Structural geology of the Moorman syncline area of western Kentucky
Abstract
The structural development of the Moorman syncline through time is traced. A background for a remote sensing study of that area from LANDSAT images is sought. Topics covered include the geologic history of the area and a structural analysis of five major fault zones: the southern Illinois rift, the Wabash fault zone, faults of the Mississippi embayment, the Rough Creek fault zone, and faults of the southern shelf. The importance of Precambrian structural trends and Cambrian rift zones in the basement is emphasized. Surface structures are illustrated from published maps and sections, which show a variety of styles from simple extentional normal faults to complex shear zones associated with wrench fault tectonics. Growth movement throughout the Palezoic is an important aspect of the structural development of the area, but the surface structures primarily result from intense deformation during a late Paleozoic deformation and subsequent Mesozoic deformation that emanated from the Mississippi embayment. The distribution of reported earthquakes indicates that the crust within the area is still active.
