The thermodynamic approach proposed is purely supply side and is expressed in GJ/t. A mineral can be considered very rare and thus "thermodynamically critical " whereas when using only the consumption side other factors come into play such as declining in consumption due to better substitutes or disuse phase out of technology etc.
