Bushveld Igneous Complex geologic map and mine locations. The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion [1] [2] within the Earth's crust. [3] It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.
The Bushveld (from Afrikaans: bosveld, ... The complex includes the Merensky Reef, which is the world's biggest source of platinum as well as platinum-group metals.
Mines of the Merensky Reef. The Merensky Reef is a layer of igneous rock in the Bushveld Igneous Complex (BIC) in the North West, Limpopo, Gauteng and Mpumalanga provinces of South Africa which together with an underlying layer, the Upper Group 2 Reef (UG2), contains most of the world's known reserves of platinum group metals (PGMs) or platinum group elements (PGEs)—platinum, palladium ...
Chromitite and anorthosite layered igneous rocks in Critical Zone UG1 of the Bushveld Igneous Complex at the Mononono River outcrop, near Steelpoort, South Africa. A layered intrusion is a large sill-like body of igneous rock which exhibits vertical layering or differences in composition and texture.
The reserve includes a variety of landscapes including slopes, cliffs, crests, kloofs, rivers, wetlands and valleys. Although the area covers a diverse geological area, it consists mainly of the Magaliesberg mountain complex comprising two geological formations: the Transvaal System and the Bushveld Igneous Complex. These formations contain the ...
Arthur Lewis Hall FRS (10 January 1872 – 13 August 1955) was a British geologist, who worked in South Africa for most of his career. He was awarded the Murchison Medal of the Geological Society of London in 1930 for his work on the Bushveld Igneous Complex, and elected to the Royal Society in 1935.
The Transvaal Supergroup displays three unconformity-bounded sequences that surface in two geographically distinct areas – the Transvaal Basin, which circumscribes the Bushveld Igneous Complex, and the Griqualand West basin, lying between Kimberley and Sishen at the western Kaapvaal craton rim, extending into southern Botswana beneath the ...
In the Bushveld Igneous Complex, two orebodies, the Upper Group 2 (UG2) and the Merensky Reef, host about 70% of the world's platinum group metals (PGM), and pose major extraction problems for the mining industry in their faults, dykes, joints, domes, iron-rich ultramafic pegmatoids, rolls and dunite pipes. The greatest mining problems, though ...
