South Africa is the country at the southernmost corner of Africa. Cape Town, the capital, is named after the Cape, the southernmost point of the African continent. This country has numerous famous geological features, which are rather easy to visit, because of the dry
The geology of South Africa is highly varied including cratons, greenstone belts, large impact craters as well as orogenic geology of the country is the base for a large mining sector that extracts gold, diamonds, iron and coal from worldclass deposits. The geomorphology of South Africa consists of a high plateau rimmed to west, south and southeast by the Great Escarpment and rugged
Over 50% of all gold reserves are found in South Africa, with the Witwatersrand Basin remaining the largest gold resource in the world.. In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2010, however, China affirmed its status as the worlds largest gold producer with production of 324 tonnes of gold, followed by Australia ( tonnes), and South Africa

progression of classification of gold deposits related to magmatic rocks as commencing with the term porphyry gold deposits (after the usage of porphyry copper deposits) in 1992 by Hollister. This ignores the fact that Sillitoe (1979) had earlier introduced the concept of a porphyry gold deposit style.
#0183;#32;The Pala gold region, southwestern Chad, hosted in the Precambrian Mayo Kebbi formations (Kasser, 1995, Penaye et al., 2006), contains several occurrences of orogenicgold deposits. The region of the Pala has long been known for its gold occurrences ( Chaussier, 1970, Djekoundam, 1995, Kasser, 1995, Kusnir and Moutaye, 1997, Mamat Boka, 2010, Deudibaye,
#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).
South Africa South Africa Gold mining: Prospectors established in 1886 the existence of a belt of goldbearing reefs 40 miles (60 km) wide centred on presentday Johannesburg. The rapid growth of the goldmining industry intensified processes started by the diamond boom: immigration, urbanization, capital investment, and labour migrancy. By 1899 the gold industry attracted investment worth
Banded iron formationhosted gold deposits are attractive targets thanks to their potential for large, districtscale gold mining.
