FORMAL DEFINITION OF THE LOWER JURASSIC MCCOY BROOK FORMATION, FUNDY RIFT BASIN, EASTERN CANADA

The name McCoy Brook Formation, presently in informal use, is formally proposed to designate outcrops of Lower Jurassic (Hettangian-Pliensba chian) strata overlying the North Mountain Basalt in the structural Mi nes Subbasin of the Fundy Rift Basin. It is also proposed that this de signation be extended to include stratigraphically equivalent strata b eneath the Bay of Fundy throughout the entire Fundy Rift Basin. It is further recommended that use of the name Scots Bay Formation, the curr ent designation for post-basalt Jurassic sediments outcropping on the south side of the Minas Subbasin, be discontinued. The name Scots Bay Member of the McCoy Brook Formation is used here to designate distinct ive lacustrine strata at the base of the McCoy Brook Formation outcrop ping on both sides of the Mines Subbasin.
