The Bosumtwi impact structure in Ghana is among the most recent (1.07 Myr) large impact crater structures (10.5 km in diameter), and probably one of the best-preserved terrestrial meteorite craters, with ejecta materials in the form of suevite deposits outside the crater rim. Suevite is defined (Stöffler and Grieve 1994) as polymict impact breccia

granite–greenstone terrane which hosts significant gold mineralisation in Ghana and Burkina Faso. Based upon structural observations, the timing of gold mineralisation is late in the first phase of deformation after all host lithologies were in place. The deposit is within an oblique, dextral structure in a regionally extensive deformation zone.

Birimian in Ghana is defined by a series of SW‐NE trending granite‐greenstone gold belts, which are much better exposed in southern and western Ghana, with the gold belts defined from south to north as the Kibi‐Winneba, Ashanti, Sefwi‐Bibiani, Bui, Bole‐Bolgatanga and Lawra (which trends N‐S).
Ghana is thus well endowed with substantial mineral resources, the major ones being gold, diamonds, manganese and bauxite. Gold is the predominant mineral produced in the country, accounting for over 90% of all mineral revenues annually over the past two decades.
