Biogeochemistry SGS has considerable experience in the preparation and analysis of a wide range of vegetation samples. Such samples may be dried and macerated or ashed prior to acid digestion and analysis by ICP-OES (GE_ICP23D50) and ICP-MS (GE_IMS23D50).

Lithogeochemistry Lithogeochemical analysis is used for basic rock characterisation based on major, minor and trace element chemistry. It requires whole rock analytical methods to ensure that refractory minerals such as zircon and chromite are fully dissolved. Lithogeochemical analysis may be used in exploration programs for identification of different rock types that might occur in drill core or at outcrop, particularly when primary lithologies are obscured by subsequent alteration or metamorphic events. Lithogeochemical analysis is also used by geological surveys undertaking geological mapping projects, by researchers studying geological, geochemical and petrological processes and by oil companies requiring complete rock characterization for calibrating core responses to borehole sensors.
