在目前的分析精度水平下，玄武岩分异过程中的镁同位素分馏通常被认为是可以忽略不计的。然而，在某些高度演化的火山岩中可以观察到镁同位素变化，其镁含量为0.4ppm（δ Mg-26）。
Magnesium isotopic fractionation during basalt differentiation is commonly thought to be negligible at current levels of analytical precision. However, Mg isotopic variation of similar to 0.4 parts per thousand (delta Mg-26) can be observed in some highly evolved volcanic rocks with MgO contents of
