在 500–600°C、800–1000 bar 下与海水进行实验反应的海洋拉斑玄武岩具有与未改变的玄武岩基本相同的稀土元素 (REE) 丰度和分布模式。尽管数据表明存在一些稀土元素浸出和再分布的可能性，但净效应很小，受海底热液过程影响的玄武岩的稀土元素模式仍然可能是有效的成岩指标。
Oceanic tholeiites that have been experimentally reacted with seawater at 500–600° C, 800–1000 bars, have rare earth element (REE) abundances and distribution patterns that are essentially identical to those of the unaltered basalts. Although the data indicate the possibility of some REE leaching and redistribution, the net effects are small and the REE patterns of basalts affected by submarine hydrothermal processes may still be valid petrogenetic indicators.
