Pirure 1.1 Location and Geologic Map of Western Newfoundland shnriw nmin geologic terranes, areas of stratigraphic study and looales of min W-Zn showings. The distribution of the St. Geame Group is indicated in vertical stripes. Important Pb-zn occurrences include Newfoundland zinc lines, Trapper (T) prospect, Pikes Feeder Pond (A), Eddies Cove East (EC), Cape Noman, Twin Ponds [?PI, Round Pond (UP), sdmn River ISR) and mose Am (a) in the south. A Pb shoving occurs in Silurian carbonates at mrner Ridge (TR) in the White Bay area.
