4.1: Classification of Igneous Rocks
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.

6 Igneous Rocks and Silicate Minerals – Mineralogy
Magmas richest in SiO 2, such as alkali granite, granite, and tonalite are generally deficient in MgO.We term such magmas silicic (Si-rich), or felsic (contraction of feldspar and silica).Light-colored minerals dominate felsic rocks, so many geologists use the term felsic to refer to any light-colored igneous rock, even if the chemical composition is unknown.
