What are tar sands? | American Geosciences Institute
Tar sands (also called oil sands) are a mixture of sand, clay, water, and bitumen.[1] Bitumen is a thick, sticky, black oil that can form naturally in a variety of ways, usually when lighter oil is degraded by bacteria.[2] Bitumen has long been used in waterproofing materials for buildings, and is most familiar today as the binding agent in road asphalt.
