Abstract
Carboniferous Redbeds of Alluvial Origin, Spanish Room Formation, Avalon Zone, Southeastern Newfoundland
ABSTRACT
Carboniferous sedimentary rocks are exposed at Spanish Room Point on the Burin Peninsula, southeastern Newfoundland, where 15.5 m of Tournaisian limestone, shale and minor sandstone, referred to as the Cashel Cove beds (new informal name) and of probable lacustrine origin, were tilted before deposition of the Spanish Room Formation. The latter is an internally conformable redbed sequence consisting of 120 m of alluvial-fan conglomerates, 170 m of floodplain siltstones, crevasse-splay sandstones and caliche horizons, and an 8-m-thick fining-upward point-bar deposit capped by an inferred chute-channel fill. The Spanish Room Formation contains no fossils, but is tentatively assigned a ?Visean - lower Namurian age based on paleoclimatic comparison with other Carboniferous strata in Atlantic Canada. The sequence at Spanish Room Point indicates 1) steep relief and 2) local Early Carboniferous deformation, both consistent with deposition in the strike-slip regime that has been proposed to explain the evolution of Late Paleozoic basins in Atlantic Canada.
