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
mil.

Some early coal-related sulfur isotope references are included below for your
information:

Hackley, K.C., and Anderson, T.F., 1986, Sulfur isotopic variations in
low-sulfur coal beds from the Rocky Mountain region: Geochimica Cosmochimica
Acta, vol. 50, p. 1703-1713.

Price, F.T., and Shieh, Y.N., 1979, The distribution and isotopic composition
of sulfur in coal beds from the Illinois Basin: Economic Geology, vol. 74, p.
1445-1461.

Smith, J.W., and Batts, B.D., 1974, The distribution and isotopic composition
of sulfur in coal: Geochimica Cosmochimica Acta, vol. 38, p. 121-133.


...I'm sure there are quite a few more out there, perhaps more specific to
your needs.

Ralph.
