  • What are tar sands? American Geosciences Institute

    2020-7-20  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.

  • Mining in the Boreal - Tar Sands Global Forest Atlas

    2020-6-15  A key area of controversy over mining in the boreal region is the exploitation of tar (or oil) sands, which are areas with sand or sandstone saturated with bitumen, a viscous form of petroleum, which can be mined and processed to produce oil. Tar sands are extracted by either surface (open pit) mining or in-situ extraction. For surface mining, areas are first cleared of trees, bogs are drained ...
