Few measurements of the D/H ratios in liquid and solid fossil fuels have been made. Additional isotopic data are reported here in the form of D/H and 13C/12C ratios for crude oils and brown coals which occur together in the Bass Strait region of Australia. Studies of petrographic fractions of these coals and of the changes in the isotopic composition of coals and coal extracts with increasing maturity show that the original D/H ratios characteristic of contributing plant materials are more readily erased and homogenized during early diagenesis than the corresponding 13C/12C ratios.
