The Devonian Antrim Shale is an unconventional biogenic gas accumulation with a technical recoverable resource of 19.9 Tcf. However, major knowledge gaps remain regarding understanding of the source rock potential, organic facies assemblages and paleo-depositional conditions of the Antrim Shale members. This work utilized Rock-Eval pyrolysis, reflected light microscopy and solid bitumen reflectance to characterize the source rock quality, organo-facies assemblages, and thermal maturity of the various Antrim Shale members at three different localities in the Michigan Basin. Results showed that the Lachine and Norwood members are richer in organic matter (up to 24wt%) than the Upper and Paxton members (< 8wt%).  Organic matter in the black shales of the Lachine and Norwood members is mainly dominated by marine Type II kerogen, and Type II and Type II/III in the Paxton Member. Telalginite, which is represented mainly by Tasmanites and Leiosphaeridia cysts, is the dominant organic matter in the black shale members where they account for about two-thirds of the organic matter composition. Solid bitumen, which accounts for less than one-third of the organic matter composition, is second after alginites. Both alginites and solid bitumen populations decline in abundance progressively in the Upper and Paxton members at the expense of inertinite and vitrinite. The dominant organofacies groups in the studied Antrim Shale members can be assigned to the BP type B and type D/E. Organic matter maturity determined from Rock-Eval Tmax and bitumen reflectance varies from immature to marginally mature across the Michigan basin. The results confirmed that sediment burial depth and lateral positions in the basin controlled organic facies assemblages within the Antrim Shale members.


Adedoyin is a PhD student in the Department of Earth and Atmospheric Sciences at Central Michigan University (CMU). He earned his B.S. degree in Geology from Obafemi Awolowo University (Nigeria) and his M.S. degree in Geology from the University of North Dakota (USA). In between his Bachelors and Masters, he worked as a petroleum geologist in Nigeria for 3 and half years where he utilized seismic data, well logs and other subsurface data for prospects evaluation. He is currently working on the petrographic, petrophysical and geochemical studies of the Antrim Shale in the Michigan Basin.

Geology in the News

New Survey Publication – An Updated Bibliography of Michigan Geology

John Yellich and Peter Voice, Western Michigan University Department of Geological Sciences and Michigan Geological Survey

The Michigan Geological Survey is proud to announce a new publication: Michigan Geology: A Bibliography, the second volume in the Michigan Geological Survey Data Compilation Series. This updated compilation lists over 7,700 references from all known Michigan sources, including industry, professional associations and universities and includes publications from 1818 to present. This report documents 200 years of Geological Research in Michigan. The Bibliography is sorted into four general categories – Precambrian, Basin, Quaternary, and Other.
This updated version of the bibliography also includes a short section on Michigan Stratigraphic Nomenclature, as well as brief discussion of historical trends in publication frequency in Michigan.

The report is free to download at the Michigan Geological Survey’s webpage:


Douglass Houghton, Michigan’s first State Geologist, was honored on September 10, 2016 by
the placement of a State of Michigan Historical Marker commemorating his accomplishments. The
effort was led by Arlene Anderson‐Vincent, members of the Michigan Basin Geological Society,
Keweenaw County Historical Society and faculty at Western Michigan University and Michigan
Technological University. The dedication was incorporated into a MBGS field excursion led by
Professor Ted Bornhorst of Michigan Technological University and Lawrence Molloy, President of the Keweenaw County Historical Society. The two led a field excursion that covered the geology and history of sites from Houghton to Copper Harbor and wove a tale of the rise and fall of mining in the copper range. The field excursion included the dedication of the marker, which is located in Eagle River, Michigan at the Keweenaw County Historical Museum. The dedication had many speakers and a special appearance from Kyle Bagnall, who portrayed Bela Hubbard who told the story of Douglass Houghton’s 1840 expedition along Lake Superior. Douglass Houghton died in 1845 when the boat carrying himself and his crew capsized during a storm on Lake Superior near Eagle River.

The Michigan Basin Geological Society (MBGS) was founded in 1936 as an affiliated non-profit organization of the American Association of Petroleum Geologists (AAPG) to provide a forum for the exchange of ideas relating to the field of petroleum geology through field excursions and meetings.

Throughout the years, the role of the society has changed, and both meetings and field excursions now address a wide range of topics pertaining to the study of geology of Michigan and the great lakes area, and is open to anyone interested in geology.

MBGS has monthly meetings typically on the second Wednesday of each month from September through May. These meeting consist of a lecture on a wide variety of Michigan geology related topics. The meetings are open to all. The Executive Committee Officers meet prior to the meeting to discuss Society issues and is open to anyone interested in attending. The society has 1-3 geological field trips per year.

MBGS members are geologists, work in a geology related field, or are a geology student or hobbyist. The Society is dedicated to the advancement of the science of geology and related fields, disseminating knowledge of geology or related fields for the benefit of its members, and promoting the education of geology in Michigan. Annual dues are $35 per person and $10 per student.
