註釋

"This report... deals primarily with a rock sequence of Middle Silurian to Middle Devonian age that is transitional between shelf carbonates in the northeastern part of the Virginia Falls map area (NTS 95F) and basinal shales of the Road River Formation farther south and west... These transition facies were deposited in the Root Basin and a paleo-depression herein named the Prairie Creek embayment. This embayment, which is characterized by subtidal slope deposits, occurs in the north-central part of the Virginia Falls map area and is bounded on the east, north, and west by shelf carbonates. Carbonates on the west side were deposited on a shallow water shelf salient named the Sombre Salient. Southward and southwestward, the transitional units become increasingly shaly and lose their identities in the deep water Road River Formation in the southwestern part of the map area." --Introd.
