Metallogenesis of Selected Gold Deposits in Africa presents the results of investigations jointly performed by the German Geological Survey (BGR), their African counterpart institutions and university researchers.

Subject of the studies were gold deposits in the Palaeoproterozoic domain of Ghana and the Archaean terrains of Zimbabwe and Tansania. The work in Ghana concentrated on vein and lode-type mineralizations in the Ashanti belt, emphasizing the Ashanti mine, placer deposits at Tarkawa and gold occurrences of the Nangodi area.

In Tanzania, the Geita deposit and gold-quartz vein mineralizations in the Nyarkagwe region were considered. The deposits studied in Zimbabwe include the B-rich vein mineralizations at Indarama and Beligwe Star mines, the granitoid hosted Eureka mine near Guruve, the Redwing mine at Penhalonga/Mutare (volcanic hosted) as well as the mineralizations at the Royal Family and Nando Pinkun mines which are hosted in black schists.

The participating working groups have applied a wide range of conventional and novel approaches to study the gold deposits and present models of the genesis of different types of gold mineralizations.

A study of the electrochemical behaviour of gold in water/rock systems and a contribution on the process mineralogy of gold conclude this volume.
