AbstractAlong the southwest arm of Grand Lake a gneiss camp/ex of presumed Grenville affinity con­tains a marble-quartzite unit and is cross-cut by a mafic dyke swarm. Overlying metasedimentary caver rocks, presumed correlative ta the Fleur de Lys Supergroup, contain a camp/ex metacon­glomerate, variable in composition and structural style, which is interpreted as a local/y developed basal deposit. East-over-west Paleozoic ductile shearing, accompanied and overlapped by greenschist ta amphibolite-grade metamorphism, retrogressed the gneiss camp/ex and decoupled basement and caver. This sector of the Steel Mountain terrane is allochthonous, thrust northwest over the Humber Platform sub-zone from an original site east of the Long Range fault, and telescoped into a stack of at least three thrust slices.
