The BIFhosted Amalia gold deposit is located in the Amalia greenstone belt, about 325 km WSW of Johannesburg, South Africa. The Amalia greenstone belt forms part of the AmaliaKraaipan greenstonegranitoid terrane in the Kimberley Block of the Kaapvaal craton (Fig. 1). The poorly exposed AmaliaKraaipan greenstone belts are aligned close to a
The Formation of Gold deposits in South Africa. South African ''Gold Rush'' Nugget Mounted on a Gold Bar Brooch and a piece: At a first glance, the Witwatersrand basin, the largest known gold resource on our planet, is not automatically related to ocean research.
In 1852, the English prospector Davis discovered the first gold in the Witwatersrand, leading to the South African gold rush and the discovery of much more gold deposits within the basin. Although the Witwatersrand has been subject for decades of research, the genesis of gold and uranium ore is

17/10/2019#0183;#32;The gold fields of the Witwatersrand Basin in South Africa are, by a landslide, the largest single gold producing district in the world. It has produced some 2 billion ounces over a century of mining and at an average grade of 15 g/t Au with a current head grade of 610 g/t Au and they still have estimated reserves of some 1,161 billion ounces (36,000 tonnes). Production does not come easy

South Africa''s gold ore reserves in the Witwatersrand Basin, a gold placer deposit, with gold hosted by conglomerates and grits, has been mined for more than 100 years but remains the greatest unmined source of gold in the world. The Witwatersrand is underlain by an underground geological formation also known as the Witwatersrand Basin. It lies
The Blue Dot gold deposit, located in the Archean Amalia greenstone belt of South Africa, is hosted in an oxide (#177; carbonate) facies banded iron formation (BIF). It consists of three stratabound orebodies; Goudplaats, Abelskop, and Bothmasrust. The orebodies are flanked by quartzchloriteferroan dolomitealbite schist in the hanging wall and mafic (volcanic) schists in the footwall

This depression was then flooded by an igneous intrusion from the mantle. Some layers of the Dominion Group contain gold deposits, which have been mined with minor success. Not much else about the Dominion Group is known, as this all happened a very long time ago and there are few places where the rocks are wellpreserved. In the Vredefort area
It is thought that the sediments of the Dominion group were deposited about billion years ago, in a rift valley that was formed when the crust under the craton began to stretch. This depression was then flooded by an igneous intrusion from the mantle.
