...C. R. van Staal; S. Lin; P. Valverde-Vaquero; G. Dunning; J. Burgess; D. Schofield; N. Joyce The Meelpaeg structure in southwestern Newfoundland comprises allochthonous tectonites formed during the Salinic (D 1-2 ) and Acadian (D 3 ) orogenies. D 1-2 occurred between 451 and 417 Ma and culminated...

... of southwestern Newfoundland is required. The Overfall Brook Member of the Robinsons River Formation, formerly assigned with its correlative, the Brow Pond Lentil, to the Codroy Group, is here identified as a basal unit of the Searston Formation. It lies unconformably on Codroy Group beds of Brigantian age...

... the Margaree orthogneiss, is part of a package of gneissic rocks that crop out in southwestern Newfoundland between the peri-Laurentian rocks of the Dashwoods subzone ( Williams 1995 ), including the Windsor Point Group and the peri-Gondwanan, Exploits subzone equivalent, rocks of the Bay du Nord Group (see...

...Benoît Dubé; Kathleen Lauzière Abstract The Cape Ray Fault Zone is a major Paleozoic structure in southwestern Newfoundland, and occurs at or close to the boundary between two major continental blocks, Laurentia and Avalonia. A detailed structural analysis demonstrates that the fault records early...

...R. Wiseman; Hugh G. Miller Abstract Several Newfoundland Appalachian terranes converge in the southwest corner of the island. The recent Lithoprobe East deep seismic reflection profiles imaged the crust along a transect across this area. In this paper, we present the gravity and magnetic data...

...J. Victor Owen Abstract In southwestern Newfoundland, pelitic migmatites of the Meelpaeg Subzone of the Gander Zone are separated by faults and plutons from metasedimentary rocks of the Port-aux-Basques gneiss complex (PBGC). The PBGC is a polymetamorphic sequence of amphibolite-facies, pelitic...

...K. L. Currie; M.A.J. Piasecki Abstract Southwest Newfoundland consists of a mosaic of subzones or terranes recognized by distinctive lithostratigraphy, plutonism, and metamorphism. Subzone boundaries trending east-west exhibit north-over-south thrusting, but northeast-trending boundaries exhibit...

... of southwestern Newfoundland. Wall rocks to the electrum-bearing quartz veins were subjected to potassic alteration and minor enrichment in chalcophile elements. Ore metals in the showings are Au, Ag, Cu, Pb, and Zn, and their distributions resemble those seen in gold-bearing massive sulfide deposits...

...Derek H. C. Wilton Abstract Four granitoid suites are recognized in the region of the Cape Ray Fault Zone of southwestern Newfoundland. The two oldest (Ordovician–Silurian (?)) suites represent partial melts of their enclosing host rocks. The Port aux Basques granite is modelled as a partial melt...

...P. J. Wynne; David F. Strong Abstract Zones of Fe-Zn-Pb-Cu sulfide mineralization exposed in the Strickland area of southwestern Newfoundland are interpreted to represent diverse portions of one or more volcanogenic massive sulfide deposits which have been subjected to cataclastic deformation...

...Derek H. C. Wilton Abstract Structural studies within the Cape Ray Fault Zone, southwestern Newfoundland indicate that three tectonic events (D1 to D3) have deformed all regional lithologic units. These lithologies are distributed as a tonalitic terrain (intrusive into ophiolitic remnants...

...P. H. von Bitter; H. A. Plint-Geberl Abstract Four stratigraphically successive conodont assemblage zones have been recognized in the Lower Carboniferous Codroy Group of southwestern Newfoundland. The Diplognathodus Zone is confined to the basal Ship Cove Limestone, and to a highly fossiliferous...

...Jens Müller; John D. Milliman Abstract Surface sediments on southwestern Grand Bank are composed mostly of sand, with local admixtures of mud and gravel. Most sediments are enriched with biogenic calcium carbonate, primarily barnacle valves with lesser amounts of mollusk, echinoid, and foraminifera...
