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.
Services offered include: sample preparation, fire assay and wet chemistry analysis. The chemical laboratory performs a wide range of determinations, which include:
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:
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.
