467.3 - 485.4 Ma
Age: Ordovician (467.3 - 485.4 Ma)
Stratigraphic Name: Moretown Formation
Comments: Part of Rowe-Hawley Zone (Ordovician and Older Rocks). Early Ordovician age from zircons (479+/-8 Ma) constrains the age of the previously undated Moretown Formation to Early Ordovician or older. Moretown had been interpreted as Middle Ordovician based on correlations with the Beauceville Formation of southern Quebec and the Missisquoi Formation of VT (Karabinos and Williamson, 1994) per MA005.
