Maybe a geologist can identify these rocks at the base of a cliff? (Campobello Island, New Brunswick Canada)

Continental Drift -- All geologic structures east of the Norumbega Fault, in New England and into Canada, were left behind eons ago when Pangea ripped apart and Europe "drifted" away. And all are remnants of a primordial continent called Avalonia that was crushed out of existence between Eurasia and North America as Pangea initially formed. Thus, eastern New England and coastal Maine share predominant European geology with Cornwall England, The Ardennes, and also the Atlas Mountains of northwest Africa.
