Evidence for photic zone euxinia through the end-Permian mass extinction in the Panthalassic Ocean (Peace River Basin, Western Canada)
A combination of sequence stratigraphic and conodont biostratigraphic analyses of sediment cores from five petroleum exploration wells, together with reference to nearby outcrops, has allowed us to construct a composite geological section through the Permian-Triassic transition in the Peace River Ba...

A combination of sequence stratigraphic and conodont biostratigraphic analyses of sediment cores from five petroleum exploration wells, together with reference to nearby outcrops, has allowed us to construct a composite geological section through the Permian-Triassic transition in the Peace River Basin of Western Canada.
