Organic petrology and rock-eval studies on oil shales from the Lower Carboniferous Rocky Brook Formation, Western Newfloundland
journal article Nine samples of oil shale from the Carboniferous Rocky Brook Formation along Rocky Brook in western Newfoundland were studied by incident light microscopy and geochemical analysis (Rock-Eval pyrolysis) to determine the maceral components, geochemical type, and maturation level of the...
