The Palynology Laboratory is located in the Department of Geology and Geological Engineering at Colorado School of Mines. The laboratory conducts pollen-based research which represents an important tool in stratigraphy, paleoenvironmental studies, archaeology, and forensic investigations. In addition, the laboratory offers loss-on-ignition analysis.

Loss-on-ignition is a test widely used in geochemistry to determine the volatile content of rocks, soils, lake sediments, and other materials. Samples are heated at a specified temperature allowing volatile substances to escape. The heating is done in air to oxidize the samples.
The laboratory offers two different types of loss-on-ignition analyses for organic-rich samples such as soils and lake sediments. The organic carbon content of the samples is determined through loss-on-ignition analysis at 550°C. The inorganic carbon content is measured through ignition at 950°C. The analyses are performed following the protocol of Heiri et al. (2001).
The volatile loss of powdered whole-rock samples is determined at 1050°C. This method is most widely used in the geochemical analysis of rocks and supplements whole-rock major element data determined by X-ray fluorescence or other techniques.
