Stratigraphy of eastern Bay of Exploits, Newfoundland
Fossils from the Fanners Island Formation (new name) show that, southwest of New World Island, Newfoundland, a thick (over 3 km) sequence of late Llandeilo turbidites and basalts overlies the Dunnage mélange. These are overlain by a thicker (6 km) sequence of turbidites, conglomerates, and associate...
