The origin of light hydrocarbons
Webb6 sep. 2000 · There can be little doubt that light hydrocarbons (C 1 –C 9) can be produced thermally from decomposing hydrocarbons in sedimentary rocks.[] Although other pathways have always seemed possible (e.g., catalysis[4, 5]), they were rarely given serious consideration until it became clear that (a) ordinary hydrocarbons should remain stable … WebbSource and migration of light hydrocarbons indicated by carbon isotopic ratios Full Record Related Research Abstract Carbon isotopic ratios can distinguish among different sources of methane and can be used to correlate maturity of sediments with the methane.
