This volume investigates the chemical processes and organic matter transformations occurring within geological environments as presented at the 1968 International Meeting on Organic Geochemistry. The editor, P.A. Schenck, compiles a series of technical papers that examine the distribution, origin, and migration of organic compounds in sedimentary rocks and petroleum systems. The work serves as a record of the state of geochemical research during the late 1960s, utilizing analytical chemistry methods to interpret geological phenomena.

Experts recognize this volume as a historical record of the foundational methodologies used in organic geochemistry during the mid-20th century. Readers frequently note the high academic density of the prose and the specialized nature of the technical reports included.
