- W1982557104 abstract "The distribution of metalloporphyrins in some petrographic components of a subbituminous coal (Janina, East High Silesian coal basin, Poland) were determined. The coal selected contains both iron and gallium porphyrins, and the concentration of each type was estimated in vitrain and durain. The gallium porphyrin content appeared to parallel the amount of vitrinite in the sample, but no correlation between iron porphyrin content and maceral was established. Indeed, the evidence suggests that the iron porphyrins may accumulate in maceral boundary regions. In small-scale experiments no metalloporphyrins were detected in exinite or fusinite macerals isolated from this coal. The results are briefly discussed." @default.
