Melville Island's coastline is gouged with many large inlets and bays, and ranges in elevation from low beaches to 300-metre cliffs. Its interior topography consists of three main sections. The first is a plateau formed by Dundas Peninsula and the two promontories between Barry Bay and Purchase Bay; the second region is a low plain in the northeast, which extends from Marie Bay east to Long Point, and from Sabine Peninsula north of the land between Eldridge Bay and Sherard Bay; and the third section is a folded upland lying between the first two regions.

The 100 million barrel tar sand deposit at Marie Bay (Trettin and Hills, 1966) on western Melville Island is held in a possible stratigraphic trap in the Bjorne Formation where conventional oil has been highly degraded by exposure at surface.
