Abstract

Salina salt deposits in the center of the Michigan basin are characterized by annual layering and clear and cloudy salt alternations, suggestive of deep-water deposition. Basin-margin salt contains features such as minor unconformities, recrystallized patches, and ripple marks. In the Appalachian basin, a turbulent shallow-water environment is suggested by destruction of salt layering, presence of crossbedding, transported shale balls, and available paleoecological information.
