Distinct Alteration Environments in Terra Sirenum, Mars

Abstract

Data returned from a variety of satellite missions to Mars have shown that the Terra Sirenum region of the southern highlands is unique area. Here, a diverse array of secondary minerals are found in close proximity, including chlorides, aluminum and iron/magnesium phyllosilicates, acidic sulphates (alunite and jarosite), as well as several calcium/magnesium sulphates. These minerals require the presence of water to form, so can help us understand the history of water in Terra Sirenum.
