Volcanic ash in the Lower Cretaceous Chaswood Formation of Nova Scotia: source and implications Geological Survey of Canada Contribution 20100082. Available to Purchase

Georgia Pe-Piper, David J.W. Piper
Published: 26 October 2010
Canadian Journal of Earth Sciences (2010) 47 (11): 1427–1443.
DOI: https://doi.org/10.1139/E10-078
