They constitute a "Tar sands" first appears in any form in this literature in reference to western Canadian petroleum in an 1891 Annual Report by the Geological Survey of Canada Big Oil is spending millions of dollars to greenwash the tar sands, Canada's fastest growing source of greenhouse gas pollution. It's time for a reality check. 26 Apr 2014 People living near a site of heavy oil production in Canada's tar sands region have been reporting ill health effects, which they believe are
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 Oil sands are a mixture of roughly 90 percent clay, sand and water, with 10 percent bitumen [source: Grist]. The dark, sticky sands look similar to topsoil, are viscous when warm and freeze as solid as concrete in cold temperatures. But calling them "tar" pits or "tar" sands is misleading -- the thick black substance isn't tar, but rather bitumen. Bitumen is composed of a mixture of hydrocarbons. Tar sand, also called bituminous sand, deposit of loose sand or partially consolidated sandstone that is saturated with highly viscous bitumen. Oil recovered from tar sands is commonly referred to as synthetic crude and is a potentially significant form of fossil fuel. A brief treatment of tar sands follows. Oil sands, or tar sands, are sand and rock material which contains crude bitumen, a dense, viscous form of crude oil. Bitumen is too thick to flow on its own, so extraction methods are necessary.

Canada's bitumen giants say their crude has become less carbon-intensive than the average. How do their The Alberta tar sands are one of the biggest oil reserves in the world. Yet extracting the fossil fuel costs more than the profits it's fetching. 15 Apr 2019 Indigenous people and environmentalists want to prevent the expansion of Canada's oil sands development, and the water and air pollution The expression 'tar sands' is a colloquial term used to describe sands that are perhaps more accurately described as bituminous sands.
