The Meguma terrane of Nova Scotia, Canada - an aid in trans- Atlantic correlation.

Abstract

The Meguma terrane was the last of the suspect terranes of the N Appalachians to be accreted, becoming linked in the Carboniferous, and therefore holds the greatest promise for tracing its source. The terrane has an extent of up to 200 000 km2 and is composed of thick continental sediment sequences ranging from Late Cambrian to early Devonian, recording the growth of a continental embankment upon a passive margin. Several large modern landmasses are possible sources but NW Africa seems the most likely.-B.W.D.Yardley
