Granite Facts

Granite is an igneous rock with grains large enough to be seen with the naked eye. It is light-colored and forms from the slow crystallization of mama below the Earth's surface. It is made up mainly of quartz and feldspar. There are also minor amounts of mica, amphiboles, and other minerals. Due to its mineral composition, granite may appear as red, pink, gray, or white with dark mineral

Granite Article about granite by The Free Dictionary

Some granites are the oldest known rocks on earth; others were formed during younger geologic periods. Crystallized at depth, granite masses are exposed at the earth's surface by crustal movement or by the erosion of overlying rocks. Very coarse-grained granite, called pegmatite, may contain minerals and gemstones of economic value.

Mar 20, 2017 · Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that

Igneous Rocks. Igneous rocks (Granites). Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% SiO2, whereas granite is 73%. Intrusive, slowly cooled inside the crust. (Plutonic rock = formed in the earth).

Siliceous clastic rocks generally have greater heat production (2 to 4 HPU) than do chemical sedimentary rocks, including the carbonates (0.4 to 2 HPU). The heat production of metamorphic rocks generally depends on the radioelement contents of their igneous and sedimentary predecessors, modified by metamorphic processes.
