Oil sands, including the Athabasca Oil Sands in northern Alberta, are the second largest hydrocarbon resource on earth. In the last decade, engineering technology has evolved that can now economically produce the bitumen resource in the oil sands. This volume showcases the geology of oil sands from around the world. It highlights the Athabasca Oil sands of northern Alberta and the geochemistry of the associated bitumen resource, but points directionally toward the development of other oil-sand deposits in the world. A novel feature is the ‘case study’ approach. Although much of the perspective is sedimentological and/or stratigraphic, the substance of the book should fine wide appeal to Earth scientists working in all geoscience domains.
