Quartz diorite - Wikipedia

Quartz diorite is an igneous, plutonic rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine ) with 10% or less potassium feldspar.

diorite. Diorite is an intermediate intrusive igneous phanerites (large grain size) presenting hypidiomorphic (granular) to allotriomorphic (very large crystallographically continuous crystals) texture with about 60–80% of the Na–plagioclase, oligoclase and Na–Ca–plagioclase and little or no quartz.

Diorite - Wikipedia

The presence of significant quartz makes the rock type quartz-diorite (>5% quartz) or tonalite (>20% quartz), and if orthoclase (potassium feldspar) is present at greater than 10 percent, the rock type grades into monzodiorite or granodiorite.

Diorite's extrusive equivalent is andesite, meaning that andesite and diorite are made of the same minerals, but andesite rocks formed outside the earth instead. In other words, diorite is rock formed from cooled magma, and andesite is rock formed from cooled lava. Diorite is composed mainly of feldspar and small amounts of quartz and other ...

What is Diorite?

An igneous rock formed by subterranean crystallized magma, Diorite is composed of plagioclase feldspar, quartz, hornblende, pyroxene and biotite. Varieties that lack hornblende are referred to as "leucodiorite". The color of diorite varies from grey to dark grey to black, speckled with lighter colors that may appear white.
