Unveiling Namibia’s Geological Canvas

The Regional Geoscience Division of the Geological Survey of Namibia (GSN) plays a vital role in understanding and mapping Namibia’s diverse geological history. Our division encompasses four key subdivisions: Tectonics, Stratigraphy, GIS & Remote Sensing, and Cartography. Through a combination of field studies, data analysis, and map production, we provide a comprehensive picture of Namibia’s geological makeup.

By collaborating with the Regional Geoscience Division, you can gain valuable insights into:

Namibia’s geological history and evolution. The distribution of mineral resources and potential exploration targets. Sustainable land use practices and environmental management strategies.

Contact the Regional Geoscience Division today to learn more about our expertise and ongoing projects.

Tectonics Subdivision

Focus

  • The Tectonics Subdivision delves into the oldest rock formations in Namibia, dating back to the Palaeo- to Neoproterozoic orogenic belts.

Activities

  • Creates and maintains a simplified tectonostratigraphic map showcasing the country’s major tectonic and stratigraphic domains.
  • Collaborates with the Council for Geoscience (CGS) of South Africa on high-resolution geological mapping, particularly in Southern Namibia.
  • Integrates modern remote sensing data (ASTER, Hyperspectral, Sentinel-2, Google Earth) and geophysical data into geological mapping projects.
  • Supports research initiatives, contributing to university theses and publications.

Stratigraphy Subdivision

Focus

  • The Stratigraphy Subdivision concentrates on the younger geological layers, spanning the Palaeozoic to Cenozoic sedimentary basins, including offshore areas.

Activities

  • Mapping Quaternary to Recent surficial sediments (regolith) in northeastern Namibia. This project aims to identify potential resources like uranium, gypsum, and water, while also aiding in land use planning and environmental assessments.
  • Mapping Quaternary to Recent surficial sediments of the Oshakati sheet, utilising remote sensing techniques for efficient data analysis.
  • Detailed mapping of Cenozoic fluvial and marine terraces along the Skeleton Coast, focusing on understanding their economic potential, particularly for diamond exploration.

GIS and Remote Sensing Subdivision

GIS and Remote Sensing Services

  • Data Capture and Compilation: We collect and compile field data acquired by GSN staff or obtained from external sources.
  • Geological Map Database: We maintain and update the geological map database, ensuring its accuracy and accessibility.
  • Digital Data Analysis: We analyse digital geological data to produce thematic maps and reports.
  • Remote Sensing Applications: We utilise aerial photographs, orthophotos, satellite images, and hyperspectral data to enhance geological mapping, especially in arid regions

Cartography Subdivision

Key Activities

  • Looking for a geological map? The Cartography Subdivision can help! They offer a variety of geological maps at scales ranging from 1:25,000 to 1:1,000,000, providing detailed information on Namibia’s geological composition.
