镁是硅酸盐和碳酸盐矿物、水圈和生物圈的主要成分。镁在这些储层之间不断循环。由于镁的每个主要行星储层具有不同的镁同位素比率，因此可以使用镁同位素比率来追踪1）从整个行星到微观的空间尺度上镁循环的过程，以及2）这些储层之间的相对通量。本文总结了一些关键的动机，成功和面临的挑战，使用镁同位素来构建海水镁预算，现在和过去。
Magnesium is a major constituent in silicate and carbonate minerals, the hydrosphere and the biosphere. Magnesium is constantly cycled between these reservoirs. Since each of the major planetary reservoirs of magnesium have different magnesium isotope ratios, there is scope to use magnesium isotope ratios to trace 1) the processes that cycle Magnesium at a spatial scales from the entire planet to microscopic and 2) the relative fluxes between these reservoirs. This review summarises some of the key motivations, successes and challenges facing the use of magnesium isotopes to construct a budget of seawater magnesium, present and past.
