This versatile material is widely used in various industries due to its unique properties and abundant availability.
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. These rocks are rare on the surface, but make up peridotite, the rock of the upper mantle. It is poor in silica, in the 40% or less range.
