Abstract

Compression associated with the formation of the Transcontinental Arch and the Acadian Mountains initiated subsidence in the Michigan Basin and lead to a depositional switch in the Michigan Basin from an oxic shallow-water carbonate platform (Traverse Group and Squaw Bay Limestone) to a deep anaerobic sea floor and the beginning of Upper Devonian Antrim Shale. The vertical distribution of the different Upper Devonian-Lower Mississippian formations and members demonstrates large scale cycles of anaerobic-dysaerobic transitions attributed fluctuations in sea-level, different rates of subsidence and sediment influx triggered by different orogenic events to.

The regional understanding and the distribution of the different lithologies is still poorly understood. This work expands on the mapping of the regional deposits of Upper Devonian-Lower Mississippian by incorporating modern logs and high resolution chemostratigraphic data. New stratigraphic relationships suggest the Ellsworth Shale expanded much further east than previously suggested and the Bedford-Berea sequence postdates the Ellsworth Shale eliminating any possibilities of inter-tonguing. In addition to the expansion of the regional framework, special consideration is given to the Ellsworth Shale petroleum system.
