Figure 4From: Comparison of vitrified and unvitrified Eocene woody tissues by TMAH thermochemolysis – implications for the early stages of the formation of vitriniteThermochemolysis-GC-MS data for four discrete analyses of vitrified root tissue, illustrating run-run variability/reproducibility. Data were obtained from multiple analyses of a single sample. * = Contaminant (primarily septum bleed).Back to article page
