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Hard copies include unpublished reports, field notes, maps and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.
