Mafic rocks have between 45 and 55% of silica, whereas felsic rocks have over 65% of silica, the highest of all types. Due to the color of the minerals forming them, the rocks are either light or dark. As iron-rich silicates are normally dark in color, mafic rocks are dark-colored. Felsite is a very fine-grained volcanic rock that may or may not contain larger crystals. Felsite is a field term for a light-colored rock that typically requires petrographic examination or chemical analysis for more precise definition.
