Quartz diorite

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 and 20% of the rock. Biotite, amphiboles and pyroxenes are common dark accessory minerals.

Diorite: Igneous Rock Pictures, Definition & More

Diorite is usually composed of sodium-rich plagioclase with lesser amounts of hornblende, biotite, and pyroxene minerals. It usually contains little if any quartz. This makes diorite a coarse-grained rock with a contrasting mix of black and white mineral grains. Students often use this "salt and pepper" appearance as a clue to the identification of diorite.

Diorite Rock Composition, Formation and Uses Area

Diorite Composition. Diorite composition principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene. The chemical composition of diorite is intermediate, between that of maficgabbro and felsic granite. It may contain small amounts of quartz, microcline ,and olivine.

USGS: Geological Survey Bulletin 1359: Geology and Mineral

28/03/2006 Granodiorite and quartz diorite both contain 10-25 percent quartz. Some rocks contain principally biotite, others principally hornblende, and some contain equal amount of both minerals. In some areas the primary dark minerals have been largely altered to chlorite. Accessory minerals of both rock types are commonly magnetite, zircon, apatite, and sphene.

In thin section this diorite contains laths of plagioclase feldspar often 2-3 millimetres long, and minor amounts of quartz. The mafic minerals are dominated by high relief pyroxene with it's characteristic cleavage, and common biotite which exhibits some pleochroic haloes caused by zircon inclusions.

Geology: The Density Of Quartz Diorite

16/10/2012 Quartz diorite is an intrusive igneous rock, meaning it was originally molten material that solidified underground. This rock is a mixture of the minerals feldspar, pyroxene, hornblende and quartz, which exist in varying proportions. The amount of quartz in a quartz diorite rock, for example, can vary from 5 percent to 20 percent.

What Is Diorite? And Where Is Diorite Found

26/08/2020 The presence of significant quartz in diorite makes rock type quartz-diorite. A diuretic rock containing no quartz and feldspathoid minerals is called foid diorite according to its content. It is found in phenytoin and often includes the size of coarse grains and the composition of sprouted grains and sometimes porphyritic.

Andesite is diorite's extrusive equivalent: They are made of the same minerals, but andesite rocks are formed from aboveground lava flows instead of underground magma pockets. Granite is like diorite, but with more quartz in it. That's why crafting diorite blocks with Nether quartz yields granite blocks.

01/12/2017 Diorite might contain small amounts of apatite, ilmenite, microcline, and other minerals. It is rated as 7 on the Moh’s hardness scale (about the same as quartz), and possesses a speckled, or "phaneritic", appearance due to the presence of a mixture of minerals in its composition. It has a coarse, grainy structure, wherein its large grains are arranged in an interlinked pattern. The density

Diorite is composed primarily of plagioclase feldspar, amphibole, and pyroxine minerals with small amounts of biotite mica. It typically contains very little quartz. Zircon, apatite, sphene, magnetite, ilmenite and sulfides occur as accessory minerals. Varieties deficient in hornblende and other dark minerals are called leucodiorite.
