地幔柱地幔柱mantleplume深部地幔热对流运动中的一股上升的圆柱状固态物质的热塑性流,即从软流圈或下地幔涌起并穿透岩石圈而成的热地幔物质柱状体。它在地表或洋底出露时就表现为热点。热点上的地热流值大大高于周围广大地区,甚至会形成孤立的火山。地幔柱概念是由J.摩根于1972年提出的,其所根据的事实是:洋底有一系列海山,即呈链状分布的死火山脉,它一端连接着现代活火山,沿此链距离活火山越远,其年龄越老。这被认为是当岩石圈板块运动时,固定不动的地幔柱在板块表面留下的热点迁移的轨迹,也可以说是由一系列死火山组成的无震海岭。如夏威夷活火山热点,因太平洋板块西移而在洋底留下一条由死火山形成的海山链,经年龄值4000万年的中途岛转折而成向北西延伸的皇帝海岭,一直到阿留申岛西端,年龄增至7500万年。地幔柱估计至少来自700千米或更深处,直径大致在100~250千米左右,上升速率约每年几厘米,由此导致地幔顶部成直径达上百千米的穹状隆起,高出四周约1~2千米。全球热点大多位于洋中脊的转折拐点或三联点上,少数在板块内部,总共约30余个。陆上较少,约5个。
