Geological mapping and research has been carried out in Namibia since the early 1900s, resulting in a rather heterogenous information coverage. Also, in the 1990s and early 2000s stagnation of field mapping led to little new data being generated by the Geological Survey, although archival data were captured electronically and made available in digital and hardcopy format. In 2013, a co-operation/contract project between the Geological Survey of Namibia and the Council for Geoscience (South Africa) was initiated to remap the Meso- and Palaeoproterozoic rocks of the Warmbad area, //Karas Region (southern Namibia) - a programme which combined the acquisition of more detailed geological maps and geoscientific research with training and capacity building at both the Namibian and South African geological surveys. Its initial contract fulfilled, the project's activities expanded to other parts of the highly prospective //Karas Region, and over the following decade produced ninety-five 1:50 000 scale geological maps, with accompanying reports and associated geochemical, geochronological and structural data, plus a number of research publications, conference abstracts and post-graduate theses.
