The continental shelf offshore Nova Scotia is within a passive margin setting and is an excellent area to study the sequence stratigraphy of late Cretaceous and Tertiary sediments. Hydrocarbon exploration offshore Nova Scotia over the past twenty years has produced a substantial amount of well log data. This study integrates the well log data with seismic and biostratigraphic data to create a sequence stratigraphic framework of late Cretaceouse to middle Miocene strata. Sigma Exploration of Calgary has donated access to a large grid of 2D seismic data, covering the outer modern shelf. To help constrain the ages of the sequences, a biostratigraphic analysis of the well Marmora C-34 was performed. Twelve sequences from Campanian to middle Miocene are resolved by integrating the data. Global correlation of results suggest that eustasy is the primary factor in the formation of sequences within the Scotian Basin between lower Eocene and middle Miocene sediments.
