Geological Map of Area 2114 Omaruru, Namibia

This map is part of the 1:250,000-scale geological map series of Namibia and extends from the coastal plain to the central highland. The rocks exposed in the area span more than 1.5 billion years of geologic history. The oldest Paleoproterozoic gneisses (circa 1,600 million years) are followed by the metasediments and associated intrusives of the Pan-African Damara Fold Belt (720 to 480 million years) and the Mesozoic Karoo Sequence (290 to 200 million years). Post-Karoo volcanics and intrusives such as the Brandberg (circa 100 million years) are related to the opening of the South Atlantic Ocean beginning during the Jurassic period, while the youngest deposits of the area are formed by the Quaternary to recent sands and calcretes of the Namib Desert. This map was compiled and printed in cooperation with the Geological Survey of Finland.
