I can't speak to the whole issue but the snippet mentions the Missouri earthquakes and diamonds in Arkansas. I know there are plenty of volcanic/contact metamorphic indications in western North Carolina too.

All those indicate substantial tectonic activity: plate movement and some event that allowed plutonic rocks in the form of diatremes (Arkansas) and pegmatite dikes (N.C.) to surge upward from very deep levels. Sounds to me like there was lots of rockin' and rollin' in that area long before Elvis's time.

North America, South America and Africa all mixing it up must have made for exciting times!
