The Eastport Formation (Lower Devonian) in the northern Passamaquoddy Bay area, southwest New Brunswick

Abstract

Previous interpretations of the stratigraphic position of a series of volcanic and sedimentary strata along the northern coast of Passamaquoddy Bay, New Brunswick, are somewhat enigmatic. Recent fieldwork has indicated that the sequence is a lithostratigraphic, biostratigraphic, and most probably a chronostratigraphic equivalent to the Eastport Formation (Gedinnian) of Maine, located a few kilometres to the west. It is proposed that henceforth, the succession be termed the Eastport Formation.
