Strategic aims of geological mapping

• The current regional geological mapping programme is focused on more thematic, project oriented data capture, interpretation and product delivery aimed at maximum attraction to the stakeholders.
•  Main focus to produce basic geo-data and information for mineral exploration, environmental studies and land use
• Standardization and regularly updating data to provide seamless national coverage at any desired scale.
• Mapping of mineral resource targets according to areas with high potential for investment.

Past 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(see index map)
• 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)
