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, Afrikaans: bos 'bush' and Afrikaans: veld) is a sub-tropical woodland ecoregion of Southern Africa. The ecoregion straddles the Tropic of Capricorn and constitutes the southern part of the Zambezian region .
These extruded rocks, containing minerals such as vanadium and platinum, are called the Bushveld Igneous Complex. The original extent of this rock upthrust involved about 250,000 square kilometres, and is sometimes called the Waterberg Supergroup. Sedimentary deposition from rivers cutting through Waterberg endured until roughly 1.5 billion ...
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 ...
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.
It is delimited by the Witwatersrand Basin (2,700 Mya) and the Bushveld Igneous Complex (2,050 Mya). It consists of three parts, the Transvaal Basin in the east; the Griqualand Basin in the west; the smaller Kanye Basin in southern Botswana.
