Diorite results from the partial melting of a mafic rock above a subduction zone. It is found in volcanic arcs, and in cordilleran mountain building, such as in the Andes Mountains.

Diorite is the name used for a group of coarse-grained igneous rocks with a composition between that of granite and basalt. It usually occurs as large intrusions, dikes, and sills within continental crust.

Diorite is an intrusive, coarse-grained, igneous rock, meaning it forms from the slow cooling and solidification of magma (molten rock) underground. Diorite is typically composed of plagioclase …

Diorite, medium- to coarse-grained intrusive igneous rock that commonly is composed of about two-thirds plagioclase feldspar and one-third dark-coloured minerals, such as hornblende or biotite.

May 15, 2018 · Definition of Diorite: Diorite is a coarse-grained igneous rock that falls within the plutonic category, meaning it forms deep beneath the Earth’s surface through the cooling and solidification of …

Diorite is an intrusive igneous rock composed primarily of plagioclase feldspar and smaller amounts of mafic minerals like hornblende and biotite. It has a phaneritic texture, meaning its interlocking …

Diorite is a coarse-grained intrusive igneous rock with intermediate composition. It is the intrusive equivalent of andesite and forms from the slow cooling of intermediate-composition magma deep …

Oct 5, 2015 · Diorite is a plutonic igneous rock with intermediate composition between mafic and felsic rocks. It is visibly crystalline and usually has a granular texture (composed of roughly equally sized …

Diorite is an intrusive rock intermediate in composition between gabbro and granite. It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots …

Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar, biotite, hornblende, and/or pyroxene. The chemical composition of diorite is intermediate,...
