WebJul 15, 2024 · Eruptions built up enormous mountains of iron-rich igneous rocks that give the Martian crust its characteristic red hue. One of the most volcanic crusts in the solar system is that of Jupiter’s moon Io. The rich sulfide rocks in the Ionian crust paint the moon a dappled collection of yellows, greens, reds, blacks, and whites. WebIt is mostly made of dark minerals like pyroxene and olivine, which are rich in iron and magnesium and relatively poor in silica. Mafic rocks are low in silica, in the 45-50% range. Ultramafic refers to the extremely mafic rocks composed of mostly olivine and some pyroxene which have even more magnesium and iron and even less silica.
