Principles of chemostratigraphic characterization and correlation employing whole-rock inorganic chemical data and heavy mineral grain counts are applied to the frontier Bowser and Sustut basins. Methodologies commonly used with well samples in mature petroleum provinces can be applied to field samples, providing a vital and practical link between the earliest frontier investigations and more advanced hydrocarbon exploration.The major stratigraphic divisions of the basins, the Bowser Lake and Sustut groups, have markedly different indications of sedimentary provenance from heavy mineral analysis, and are readily differentiated geochemically. Variations in key elements are related directly to the provenance indications identified by heavy minerals.
