A grey intrusive igneous rock composed mostly of plagioclase feldspar, biotite, hornblende and/or pyroxene
A coarse grained igneous rock of intrusive origin that is darker and chemically more mafic than granite
Medium-to coarse-grained igneous rock that commonly is composed of about two-thirds plagioclase feldspar and one-third dark-coloured minerals, such as hornblende or biotite. Diorite has about the same structural properties as granite but, perhaps because of its darker colour and more limited supply, is rarely used as an ornamental building material. It is one of the dark gray stones that is sold commercially as "black granite
Any of a group of dark, phaneritic, intrusive rocks that are the plutonic equivalents of andesite
Igneous plutonic rock, less mafic than gabbro, but more mafic than granite and granodiorite; rough plutonic equivalent of andesite
A granular crystal line igneous rock commonly composed of plagioclase and hornblende, pyroxene, or biolite
A coarse-grained igneous rock of intermediate chemical composition
A phaneritic intrusive igneous rock consisting mostly of intermediate plagioclase feldspar and pyroxene, with some amphibole and biotite
an intrusive rock of magnatic origin
A groupe of plutonic rocks intermediate in composition between acidic and basic, characteristically composed of hornblende, oligoclase, or andesine, pyroxene, and sometimes a little quartz
a granular crystalline intrusive rock
Rather hard and solid stone, mined in the Aswan region, used for buildings and statues One of the best king portrait, "Cephren with Horus" is sculptured to diorite
An igneous, crystalline in structure, consisting essentially of a triclinic feldspar and hornblende
It includes part of what was called greenstone
{i} variety of dark-colored igneous rock composed of feldspar and ferromagnesium silicates (Geology)
diorite-plagiogranitic
Composed of diorite and plagiogranite
quartz-diorite
any form of diorite containing appreciable amounts of quartz
quartz diorite
(Jeoloji) Quartz diorite is an igneous, plutonic (intrusive) rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less potassium feldspar. Quartz is present at between 5 to 20% of the rock. Biotite, amphiboles and pyroxenes are common dark accessory minerals
