Geological Mapping

The current regional geological mapping programmes are focused on thematic coverage of the country, project oriented data capture, interpretation and product delivery to our various stakeholders.

Strategic aims of geological mapping

  • To produce basic geo-data and information for mineral exploration, environmental studies and land use.

Standardization and regularly updating of data in order to provide seamless national coverage at any desired scale.

Old mapping and publications

  • Geological maps published at a scale of 1:250,000 as degree sheets (DS 17 Kahama, DS 18 Shinyanga, DS 29 Singida and DS 52 Dodoma). Coverage is 3% of the total 322 QDS divisions of the country
  • Geological maps published at 1:125,000 scale with a coverage of 48% of the total QDS

Present mapping and publications

  • GST is currently mapping and publishing geological maps at a scale of 1:100 000 with coverage of 29% of the total QDS and the maps are available in digital format
  • Geological maps integrate geophysical, geochemical and geological data LandSat images and DEM.
  • Old geological maps are being updated and published by adding value through field checks and incorporating new information (geophysical, geochemical, LandSat images and mineral occurrences)
GST’s mapping programmes produce basic information for the needs of the mineral sector (exploration and mining ventures), land use planning, construction industry, environmental studies and other economic sectors.
GST’s mapping programmes produce basic information for the needs of the mineral sector (exploration and mining ventures), land use planning, construction industry, environmental studies and other sectors of the economy. 85 % of the entire country has been geologically mapped. This has generated basic geological and mineralogical data and information used by investors in the mining sector and other sectors of the economy.
