The
GST
laboratory
is
among
the
leading establishment in the country
undertaking chemical, mineralogical, petrological analyses of mineral,
soil, rock and water samples. It also provides services on
environmental studies and mineral beneficiation tests.
GST
Laboratory
has
developed
a
Quality Assurance System (QAS), which
complies with the ISO/IEC 17025-General Requirements for the Competence
of Testing and Calibration Laboratories.

Chemical analyses |
|
Services offered include: sample
preparation, fire assay and wet chemistry analysis. The chemical
laboratory performs a wide range of determinations, which include:
- Major elements (SiO2, Al2O3,
TiO2, P2O5, CaO, Fe2O3, K2O, MgO, MnO and Na2O.
- Base metals (Pb, Zn, Ni, Cu).
- Trace elements (Ag, As, CO,
Cr, Cu, MO, Ni, Pb, Zn, Au, Hg).
- Precious metals (Au, Ag).
- Water analysis (both clean
and waste) for various components such TDS, sulphates, conductivity,
salinity, pH, turbidity, colour and cations are analysed in water
colour.
- Pollutant elements (metals)
such as: mercury, lead, zinc, cadmium, arsenic and selenium.

Petrological and
mineralogical studies
|
| The Mineralogy and
petrology laboratory section is equipped with modern facilities for
sample preparation, analyzing different minerals, rocks and
identification of gemstones. The laboratory offers services on
preparation of thin and polished sections, micropetrographic studies
and gemological studies. |
Lapidary |
|
The laboratory offers services
for rock cutting and polishing as per customer demand. The laboratory
cuts and polishes specimens for dimension and decoration stones.

training institutions as teaching materials (see price list) . |
Petrophysical
measurement
|
|
Petrophysical properties of
rocks are essential for interpreting geophysical measurements and in
assessing geochemical, mineralogy and geophysical constituents of
rocks. The Geological Survey of Tanzania (GST) undertakes petrophysical
measurements for determining petrophysical properties of rock and
ore samples.
The following petrophysical
measurements are undertaken:
- Magnetic susceptibility of
rocks
- Remanent magnetization
- Q – ratio calculation.
- Rock density.
- Rock conductivity.
