The black grains can be biotite or hornblende. Numerous other minerals can be present in granite. ADVERTISEMENT What is Granite? Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's ...
Is granite a metamorphic or igneous? Granite is anigneous rockthat forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called g...
