Calculation of oxygen levels from the studied areas based on the model proposed by Glasspool et al. (2015). The oxygen curves have been calculated from the inertinite in coal data from Glasspool and Scott (2010) and Glasspool et al. (2015). S-shaped curves are assumed to ensure smooth transition from 0% inertinite to 100% inertinite of total macerals. Three curves represent the minimum, best and maximum estimate from left to right, respectively
