What is the difference between light and dark silicate minerals?

What is the difference between light and dark silicate minerals? Earth's crust. The most abundant mineral group found in the Earth's crust is the silicate group.

Contact metamorphism is a type of metamorphism where rock minerals and texture are changed, mainly by heat, due to contact with magma into cooler surrounding rocks. Regional metamorphism is a type of metamorphism where large-scale tectonic movements of Earth's lithosphere plates that alter the pressure temperature conditions of the rocks.
