    Notes: [Auszug] The red colour of the surface of Mars has long been attributed to Fe3+-bearing minerals in the regolith, implying that oxidizing conditions have prevailed. However, the apparent enrichment of iron in martian regolith, its mineralogy and the nature of the unweathered parent rocks remain poorly ...

    Notes: [Auszug] One type of manganese mineralisation is related to calc-alkaline magmatism. Reports on porphyry copper deposits and numerous manganese ore deposits have revealed that the two mineralisations seem to be contemporaneous within calc-alkaline terrains11. Porphyry copper deposits consistently occur over ...
