大陆漂移说大陆漂移说continentaldrift,theoryof解释地壳运动和海陆分布、演变的学说。大陆彼此之间和大陆相对于大洋盆地间的大规模水平运动称为大陆漂移。1912年德国人A.L.魏格纳提出,并在1915年发表的《海陆的起源》一书中作了论证。由于不能较好地解释漂移的驱动力机制问题,后受到地球物理学家以及持固定论的地质学家的反对而沉寂一时。50年代以后,随着古地磁学、地震学的发展以及地层学、古生物学、古地理学、区域构造学等对此研究所获大量资料的论证,大陆漂移说又获得进一步发展,并作为板块构造学发展的一个阶段性的里程碑而受到地学界的重视。大陆漂移说示意图大陆漂移说认为,地球上所有大陆在中生代以前曾经是统一的巨大陆块,称之为泛大陆或联合古陆。中生代开始,泛大陆分裂并漂移,逐渐达到现位置。泛大陆的存在及大陆破裂、漂移的证据主要有:①大西洋两岸的海岸线相互对应,特别是巴西东端的直角突出部分与非洲西岸呈直角凹进的几内亚湾非常吻合。②美洲和欧、非在地层、岩石、构造上的相似和呼应。③大西洋两岸古生物群具有亲缘关系。④石炭纪-二叠纪时在南美洲、非洲中部和南部、印度、澳大利亚等大陆上发生过广泛的冰川作用。⑤现代精确的大地测量数据证实大陆仍在持续缓慢地水平运动。⑥古地磁测量资料表明许多大陆现在所处位置并不代表其初始位置,而是经过了或长或短的运移。地图:大陆漂移说示意地图现代地球物理学研究对大陆漂移的动力机制的可能解释是与向西漂移的潮汐力和指向赤道的离极力这两种分力有关,较轻的硅铝质大陆块漂浮在较重的粘性硅镁层之上,由于潮汐力和离极力的联合作用而使泛大陆破裂并与硅镁层分离,并向西、向赤道作大规模水平漂移。但大陆漂移的机制问题尚不能认为已经解决。
