Geologic and geochemical studies of the New Albany Group (Devonian black shale) in Illinois to evaluate its characteristics as a source of hydrocarbons. Quarterly progress report, October 1--December 31, 1977

Results of geologic and geochemical studies of the New Albany Group in Illinois are presented. Information is included on the lithology, stratigraphy, and structure of the New Albany Group. Work directed at characterizing the mineralogic and petrographic properties of this Group is summarized along with results of studies on the physical properties of black shales and studies of elements in Eastern U.S. shales.

Geologic and geochemical studies of the New Albany Group (Devonian black shale) in Illinois to evaluate its characteristics as a source of hydrocarbons. Quarterly progress report, July 1-September 30, 1979

This project is a detailed analysis of the lithology, stratigraphy, and structure of the New Albany Group in Illinois to determine those characteristics of lithology, thickness, regional distribution, vertical and lateral variability, and deformation that are most relevant to the occurrence of hydrocarbons

Geologic and geochemical studies of the New Albany Shale Group (Devonian-Mississippian) in Illinois. Final report

The Illinois State Geological Survey is conducting geological and geochemical investigations to evaluate the potential of New Albany Group shales as a source of hydrocarbons, particularly natural gas. Geological studies include stratigraphy and structure, mineralogic and petrographic characterization; analyses of physical properties; and development of a computer-based resources evaluation system. Geochemical studies include organic carbon content and trace elements; hydrocarbon content and composition; and adsorption/desorption studies of gas through shales. Separate abstracts have been prepared for each task reported

Geologic and geochemical studies of the New Albany Group (Devonian black shale) in Illinois to evaluate its characteristics as a source of hydrocarbons. Quarterly progress report, October 1-December 31, 1979

This project is a detailed analysis of the lithology, stratigraphy, and structure of the New Albany Group in Illinois to determine those characteristics of lithology, thickness, regional distribution, vertical and lateral variability, and deformation that are most relevant to the occurrence of hydrocarbons. Research is reported for this quarter in the following areas: coordination of stratigraphic maps, mineralogic and petrographic characterization, physical properties of Devonian black shale, quantitative determination of major, minor, and trace elements in shales, inorganic/organic associations of trace elements in black shales, mode of occurrence and relative distribution of hydrocarbon phases in shale, and adsorption/desorption studies of gases through shales. 6 figures, 7 tables.
