How is granite formed - science.answers

Granite containing rock is widely distributed throughout the continental crust. Much of it was intruded during the Precambrian age; it is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Outcrops of granite tend to form tors and rounded massifs.

Granite - Yosemite National Park (U.S. National Park Service)

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 […]

Granite: Igneous Rock - Pictures, Definition & More

How Is Granite Formed? 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.

Igneous rocks are formed through crystallization from melt. All igneous rocks, with the exception of volcanic glass , are made up of interlocking crystals. In rocks that cool slowly, deep below the surface of the earth, these crystals can be quite large and visible to the naked eye.

In what way are large boulders formed? - Quora

Gneiss is formed from the high-temperature metamorphism of existing igneous rocks, generally granite or diorite. The rocks that form gneiss are exposed to extreme pressures and temperatures of between 600 and 700 degrees Celsius. These temperatures cause the individual minerals to migrate, forming distinct bands through the rock.
