Abstract:

Fossiliferous Silurian rocks are exposed in several areas from western White Bay to Sir Charles Hamilton Sound, northeastern Newfoundland. This article summarizes the several sequences of sedimentary rocks on New World Island and nearby islands that are recognizably lower Silurian because of their fossils. Thousands of feet of sediments were deposited unconformably on Ordovician sedimentary rocks, lavas, and fragmental volcanic rocks. The conglomerate contains abundant and large volcanic and plutonic boulders, the latter increasing in proportion upward and in size northward. They are thought to have been derived by erosion from fault blocks on the north. The sequences on the east and west are summarized only briefly.
