Abstract	:	This dissertation presents a suite of geochemical analyses that were conducted to understand petroleum source rocks and hydrocarbon generation. Chapter 2 focuses on detailed geochemical analyses to assess the depositional environment and examine the maturity variations in the Pennsylvanian Turner Mine shale. Subsequent chapters employ experimental approaches to evaluate hydrocarbon generation and associated reaction mechanisms under varying conditions, as well as to assess stable carbon and sulfur isotopes of produced volatiles and solid residues. In Chapter 3, stable carbon isotopes of methane (δ13CCH4) and carbon dioxide (δ13CCO2) were used to assess gas origin and predict hydrocarbon accumulation. A series of hydrous pyrolysis experiments were conducted using immature siliciclastic and carbonate rocks from the Illinois Basin. For comparison, parallel experiments were performed on the rock units over periods of several days at temperatures up to 320 °C and for periods of 14 months at temperatures up to 130 °C. Some experiments were augmented with elemental sulfur (ES) in order to assess the role of variable sulfur valence on yield and carbon isotopic composition of produced CH4 and CO2. In Chapter 4, Raman spectroscopy analyses were conducted to assess the generated gas-phase reaction products from the experiments. Changes in the stable sulfur isotopes of different sulfur species in source rocks can be used to understand the variations in geological, geochemical, and biological factors throughout time. In Chapter 5, we conducted a series of hydrous pyrolysis and heating experiments at 130 to 320 °C, over 3 days to 14 months to assess the extent of thermal sulfate reduction (TSR) and understand the reaction mechanisms for producing different sulfur species. ES with a known isotopic composition was added to a number of experiments to examine the role of ES on reaction pathways and the isotopic compositions of different sulfur species.
