The Geological Society of South Africa (GSSA) is a learned society for geological science that was founded in 1895, making it one of the oldest such societies in Africa. The GSSA publishes the peer-reviewed scientific journal, the South African Journal of Geology, and annually awards the Draper Memorial Medal (in honour of David Draper) to recognise achievement in geology, and the Des Pretorius Memorial Award (in honour of Desmond Pretorius) to recognise exceptional work on economic geology in Africa. The GSSA collaborates internationally with other professional organizations such as the European Federation of Geologists (EFG). Source: Wikipedia (en)
