In terms of sequence stratigraphy, the succession consists of a basal type 1 sequence (the Meguma Supergroup) and three overlying type 2 sequences (collectively, the Annapolis Supergroup).

...John W.F. Waldron; Chris E. White Abstract The paper “Geochemical signature of Ordovician Mn-rich sedimentary rocks on the Avalonian shelf” (Romer et al., published in 2011) describes six samples of which four are from the Meguma Supergroup of Nova Scotia. Previous work indicates that these samples...

... Mesozoic during the breakup of Pangea when Morocco and what is now Nova Scotia rifted apart. The evolution of the Nova Scotian margin at the start of rifting (Middle Triassic) involved deformation of metasedimentary rocks of the Meguma Supergroup (lower Paleozoic), but deformation continued to at least...

... of considerable debate for several decades, largely because Meguma Group or Supergroup ( Pratt and Waldron 1991 ; Schenk 1995 , 1997 ) in Nova Scotia is a 10,000m thick group of metasediments with very few identifiable fossils. Two deposits (text-fig. 1 ) that came to the attention of the authors, however, were...

As a result, Schenk (1991 , 1995) proposed correlations among these members at specific localities around the western margin of southern Nova Scotia, and in the 1995 paper, proposed elevation of the members to formations, the Goldenville and Halifax formations to groups, and Meguma Group to Supergroup...
