| Description/Abstract | Devonian strata in the Michigan Basin are represented by variably thick sequences of open shelf, tidal flat and sabhka carbonates, interbedded with basin-centered and sabhka evaporites (anhydrite and halite).^Although there are isolated outcrops around the margins of the basin, the lithofacies relationships of these strata can be best studied from subsurface data of cores, wireline logs, and drill cutting samples.^This database is compiled from over 25,000 oil and gas wells that enter or entirely penetrate Devonian strata in Michigan.^Most of the strata in the Michigan Basin Devonian are part of the Kaskaskia cratonic depositional sequence (Sloss, 1963).^The sequence begins with the southeast to northwest transgression of a quartz arenite (Sylvania Ss.) sandstone facies onto a weathered, cherty carbonate (Bois Blanc Fm.) surface developed on Lower Devonian strata exposed during the post-Tippecanoe unconformity.^With rising sea level, the basin sediments became dominated by open shelf, biohermal and locally restricted lagoon carbonates (Amherstberg Fm.).^Much of the Middle Devonian is represented by thick basin-centered sabhka and salina evaporates and restricted-environment carbonates (Lucas Fm.).^These interbedded and laterally gradational evaporite/carbonate facies are cyclic, showing gradual salinity changes during accumulation.^Stratigraphically important K-Bentonite marker beds are prevalent in this part of the Michigan section.^Overlying this restricted sequence are again open shelf, biohermal, and local restricted sabhka carbonate deposits (Dundee Fm.).^Thin, but widespread and eastwardly thickening, terrigenous shales and mudstones are intercalated within another shelf carbonate package (Traverse Group).^Devonian deposits in the Michigan Basin are capped by thick black shales and interbedded carbonates (Antrim Fm.). |
