For a fine-grained rock collect 100gm of fresh material. For medium-grained rocks collect 250gm samples. For coarse-grained rocks collect 1kg or more of fresh material. Seven working days for full quantitative oxide analysis. A full range of microprobe and scanning electron microscope services are available for the detailed analysis and or imaging of mineral phases.
Costs are dependant on instrument time.
Grain size analysis Grain size of disagregated samples in the 0.1 - 900 micon range is determined using the Coulter LS 130 analyser. Seiving is necessary only where the constituent size is likely to exceed 700 micons. Mineral separation and crushing A wide range of tungsten carbide, zirconia, agate and steel crushing equipment is available to suit most analytical needs. Mozley table, Wilfley table and wet panning techniques are used for separating larger bulk samples. Heavy liquid separations for a wide density range using either organic heavy liquids or sodium polytungstate are available.
