Facts about Granite

Granite

Polished granite stones are used in the team sport known as curling.

Granite

A granite containing both muscovite and biotite micas is called a binary or "two-mica" granite.

Granite

Most granite intrusions are emplaced at depths from 1.5 - 50 km (.9 - 30 miles) in the continental crust.

Granite

Small dikes of granitic composition called "aplites" are associated with granite margins.

Granite

Granite has been intruded into the Earth's crust during all geologic periods; much of it is of Precambrian age.

Granite

The production of granite by metamorphic heat is difficult, but it is observed to occur in certain amphibolite and granulite terrains.

Granite

The final mineralogy, texture, and chemical composition of a granite are often distinctive, based on its origin.

Granite

Granite comprises a number of minerals, primarily orthoclase and plagioclase feldspars, quartz, hornblende, and muscovite or biotite micas.

Granite

Many large Hindu temples in southern India, particularly those built by the eleventh-century king Rajaraja Chola I, were made of granite.

Granite

Today, granite continues to be used as a dimension stone (stone available in large quantities cut to specific sizes) in buildings and monuments.

Granite

Granite magma must make room for itself or be intruded into other rocks, and several mechanisms have been proposed to explain how large batholiths have been emplaced.

Granite

The word granite comes from the Latin granum, for grain, referring to the common, coarse-grained structure for this type of crystalline rock.

Granite

The granitization theory states that granite (or some types of granite) is formed in place by extreme metamorphism—that is, the solid-state recrystallization of pre-existing rock, under conditions of extreme heat and pressure.

Granite

How the Egyptians worked the solid granite is still a matter of debate.

Granite

The "alphabet-soup" classification is often used because it classifies granite based on origin of the "parental" magma from which the granite was formed.

Granite

The "avant-garde" was what Modernism was called at first, and the term remained to describe movements which identify themselves as attempting to overthrow some aspect of tradition or the status quo.

Granite

Two-mica granites are typically high in potassium and low in plagioclase.

Granite

Granite is currently known only on Earth, where it forms a major part of the continental crust.

Granite

Menkaure's Pyramid, likely dating to the same era, was constructed of limestone and granite blocks.

Granite

Granite is a hard, tough, igneous rock that is widely distributed in the Earth's continental crust.

Granite

contains a huge granite sarcophagus fashioned of red Aswan granite.

Granite

Both of these types of granite were formed by the melting of precursor rock called the protolith.

Granite

The amount of granite in them is said to be comparable to that used in the Great Pyramid of Giza.

Granite

The mother of the younger Crazy Horse was Rattling Blanket Woman (b.

Granite

The origin of granite is contentious and has led to varied schemes of classification.

Granite

The naming of various types of granite is based on their mineralogic composition, using what is called the "QAPF diagram" for coarse-grained plutonic rocks (granitoids).

Granite

Other uses of granite in ancient Egypt include columns, door lintels, sills, jambs, and wall and floor veneer.

Granite

Most geologists today accept that a combination of these processes may operate to produce granite intrusions, as no single mechanism provides an adequate explanation.

Granite

Later, "M-type" (mantle-derived) granite was proposed, to cover granites that clearly arose from magmas sourced from the mantle.

Granite

According to modern petrology, true granite contains both plagioclase and orthoclase feldspars.

Granite

When a granitoid is extremely rich in orthoclase, the rock is referred to as alkali granite.

Granite

An example of an A-type granite is a caldera at Yellowstone National Park.

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 surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.
