Explain how the silica content of molten materials affects the color of igneous rocks?
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.
How are minerals arranged in igneous rocks?
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
