Rock and sediments

Our methods are capable of analysing a full range of rock materials, igneous, metamorphic or sedimentary, including mineralised material. We can adapt our procedures for pure and applied geochemical applications. A wide range of metallic, industrial and waste minerals can be analysed as either bulk granular material or individual pieces. We are active participants in the GeoPT Proficiency Testing scheme.

Gamma emitting isotopes capability

Natural daughter products from uranium and thorium decay, such as 210Pb, may be used as environmental tracers. Occasionally anthropogenic processes such as oil or gas extraction may pre–concentrate these to hazardous levels i.e. radium in barium sulphate–rich brines. Some of these may be measured using our Canberra Broad Energy germanium gamma spectrometers.

Certain artificial isotopes may be found in our environment or industrial processes due to past nuclear releases, i.e. 137Cs from atmospheric bomb tests or 60Co from steel irradiation. Some of these may be measured using our Canberra Broad Energy germanium gamma spectrometers.
