Abstract

The geology beneath central Lake Michigan is interpreted from a synthesis of 1,700 km of continuous seismic reflection profile data, bathymetry, grab samples, and onshore surface and subsurface information. The map of unconsolidated sediment (primarily Pleistocene) shows thicknesses ranging from 180 m in a steep- walled, northeast-trending valley to less than 10 m over a mid-lake topographic high. These are the dominant features developed on the gently eastward-dipping Paleozoic rocks along this part of the western flank of the Michigan basin. Two structural-stratigraphic cross sections of the study area were constructed. The cross sections, grab samples and other information were used to construct a Paleozoic geologic map. Speculations are made about the petroleum potential beneath Lake Michigan. -from Authors
