Abstract: Bowling Green Fault--Case of Resurgent Tectonics?

R. C. Quick, E. F. Pawlowicz, W. J. Hinze

The Bowling Green fault lies along the west flank of the Findlay arch and is a part of the Lucas-Monroe monocline. Detailed gravity and magnetic studies in Wood and Lucas Counties of northwestern Ohio indicate that the trend of the fault parallels the west flank of a strong north-south-trending gravity and magnetic high, interpreted to represent an abrupt change in the character and structure of the basement rocks. This geophysically defined boundary in the basement can be traced northward across parts of southeastern Michigan and Lake Huron to the vicinity of exposures of the Grenville front in Ontario, and southward across Ohio. The correlation of this boundary with some Paleozoic structures that flank the Michigan basin is strong evidence that the boundary had been a z ne of basement weakness which was reactivated during the formation of the Michigan basin. The association of petroleum accumulations with geophysical trends, such as the Albion-Pulaski-Scipio trend and the Lucas-Monroe monocline, illustrates the economic potential of detailed gravity and magnetic data in structural and tectonic interpretations.
