Basement and Structural Control of Ordovician Trenton Dolomite in Extreme Southeastern Michigan, with Emphasis on Hydrocarbon Accumulations in Relationship to Dolomitization Available to Purchase

Recent exploration activities along the northerly extension of the Bowling Green fault have sparked renewed interest on the flanks of one of North America’s first giant oil fields (Lima-Findlay field). Extreme southeastern Michigan lies on the northwest flank of the Cincinnati arch and the southeastern flank of the Michigan basin. Within the study area, basement and structural control dictate the occurrence of dolomite within the predominantly limestone Trenton Formation. Commercially productive hydrocarbon accumulation within this study area has been associated with dolomitization within the top 150 ft (46m) of the Trenton Formation.
