Granite - Wikipedia

Granite (/ ˈ ɡ r æ n ɪ t /) is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a completely crystalline rock. Strictly speaking, granite is an ...

Granite-Related Ore Deposits | One Hundredth …

Three major categories of ore deposits—granite-related sensu stricto—were selected for detailed analysis: disseminated magmatic mineralization in granites themselves (rare metal granites); hydrothermal deposits, imprinted on the granites and their immediate vicinity (vein and greisen type); and late-magmatic pegmatites largely spread around parental granitic plutons (rare element pegmatites).

Granite - Rausser College of Natural Resources

Granite is used as a building and ornamental stone. Many ore deposits (copper, lead, zinc, gold, and silver, for example) were produced by hydrothermal solutions created during late stages of cooling of granite bodies. These may be emplaced around the peripheries or related to fissures and fractures within bodies of granite. approx. 27% quartz + mica, amphibole, pyroxene, albite feldspar, a ...

The Beauvoir granite (Massif Central, France) represents an exceptional case in the European Variscan belt of a peraluminous rare-metal granite crosscutting an early W stockwork. The latter was strongly overprinted by rare-metal magmatic-hydrothermal fluids derived from the Beauvoir granite, resulting in a massive topazification of the quartz-ferberite vein system.
