Post-Eocene fault near east edge of Reelfoot Rift in Lauderdale County, Tennessee, as discovered by gravity, earth resistivity surveys, and drilling

Technical Report ·
OSTI ID:5414210
A search for faults was made along the east edge of Reelfoot Rift using techniques proved at Reelfoot Scarp. Gravity was the larger area screening device. Narrow elongated residual anomalies could mark faults, but whether faults extend to the surface would be unknown. Earth resistivity profiling was used to search for abrupt near-surface lateral changes in electrical conductivity which could indicate a fault within about 200 feet of the land surface. This technique led to a precisely located fault about 5 miles east of Henning in Lauderdale County, Tennessee. Drilling verified the fault location, and offset sense (downthrown on the east side). The throw of the fault was estimated to be roughly 100 feet or more from earth resistivity profiles, but drilling indicated only about 40-70 feet of offset.
