| Synopsis | Five faults in terrace deposits of probable Quaternary age were reported but not named by Bollinger and others (1992 #1800) and Law and others (1992 #1850). Mills (1994 #1864) referred to the faults collectively as "the Pembroke fault". The faulted locality is along the north side of the New River Valley, between Pembroke and Pearisburg, Virginia, approximately 1 km west of Pembroke.
These are probable Quaternary faults that overlie a steeply dipping, tabular zone of hypocenters. However, it has not yet been determined whether the faults are tectonic or the result of solution collapse. |
