		A craton (kratos; Greek for strength) is an old and stable part of the continental crust that has survived the merging and splitting of continents and supercontinents for at least 500 million years.
		Cratons are generally found in the interiors of continents and are characteristically composed of ancient crystalline basement crust of lightweight felsic igneous rock such as granite.
		The term craton is used to distinguish the stable interior portion of the continental crust from such regions as mobile geosynclinal troughs, which are linear belts of sediment accumulations subject to subsidence, or downwarping.

		A craton is an old and stable part of the continental crust that has survived the merging and splitting of continents and supercontinents for at least 500 million years.
		Cratons are generally found in the interiors of continents and are formed of a crust of lightweight felsic igneous rock such as granite attached to a section of the upper mantle.
		Cratons are subdivided geographically into geologic provinces, each province being classified as an Archon, a Proton or a Tecton according to its age:

		The Congo craton, covered by the Palaeozoic-to-recent Congo basin, is an ancient Precambrian craton that with four others (the Kaapvaal, Zimbabwe, Tanzania, and West African cratons) makes up the modern continent of Africa.
		These cratons were formed between about 3.6 and 2.0 billion years ago and have been tectonically stable since that time.
		In Late Neoproterozoic time, the Congo craton was a low-lying platform the size of thee conterminous United States.

		Sedimentation on the São-Francisco Craton comprises the Espinhaco Group, which is interpreted as a continental rift- and sag-basin, while coeval sedimentation on the opposite side of the Atlantic Ocean is known as the Chela Group of southern Angola.
		Further inboard of the Congo Craton, additional continent-dominated sequences occur in the Kibaran and Irumide belts, and on the Bangweulu Block.

		Congo is a name shared by two neighbouring countries in Central Africa, usually distinguished either by using their full official names or adding their capitals:
		The Democratic Republic of the Congo is sometimes known as "Congo-Kinshasa" or simply DRC.
		It was once the personal property of King Leopold II of Belgium, when it was known as the Congo Free State, and later a Belgian colony when it was renamed the Belgian Congo.

	Kalahari craton - Wikipedia, the free encyclopedia
		The Kalahari craton occupies a large portion of South Africa and consists of the Kaapvaal, the Zimbabwe craton, the Limpopo belt, and the Namaqua Belt.
		Additional crust was formed and reworked along all of the craton’s margins at 1.4–1.0 Ga. To the north, the Damara-Lufilian-Zambezi Fold Belt separates the Congo craton to the north with the Kalahari.
		Along the southern margin, the Namaqua–Natal–Maud belt underwent arc magmatism, terrane accretion, polyphase amphibolite- to granulite-grade contractional/transpressional deformation, and late-syntectonic granite intrusion at 1.38–1.0 Ga. A largely buried orogen along the western margin records amphibolite-grade deformation and granitoid plutonism at 1.35–1.2 Ga and is inferred to connect with the Namaqua belt to the south.

	GEOLOGY
		The Congo craton occupies a large part of central southern Africa; its oldest rocks occur in the Tanzania province, an area of granitic basement and greenstone belts similar in structure to the Rhodesian province.
		The final stages of activity in the craton were marked by the deposition of late Precambrian sediments, laid down unconformably on the stabilised craton.
		The West Congo belt is a sedimentary succession, similar to the Katanga system, which runs N-S for 1,000 km/620 mi along the W side of the Congo craton.

	Congo could turn out to be a gold mine - MSN Money (Site not responding. Last check: 2007-11-06)
		Substantial mining before the civil war that made the Congo too dangerous to explore has shown conclusively that the Central African copper belt holds at least 5 billion tons of copper and as much as 40% of the world's cobalt reserves.
		In this case, it is in equatorial areas where large cratons –- blocks of the Earth's crust -- have contracted and formed rich mountainous belts.
		Banro is focused on an area wedged among the Congo Craton to the west, the Tanzania Craton to the east and the Zimbabwe Craton to the south.

		Moreover, the CAFB is suspected to be the locus of the suture zone that separates the Congo craton from its cratonic neighbours.
		The Congo craton in Cameroon consists of the Archaean Ntem Complex and of the Palaeoproterozoic Nyong Complex.

		The Neoproterozoic-Lower Palaeozoic Katangan sedimentary sequence occurs at the southern margin of the Congo Craton, between the Democratic Republic of Congo and Zambia.
		Subsequent orogenesis between the Zimbabwe Craton to the south and the Congo Craton to the north resulted in northward-oriented thrusting and elevation of nappes with the Katangan sedimentary strata.
		Rifting between the Zimbabwe Craton and the Congo Craton, followed by a marine transgression, led to the deposition of the Roan Group continental and shallow marine proximal clastics supplied from the cratonic source in the north and grading to distal carbonate facies in the south.

		No "Kibaran" aged basement has been recognised in NW Zambia, and the basement is interpreted to form part of the Congo craton (refer to Key et al., 2000, Journal of African Earth Sciences).
		Samples collected from a total of eight sites have yielded two separate remanences, which will help constrain the position of the Congo craton at around 760 Ma and possibly at the peak of Lufilian orogeny at 550 Ma.

		The Congo craton occupied equatorial latitudes at 765-750 Ma, suggesting that the diamictite, the `Grand Conglomerat', and other Sturtian glaciogenic rocks in the Congo craton, represent a low-latitude glaciation.

	Mining Review Africa - Issue 2/2004
		The Congo Craton, covered by the Palaeozoic to recent Congo basin, is Africa’s largest under-explored region in terms of Archaean geology, and in addition to the Kasai region of the DRC, extends into Sudan as well as into Angola’s traditional diamond producing region that includes the Lunda Norte kimberlites.
		In the days of Belgian colonial rule, a great deal of mining was undertaken, and it is estimated that 50 tonnes of gold were produced from the northern part of the Congo Craton, which includes the Kilo-Moto mine.
		The Kasai region features a high-grade metamorphic showing that has been excluded from greenstone searches, and the Congo Craton in general is a vast area that has not had any recent geological mapping done.

	Geologic Framework
		Convergence between the São Francisco – Congo, Amazonian and Rio de La Plata Cratons during the assembly of West Gondwana generated two major Neoproterozoic belts: the Brasília and Ribeira belts (see Cordani et al., 2000; and Heilbron et al., this volume, for a full description of the geology of the belts).
		Like the Brasília belt, the Central Ribeira belt (Figure 1), across the states of Rio de Janeiro and São Paulo, is a result of convergence between the São Francisco Craton and some Neoproterozoic fragments, and the Congo Craton.
		Major collision of the Ribeira belt with the Sao Francisco Craton was accompanied by an important tectono-thermal event dated between 590 and 565 Ma (Machado et al., 1996), interpreted to be associated with thrusting and development of dextral shear zones.
