      Other articles where Bushveld Complex is discussed: Africa: The Precambrian: 2 billion years ago the Bushveld Complex—which is one of the largest differentiated igneous bodies on Earth, containing major deposits of platinum, chromium, and vanadium—was emplaced in the northern Kaapvaal craton. The middle part of the early Proterozoic was dominated by powerful orogenic (mountain-building.   This guide negates the need to carry more than one guide book when travelling to any southern African Bushveld region. In writing this book Lee has availed himself to the services of many experts who have read and verified facts in their individual areas of expertise, including: Vincent Carruthers and Louis du Preez (amphibians), Jonathan Reviews: 5.

      Bushveld Complex. The economic potential of many ore deposits is difficult to evaluate,but this is not so in the case of the Bushveld ores. The Bushveld Complex (see Figure 2) is an enormous irruption of magma (molten rock) sourced deep within the Earth. The extent of the magma flow was at least km in diam-eter. In the order of 1 million. Geologic Setting Regional geology The Bushveld Complex is of enormous extent (Fig. 1).

The Platreef is one of the world's largest primary deposits of platinum-group elements (PGE) with significant associated reserves of Ni and Cu, amounting to ∼30 percent of in situ value at prices (Naldrett, ).It is located in the northern limb of the Bushveld Complex in South Africa and unlike stratiform reef-type deposits such as the Merensky Reef or the UG2 chromitite of the.

The exposed northern limb of the Paleoproterozoic Bushveld Complex has a NS-oriented sinuous outcrop. CHAPTER Two: OVERVIEW OF THE BUSHVELD COMPLEX. General The Bushveld Complex is the largest known layered intrusion on Earth, with an outcrop area of over km. and further sub-outcrops of km.

Regional variations in. The Bushveld Complex is a large layered igneous intrusion located in the northern part of South Africa ().It was discovered in the late 19th century and was first described in detail in (Molengraaff, ).The discovery of the host rocks of the major platinum deposits in (Cawthorn, ), moved the Bushveld Complex from being an interesting geological phenomenon to an.

The Bushveld Complex and its tectonic setting. The Ga (Scoates and Friedman, ) Bushveld Complex (Fig. 1) is the world's largest layered intrusion, with an areal extent of ~ 65 km 2 (Eales and Cawthorn, ).

It is also host to the largest known deposits of Cr, V and platinum group metals (PGM) on Earth. Fig. 1 indicates the location of Welgegund within a regional southern African context and the extent of the Bushveld Complex ore deposits (greyscale areas on the southern African map). Additionally, in the zoomed-in map, the locations of large pyrometallurgical smelters in the wBC, the Johannesburg-Pretoria (Jhb-Pta) megacity (Lourens et al., ) and large atmospheric point sources.

The Bushveld Igneous Complex is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.

It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs. The Bushveld Complex comprises the Rustenburg Layered suite, the Lebowa Granites.

The eastern limb of the Bushveld Igneous Complex outcrops in the Middleveld, a localized physiographic region of northeastern South Africa associated with. For detail on the regional setting and geological map see the Bushveld Complex overview record.

The Potgietersrus Limb extends for more than km in a north-south direction. The base of the Bushveld mafic suite transgresses from the Pretoria Group quartzites and shales, through the Penge Iron Formation and Malmani Dolomite to basement granite gneiss in the north.

The complex is part of the plume-related and laterally extensive Ga Meeline Suite, the intrusive component of a large igneous province. It is an anhydrous tholeiitic suite consisting of five.

Subdivision of the Bushveld Complex The Bushveld Complex can be subdivided into five compartments (Fig. 3): (1) a far western or Nietverdiend compartment, (2) a western com- partment, (3) the Villa Nora-Potgietersrust com- partment, (4) the eastern compartment, and (5) the covered Bethal compartment, and in addition the Molopo Farms Complex in Botswana, which is correlated with the.

The mafic rocks of the Bushveld Complex crop out in four geographically discrete areas in South Africa, with a further body totally hidden under younger sedimentary cover ().Several studies on different parts of the complex, using different minerals, and using different age-dating techniques give ages of about Ma (Walraven, ).It was intruded into the intercratonic sedimentary rocks of.

Descriptions of major ore deposits world wide. The Kroondal and Marikana platinum mines are located on the south-western and southern limb of the western lobe of the Bushveld Complex, ~km NW of Johannesburg, and to the immediate NE and east of the town of Rustenburg in the Northwest Province of South Africa.

Bushveld Complex. The mines are extracting the PGE minerals, which comprise Platinum, Palladium, Rhodium and Gold, together with base metals Copper and Nickel. This article focuses on the description of the aquifer systems associated with the Bushveld Complex’s mafic and ultramafic rocks and attempts to characterise the shallow.

The mafic rocks of the Bushveld Complex, South Africa, were emplaced into a stable cratonic shield some b.y. ago, and have remained remarkably well preserved from deformation, metamorphism and low temperature alteration, at least partly by.

The Bushveld Complex in South Africa is the largest mafic-ultramafic layered intrusion on Earth, and hosts the Rustenburg Layered Suite. This layered series crops out as discrete limbs arranged in a circular fashion.

The two major exposures, with a length of approximately km, are the Western and the Eastern limbs.Bushveld Energy brings the energy storage value chain to South Africa by leveraging the Company’s South African-mined and beneficiated vanadium.
