Battle Formation
The Battle Formation is a geologic formation of Late Cretaceous (Maastrichtian) age in the Western Canada Sedimentary Basin. It is present throughout much of the central Alberta plains, where it is an important stratigraphic marker in the nonmarine Upper Cretaceous sequence.〔Hathway, B. 2011. Late Maastrichtians paleovalley systems in west-central Alberta: Mapping the Battle Formation in the subsurface. Bulletin of Canadian Petroleum Geology, vol. 59, no. 3, p. 195-206.〕 It was formally named by G.M. Furnival in 1942〔Furnival, G.M. 1942. Cypress Lake, Saskatchewan. Geological Survey of Canada, Paper 42-5〕 and given formation status by E.J.W. Irish in 1970.〔Irish, E.J.W. 1970. The Edmonton Group of south-central Alberta. Bulletin of Canadian Petroleum Geology, vol. 18, p. 125-155.〕〔Glass, D.J. (editor) 1997.
