The early Cretaceous Koegel Fontein intrusive complex is situated near the Atlantic coast in South Africa, about 350 km northwest of Cape Town. The complex comprises felsic units of granite and syenite with compositionally related dykes, and a single intrusive plug of diorite.

South Africa has a complex geological history dating back millions of years, and some of the oldest rocks on earth have been found here. Many geological formations in South Africa are rich in mineral deposits such as the Witwatersrand quartzites (gold), the Bushveld Igneous Complex (platinum) and the coal deposits found in formations of the Karoo
2. Materials and methods Swaziland lies in the subtropical region of Southern Africa. It is located at the eastern declivity of the South African Great Escarpment and its slope to the Indian Ocean between 25"43' and 27"19'S and 30"44' and 32"08'E.
Diorite is the stone which always in dark colors, such as black, gray or light green with dark is mainly composed of plagioclase and one or more dark minerals. Dark minerals are mainly amphibole, others such as pyroxene and biotite, the total is generally 20 to 35%.
deposits in New South Wales, principally in skarns within aureoles of hightemperature granites. There are many known occurrences in the Lachlan and New England orogens (Figure 16). Newly available highresolution aeromagnetic data over most of the prospective areas should allow opportunities for such deposits to be readily assessed.
western part of the Cape Province (Namaqualand), South Africa (Fig. l). In the past, these occurr€nces were often collectively referred to as norites or noritoids, even though the most prevalent rock types are anorthosite and diorite. The relatively recent formal term "Koperberg Suite" (Marais, 1980) is derived from the name of a historical

La ceinture de diorite de Barberton, aussi connue sous le nom de Makhonjwa Mountains (zone qui comprend 40 % de la ceinture de diorite ), est située sur le bord oriental du craton du est connue pour contenir de l'or ainsi que pour sa komatiite, une roche volcanique ultramafique rare, nommée d'après la rivière Komati qui coule dans la zone.
Association of South Africa. INTRODUCTION Around 1885 the ore deposit of the Albert Silver mine was discovered and production continued intermittently until 1914 (Robb, Robb, and Walraven 1994). The Albert Silver mine is situated on the farm Roodepoortjie 250JR, north of Bronkhorstspruit, some 80 km eastnortheast of Pretoria in
Okiep lies 8 kms from Springbok and until mining ceased in 1918 was known to have the richest copper deposits in the world. Okiep is also the oldest mining town in South Africa. An artefact from the early boom years is the Cornish Beam Pump (now a national monument) which was built in 1882 to pump water from the mine.
The Cerro Corona mine is located in northern Peru on the eastern slope of the western mountain range of the Andes. This is achieved by a combination of a higher density factor for the tailings plus an increase in the dam wall of the current tailings dam to 3,803m amsl, which adds two years to the existing TSF, and the inpit tailings solution adds another five years life.
The Roodekraal Complex is composed of multiple flows of predominantly mugearite lava with subflow intrusions of diorite. The diorite of Lindeques Drift and the lava and diorite of Roodekraal are chemically comparable in terms of both major and trace elements, suggesting a comagmatic derivation.
The Bushveld Igneous Complex (BIC) is a large layered igneous intrusion within the Earth's crust which has been tilted and eroded and now outcrops around what appears to be the edge of a great geological basin, the Transvaal Basin. Located in South Africa, the BIC contains some of .

Gabbro is a dark grey to black, coarsely crystalline, plutonic, basic igneous rock, rich in Fe, Mg and Ca, low in SiO 2 [4553%]). There are many varieties which variously contain Carich plagioclase feldspars (labradorite to anorthite), Fe, Mg, Ca varieties of pyroxene (augite .
May 13, 2013· South Africa is host to a large succession of sedimentary carbonate rocks within the geological column. They range from Swazian (>3090Ma) to quaternary in age and are variably composed from pure calcium carbonate (limestone) to 46 percent magnesium carbonate (dolomite).
The Ookiep CopperSilver Mine is near Springbok, South Africa. The site was first discovered in 1685 by Expedition Commissioned By Governor Simon Van Der Stel. The Ookiep CopperSilver Mine is a underground mining operation. Initial production took place .
