Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new information on Mars' geological and climatic history. Phyllosilicates formed by aqueous alteration very early in the planet's history (the "phyllocian" era) are found in the oldest terrains; sulfates were formed in a second era (the "theiikian" era) in an acidic environment. Beginning about 3.5 billion years ago, the last era (the "siderikian") is dominated by the formation of anhydrous ferric oxides in a slow superficial weathering, without liquid water playing a major role across the planet.
欧洲航天局“火星快车”号航天器上搭载的“矿物、水、冰与活动观测台”（OMEGA）仪器对火星进行的全球矿物学绘图，为火星的地质和气候历史提供了新信息。在该行星历史早期（“叶序纪”时代）由水蚀作用形成的层状硅酸盐存在于最古老的地形中；硫酸盐形成于第二个时代（“硫ikian纪”时代）的酸性环境中。大约在35亿年前开始的最后一个时代（“铁ikian纪”），以无水氧化铁在缓慢的表面风化过程中的形成为主，整个星球上液态水未起主要作用。
