Geological Mapping

The Regional Geology Department of the Agency primarily carries out geological mapping which is aimed at providing information on the distribution of various rock types present on the country’s landscape. Such information is useful for the identification and development of mineral resources, land use, planning and infrastructural development. It also provides services on sedimentology, stratigraphy, paleontology, palynology, basin analysis, as well as geospatial services on remote sensing and photo interpretation and structural studies.

The continuous mapping on various scales is done, primarily for the determination of the nation’s rock formations for use in all aspects of the government natural resources policies.
