Granite Granites are coarse-grained rocks with a mottled appearance They comprise a mixture of glassy quartz, white, pink or red alkali feldspar, minor amounts of dark minerals, and often white, sodic plagioclaseTheir low density and resistance to weathering means that they usually form high, rugged terrains

Granite is an igneous rock that forms when a pocket of magma rises into the upper levels of the Earth's crust and slowly cools Cooling slowly gives granite, which is composed mainly of feldspar and quartz, enough time to develop large crystals that make the stone very hard and strong Some granite .
Igneous Rocks Igneous rocks are formed from lava or magma Magma is molten rock that is underground and lava is molten rock that erupts out on the surface The two main types of igneous rocks are plutonic rocks and volcanic rocks Plutonic rocks are formed when magma cools and solidifies underground Volcanic rocks are formed from lava ,
Classification of igneous rocks is one of the most confusing aspects of geology This is partly due to historical reasons, partly due to the nature of magmas, and partly due to the various criteria that could potentially be used to classify rocks Early in the days of geology there were few rocks .

Granite forms when bits of quartz and feldspar shoot out of volcanoes, so it’s one kind of igneous rock The word “granite” comes from the Latin word “granum”, a grain, because granite is made of lots of smaller bits of quartz and feldspar stuck together (think of our word “granary”, a place where you store [,]
Jun 05, 2016· Granite is an intrusive igneous rock with large grains (minerals) easily seen by the naked eye Granite colors are most commonly pink, white, variations of grey and black However, it's important to note that some stones marketed as black 'granite' are in fact likely gabbro as granite must contain at least 20% quartz within a rock to ,
GRANITE Granite is a coarse or medium-grained intrusive igneous rock that is rich in quartz and feldspar (k-feldspar and plagioclase); it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth

The key element for igneous rocks is magma; magma is a mixture of molten or semi-molten rock, as well as some gases and other volatile elements The deeper you go underground, the hotter it gets, and if you go deep enough, you reach the mantle – which can be thought of as a huge layer of magma .
