1. Calculated maturity (vitrinite reflectance values: Sweeney & Burnham 1990) at the top of the Namurian–Visean unit over four time steps: (a) Late Carboniferous; (b) Late Triassic; (c) Late Jurassic and (d) the present day.
Calculated maturity (vitrinite reflectance values: Sweeney & Burnham 1990) at the top of the Namurian–Visean unit over four time steps: (a) Late Carboniferous; (b) Late Triassic; (c) Late Jurassic and (d) the present day. (e)–(h) The calculated transformation ratios for the same time steps as above. The calculated transformation ratios are based on Burnham (1989) TIII for the Namurian–Visean source rock.
