Geo Information
GST has for the past 80 years being conducting geo-surveys and research activities in the country, generating substantial amount of geoscientific data and information on the Earth’s crust and its natural resources.

The available information include the following

  • Vast geological, geophysical and geochemical information, which can readily assist investors in the mineral sector in selecting prospective areas for search of minerals.
  • Geological maps covering 85% of the 322 Quarter Degree Sheets (QSD) of Tanzania. Twenty nine percent (29%) of the maps are at 1:100,000 scale, 48% are at 1:125,000 scale, 3% are at 1:250,000 scale and 5% of the geologically mapped QDS are not yet published.
  • Other geological maps include: Block maps of the Lake Victoria Goldfields, Kigoma-Mpanda and Lake Rukwa areas at a scale of 1:500,000.
  • Geological map of Tanzania showing the geology and mineral occurrences
  • Countrywide airborne geophysical map coverage of magnetic and radiometric surveys.
  • High resolution airborne geophysical surveys data for selected areas around Lake Victoria Goldfield (Kahama, Biharamulo, and Mara) and Mpanda Mineral Field.
  • Regional geochemical survey data for selected areas collected by GST, exploration companies and other institutions
    GST hosts extensive geoscientific data stored in soft and hard formats. Hard copies include unpublished reports, field notes, maps and observation data resulting from studies carried out by GST and other geoscientific institutions collected from 1885 to present. Hard copy material may be studied by physically visiting the Archive office and can be photocopied or scanned. All the services are charged (price list) .

    Among the tasks of GST is to make this geoscientific information and data easily available and accessible to stakeholders and the public. The target of GST is to make downloadable maps and full-text documents through the internet (price list) . The aim is to make customers able to browse geological information in a map server or search the catalogues of printed map series for easy access of GST information.

    The national depot for drill cores located at Dodoma about 5 km from the town centre now holds over thousands of meters of drill cores from different parts of the country. The target is to collect more drill cores from exploration and mining companies operating in the country for safe custody.
