地壳均衡地壳均衡isostasy描述地壳力学状态和升降运动的理论。它阐明地壳的各个地块趋向于静力平衡的原理，即在大地水准面之上，山脉的质量过剩由大地水准面之下的质量不足来补偿。1889年，美国地质学家C.E.达顿第一次提出地壳均衡这个词，并作了详细的讨论。20世纪初以后，形成了两种不同的地壳的均衡模型。①普拉特-海福德等压面模型。认为大地水准面以下某一深度处存在一个等压面。无论地形高低，等压面以上的质量处处相等。地形高处，其密度低；地形低处，其密度高。②艾里-海依斯卡宁等密度模型。认为地壳密度处处相等。地形高处的质量过剩由比地幔密度低的地壳山根来补偿，地形低的海水质量不足由地幔高密度的反山根来补偿。后有人对以上模型进行修正和发展，使之更符合于地球的实际。地幔对流和板块消减运动可能对地壳均衡有干扰，但就全球大范围而言，地壳仍趋于静力平衡状态。据统计，全球近90％的地区基本上处于地壳均衡状态。
