Log correlation of Cambrian of Michigan basin
Log correlations are presented for the lower peninsula of Michigan and for adjoining parts of Indiana, Ohio, and Canada. Isopach maps were constructed for the Mount Simon, Eau Claire, Galesville, Franconia, and Trempealeau formations. Two depocenters were present during the Mount Simon - one just west of Saginaw Bay and another in northeastern Illinois, the margin of which extends into southwestern Michigan. The Eau Claire isopach map indicates a relatively stable Michigan basin with the Eau Claire thickening southwest into Illinois. Stability continued during the deposition of the Galesville Sandstone, which entered the basin from the west from a source in the Wisconsin highlands. Relatively strong subsidence resumed in the Saginaw Bay depocenter during the accumulation of the Franconia Formation. The Trempealeau Formation records only a slight increase at this depocenter, but thickens markedly to the south into Indiana.
