Excerpt from The Thermal Decomposition of Oil Shales: Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty, of Pure Science, Columbia University Inspissated petroleum - Little is known as to the origin or nature of kerogen or other organic material in the shale. That all of the organic or carbonaceous matter does not produce oil is known.7 E. H. Cunningham-craig attributes the origin of kerogen to inspissated or dried-up petroleum. He concludes that the oil shale stratum is a former oil-bearing formation which, under the action of heat, has evaporated and dried -up, leaving petroleum residues which have become insoluble by polymerization.4 Other authorities are not inclined to accept this theory, as they see no substantial evidence of petroleum having passed through the formation.
