Postglacial stratigraphy and sea-level change in southwestern New Brunswick
Cores from small basins in southwestern New Brunswick, above present sea level but below the former marine limit, were examined for microfaunal changes indicating a transition from marine to freshwater conditions. Carbon 14 dates of those transition points add to and strengthen a previous sea-level...
