Contact metamorphism of coals in the Southern Piceance Basin, USA: Volatile matter generation, pyrolytic carbon accumulation, and δ13C trends

Four transects of coal were studied to determine petrographic, geochemical, and δ13C changes due to contact with thin sills. Approaching the sills, vitrinite and coke reflectance increases from ∼0.75% to ∼7%, while volatile matter (VM) and H/C decrease. Despite extensive VM loss, the coals do not fo...
