Concordia, Northern Cape - Wikipedia

Concordia is a town in Namakwa District Municipality in the Northern Cape province of South Africa.The distance from Concordia to Cape Town is approximately 600 km (370 mi). Concordia was originally established as a Rhenish mission station in 1852 and copper mining began in 1853 through to 1983 in the area. The town is of historical interest because it is situated at the origin of mining,Orbicular granite - Wikipedia,South Africa. In the Namaqualand, South Africa, just west of the small town of Concordia, there is a rare occurrence of orbicular granite. The outcrop, known as Orbicule Hill or "wonderkoppie" (as it is locally known), is a provincial heritage site and one of just two known occurrences inRare earth element geochemistry of an anorthosite-diorite,,Earth and Planetary Science Letters, 87 (1988) 409-422 409 Elsevier Science Publishers B.V., Amsterdam - Printed in The Netherlands [1] Rare earth element geochemistry of an anorthosite-diorite suite, Namaqua mobile belt, South Africa J.A.

Diorite vs Kimberlite - Compare Nature

Diorite vs Kimberlite Characteristics. Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Diorite vs Kimberlite characteristics assist us to distinguish and recognize rocks.Diorite: Igneous Rock - Pictures, Definition & More,Diorite is an intrusive igneous rock of intermediate composition. Uses of Diorite. In areas where diorite occurs near the surface, it is sometimes mined for use as a crushed stone.It has a durability that compares favorably to granite and trap rock.It is used as a base material in the construction of roads, buildings, and parking areas.Orbicular Diorite - Microscope,However, orbicular diorite is an extremely rare variety of the rock that contains many spherical lumps, or orbs, that exhibit concentric zones of light and dark color. Once only known on the island of Corsica, occurrences of orbicular diorite have now been found in South Africa, North Carolina, and a

Far to the south, Win Swe (1975) described dacite porphyry dykes and possible sills from the Mergui Group near Mergui town and from islands to the north. Other than diorite, dykes similar to those in the Slate belt intrude the Kyaukhsu Taung Formation in the Paung Laung-Mawchi zone (Chapter 5) and so are post-Jurassic.(PDF) The Bushveld Complex; introduction and review,This is the preface to a special issue on various aspects of the Bushveld complex, Transvaal basin, South Africa.

If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.The complex dioritic stocks west of the Malmerbury,,COVID-19 Resources.

Peridotite (Dunite) - University of Auckland

Peridotite (Dunite) Peridotite is a very dense, coarse-grained, olivine-rich, ultra- mafic intrusive rock. It is noted for its low silica content, and contains very little or no feldspar ( orthoclase, plagioclase).It is a common component of oceanic lithosphere, and is derived from the upper mantle.Open Research: The Lindeques Drift and Heidelberg,,The Roodekraal Complex is composed of multiple flows of predominantly mugearite lava with sub-flow intrusions of diorite.

History of Diamonds, Where Do Diamonds Come From

History of Diamonds. The diamond is more than just aesthetically beautiful—it’s an enduring symbol of love, romance, and commitment. The stone’s name is derived from the Greek word adamas, which translates to “unconquerable.” This symbolic meaning lends itself well to the diamond’s historic commemoration of eternal love.
