Said: Although I am not familiar with the Montana coals nor diesel fuel, I do
know that the (higher sulfur) coals here in Ohio have a wide range of d34S
values. For example, samples from one coal seam (the Pennsylvanian-age Lower
Kittanning, No. 5) sampled during one of my studies range from +3 to -14 per
