Hi. I am a geologist working with the conodont colour alteration index (a rock thermal maturity indicator) which follows the Arrhenius equations. This graph corresponds to Rejebian et al. (1987), the authors who calibrated the color alteration index after laboratory experiments.
I was wondering if it is possible to obtain the parameters of the Arrhenius equations from this graph, in order to introduce them in an excel spreadsheet.
Thank you very much
