional displacements along them. In 1969, Pei Wei (А.Б.Пейве) pointed out in his famous paper on the ophiolites and oceanic crusts of the continent that there should be extensive development in the oceans such as Меланж and ostracism Олистострома) Such a structure
