Black Galaxy Granite

Granite rocks are igneous rocks, which were formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Granite is used for long lasting monuments and  (http://maplered.com)  for trim and  (http://maplered.com)  decoration on buildings. Igneous rocks are called fire rocks and  (http://maplered.com)  are formed either underground or aboveground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets.
