From Drahovzal, J.A., 1997, Proterozoic sequences and their implications for Precambrian and Cambrian geologic evolution of western Kentucky: Evidence from seismic-reflection data: Kentucky Geological Survey, Series XI, Reprint R-44, p. 553-566

Seismic reflection data and interpretation within the western Rough Creek Graben, Crittenden and Caldwell Counties, Kentucky. Sequence contacts shown by white lines. Heavy black lines indicate faults; low-angle lines represent Grenville thrust faults. Dashed, black lines represent reflections in fan complex. Black, right-side-up arrows show locations of reflection onlap. Black, upside-down arrows show locations of reflections representing erosional truncation. White arrows show locations of reflection downlap associated with fan deposits. Examples of Pre-Grenville reflection packages interpreted to be correlative with the volcanic sequence (1) and the Middle Run sequence (2) are shown.
