Evidence of wildfires in deep time is preserved as fossilised charcoal fragments the rock record and inertinite macerals coal. Historically, reflectance has been utilised to assess formation temperature these charcoals, thus burning intensities prehistoric fires. This achieved by quantifying variability a function changes microstructure with temperature. Raman spectroscopy shown similarly carbo...
