A major frustration in thermal maturation modelling for petroleum exploration in Australian sedimentary basins is the inconsistency between the values of different thermal maturity indicators. Vitrinite reflectance (VR) , Rock-Eval Tmax , spore colouration index (SCI) and fluorescence alteration of multiple macerals (FAMM) for wells from three Australian basins show inconsistencies due to technical, methodological and conceptual problems inherent in each technique. When the differences between the concepts of rank and thermal maturity are considered, it can be shown that some inconsistencies are more apparent than real. It is important to consider this distinction when selecting data against which to model burial and thermal histories.
