Volcanic ash and lignite of the Lower Cretaceous Chaswood Formation, central Nova Scotia [electronic resource] / G. Pe-Piper, A. Okwese, D.J.W. Piper. Dartmouth, N.S. : Natural Resources Canada, Geological Survey of Canada, 2006. 237 p. : tables, figs., graphs. Open file (Geological Survey of Canada) 5080 "Geological Survey of Canada project GK 4550." Includes bibliographical references. This Open File Report presents stratigraphic, geochemical and petrographic data and a preliminary interpretation of the lignites of the Lower Cretaceous Chaswood Formation in central Nova Scotia, with an emphasis on the recognition of volcanic ash horizons. This study allows estimates to be made of the importance of labile volcanic ash in the correlative offshore sediments of the Missisauga and Logan Canyon formations of the Scotian basin, which are the principal reservoir rocks for the gas resources of the Sable sub-basin. gccst Petrology gccst Stratigraphy gccst Geochemistry gccst Sedimentology Lignite Volcanic ash Petrography Okwese, A.
