Geochemistry of sulphur in petroleum systems

A renaissance in the 1980s concerning geochemistry of sulfur in fossil fuels makes an update of the subject timely. Papers developed from the 1989 ACS Symposium in Dallas provide a cross-section of recent research and progress in our understanding of the abundance and nature of organically bound sulfur in fossil fuels. This chapter furnishes an overview of our understanding of sulfur introduction into the geologic systems and biogenic materials that produce petroleum and natural gas. Many of the geochemical considerations also apply to coal and lignite deposits. A brief historical account leads to a summary of the most recent advances, an appraisal of current understanding, and some remaining challenges and opportunities for further research.
