Description

The name Granville Basin was applied to an irregularly lobed depression located just west of La Salle Anticlinorium. The basin was identified from subsurface mapping of various Cambrian and Ordovician horizons. It was mapped as having closure of about 50 feet (15 m). Several other structural ridges and troughs, named as anticlines and synclines, were shown as radiating from the Granville Basin.

No evidence for an enclosed depression in this area appears on the structure map of the Galena (Trenton) Group (Bristol and Bushbach 1973) or the map of the Franconia Formation (Cambrian; Kolata et al. 1983). The use of the name Granville Basin should be discontinued.
