THE JOGGINS AND SPRINGHILL MINES FORMATIONS FACIES MODEL AND INTERPRETATION OF THE PALED-ENVIRONMENT
(1998-04-15)The type section of the Joggins Formation is located along the eastern shore of Chignecto Bay, Nova Scotia. A bed-by-bed measurement of the Carboniferous strata within a 200m stratigraphic zone encompassing the Joggins ... -
Lacustrine Cyclic Sedimentation in the Lower Carboniferous Horton Bluff Formation at Rainy Cove, Nova Scotia
(1987-04-15)The Lower Carboniferous Horton Bluff Formation at Rainy Cove in Nova Scotia is an excellent coastal cliff exposure of lacustrine strata. The freshwater depositional conditions are inferred from the presence in the strata ... -
