New York-Alabama Lineament

The New York-Alabama Lineament is a magnetic anomaly in the geology of eastern North America running from Alabama to New York. The lineament is defined by discontinuities in aeromagnetic measurements indicating an approximately 220-kilometre (140 mi) displacement of buried geologic structures along this line. The displacement is attributed to the presence of a deeply buried strike-slip fault, possibly dating to the general time of the Grenville orogeny. The lineament was first described in 1978.[1] The fault zone has been associated with the Eastern Tennessee Seismic Zone.[2]
