The most voluminous volcanism on earth occurs at ocean ridges and island arcs. Spectacular differences in eruptive behaviour and development of important ore deposits are related to major differences in the degree of magma oxidation involved. The project will discover whether these differences are source controlled or develop during ascent.

地球上最大的火山活动发生在洋脊和岛弧上。重要矿床在喷发行为和开发方面的巨大差异与所涉及的岩浆氧化程度的重大差异有关。该项目将发现这些差异是受源头控制的，还是在提升过程中发展起来的。
