M., Brickles, S. L., Licht, K. J., & Monaghan, G. W. (2017). Exploring the use of zircon geochronology as an indicator of Laurentide Ice Sheet till provenance, Indiana, USA. Quaternary Research, 88(3), 525–536. https://doi.org/10.1017/qua.2017.71 Abstract A pilot study was designed to evaluate the potential of zircon geochronology as a provenance indicator of till from the Lake Michigan, Saginaw, and Huron-Erie Lobes of the Laurentide Ice Sheet. Based on existing ice flow-path models, we hypothesized that till from each lobe would have different zircon age population distributions because the lobes originated from regions of the Canadian Shield with different bedrock ages. After correcting for zircon fertility, the majority of grains in all till samples are 1600–950 Ma, with ~30% of ages >2500 Ma. This similarity means that till from the three lobes cannot be clearly differentiated based on their zircon populations. The dominant ages found and the homogeneity of distributions in the till indicates a non-Shield source and instead reflect an origin from some combination of underlying till and sedimentary bedrock in the Great Lakes region.

  • Pennsylvanian Pewamo Formation and Haybridge Strata of Central Michigan: the Youngest Rocks of the Michigan Basin?
    The Geological Society of America Special Paper 531 Pennsylvanian Pewamo Formation and Haybridge strata of central Michigan: The youngest rocks of the Michigan Basin? Kathleen C. Benison* Department of Geology and Geography, West Virginia University, 98 Beechurst Avenue, Morgantown, West Virginia 26506-6300, USA ABSTRACT Pennsylvanian red beds are the youngest known rocks in the Michigan Basin. Two new formation-level units, the Pewamo Formation and the Haybridge strata, have recently been described. The Pewamo Formation, composed of Pennsylvanian red sandstones and minor laminated mudstones, is known from outcrops, abandoned quarries, and one core in Ionia County. The Haybridge unit is located in the shal- low subsurface and in coal mine tailing piles in Shiawassee County. It consists of red sandstone, red mudstone, coal, and gray mudstone, all hosting Pennsylvanian macroscopic plant fossils. Neither the Pewamo nor the Haybridge rocks have any demonstrated relationship to red core cuttings reported as Jurassic from the central Lower Peninsula of Michigan. No fi rm evidence exists for Jurassic, or any other post- Pennsylvanian rocks in the Michigan Basin. The red core cuttings may be glacial sediments with reworked palynomorphs from rocks transported from elsewhere. A shallow coring project, followed by detailed sedimentologic, petrographic, miner- alogic, and paleontologic studies, is necessary to: (1) refi ne the vertical and lateral stratigraphy of the Pennsylvanian rocks in Michigan; (2) solve the “Jurassic red bed problem”; and (3) understand the late Pennsylvanian–Pleistocene history of the Michigan Basin. INTRODUCTION This time has been referred to as the “missing interval” for the Lower Peninsula of Michigan. The Michigan Basin is rich in geologic resources, including The purpose of this paper is threefold: (1) to provide an over- oil, gas, salt, groundwater, and sand and gravel.

Yochelson (1928-2006), principal organizer of the first NAPC (1969) and a major catalyst in its establishment as a highly successful quadrennial meeting. Welcome On behalf of the Associated North American Paleontological Societies, it is my pleasure to welcome you to Cincinnati for the 9th North American Paleontological Convention (NAPC 2009). As the abstracts in this volume attest, this is a wonderfully eclectic meeting, with sessions and presentations covering an array of taxa, and touching on important questions and themes that drive the science of paleontology in the 21st century. In the year when we commemorate the bicentennial of Charles Darwin’s birth and the sesquicentennial of The Origin of Species, it is appropriate that NAPC 2009 take place in Cincinnati. There are few places on the continent that can match the rich paleontological heritage of this region.
