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 analysis
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.

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.

Petrophysical Laboratory
The Geological Survey of Tanzania (GST) has a petrophysical laboratory for measuring petrophysical properties of rock and ore samples. Petrophysical parameters can be used for quantification of geophysical interpretations and have also direct geological applications.

Petrophysical laboratory measurements include density, porosity, magnetic susceptibility and remanent magnetization and galvanic or inductive resistivity.

The GST laboratory equipment has been developed for rapid measurement of many samples with high accuracy. Measured data are currently stored in a database, and data analyses and summaries are available for scientific and commercial purposes.

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.
