裂谷裂谷riftvalley地球深成作用的地表坳陷构造,以高角度断层为界呈长条状的地壳下降区,是数百至上千千米长的大型地质构造单元。英国人C.W.格雷格里1894年首先提出。裂谷是板块构造运动过程中,大陆崩裂至大洋开启的初始阶段的构造类型,也是岩石圈板块生长边界的构造类型,在陆壳区大洋中脊上均有发育。现今规模最大的裂谷发育在各大洋盆的洋中脊上,裂谷形态保持良好,特征明显。一般谷宽25~30千米,高出最深洋底2~3千米,与附近洋底高差为0.5~1.5千米。全球洋中脊裂谷总长在6万余千米。洋中脊裂谷带虽经常被转换断层截断错开,但仍明显地连贯分布。大陆裂谷按形成方式的不同,可分为主动裂谷和被动裂谷两类。主动裂谷是地幔的上升热对流的长期作用,使大陆岩石圈减薄、上隆而致破裂,然后出现坳陷而成裂谷,如东非裂谷、红海亚丁湾。被动裂谷则是由于地壳的伸展作用或剪切作用,使岩石圈减薄、破裂而导致裂谷的形成。
