    Note 1 to entry: In the geological coalification sequence, the transformation from peat to coal is defined as occurring when the total in-situ moisture content has decreased to 75 % by mass. The upper limit for undisturbed coal seams in the normal coalification process leading to semi-graphite is defined as corresponding to a mean random vitrinite reflectance,,of 6,0 % or, preferably, a mean
