Pretoria / Johannesburg, South Africa, ... Diorite rock is an intrusive material intermediate of gabbro and granite rocks in terms of composition (Austin 1963). It finds location mainly in mountainous landscapes where it occurs in substantial amounts as batholiths. With rock composition of about 5-50% dark minerals

Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.

Diorite vs. gabbro comparison: Diorite is a coarse-grained rock mainly composed of plagioclase feldspar, biotite, hornblende, and sometimes pyroxene, while gabbro consists primarily of pyroxene, plagioclase feldspar, and olivine. Diorite is typically lighter in color compared to gabbro, which tends to be darker due to its higher iron content.

Notable places where norite is found in layered intrusions are Bushveld (South Africa), Stillwater (Montana, USA), and Skaergaard (Greenland) igneous complexes. Others are Sukinda and Nausahi (India), Gombak (Singapore), Great Dyke (Zimbabwe), and Rogaland igneous complex (Norway).

Diorite is most commonly found in continental crusts and is often associated with granitic intrusions. It is found in abundance in the Andes Mountains, the Himalayas, and the Canadian Shield. Diorite can also be found in smaller quantities in other areas around the world, including the United States, South Africa, and Australia.

Diorite rocks have emerged as a viable alternative to river sand. Botswana has an abundant occurrence of diorite rocks that are mainly located in mountainous landscapes as batholiths (McCoy, 2016). Diorite rock(s) are intrusive rocks in nature, they are classified under Igneous rock which can be plutonic (intrusive) and volcanic (extrusive).

The ca. 1100 Ma Namaqualand Metamorphic Complex is host to a number of vein-type monazite-apatite-chalcopyrite-magnetite deposits, which cluster in a approximately 30-km 2 area 160 km south of the Okiep copper district. The largest of these veins, at Steenkampskraal, has been mined intermittently since the late 1950s for thorium.
