Oil shale bings :: Shared Description

The shale oil bings of central Scotland are noted for their size and colour. The reason for the size is due to two principal factors.
The first is the volume of rock which had to be extracted to produce a given amount of oil. Typically shales contain about 12 to 25% volatile content, so between 75% and 88% is waste.
The second is that the extraction process lends itself to being concentrated in large scale works, rather than being carried out at individual mines, so a single bing represents the output of several mines. The nature of the substance meant that little waste would be tipped at the pit head. The oil, principally ending up as paraffin or similar products, is extracted by heating the shale at high temperatures to drive out the volatile hydrocarbons. The high temperatures give the residue its red colour, in the same way that bricks are typically red after firing. The waste is now virtually inert, which has the result that vegetation finds it hard to gain a foothold.
It is noticeable that older bings where the extraction process was perhaps less efficient tend to have more growth.

These Shared Descriptions are common to multiple images. For example, you can create a generic description for an object shown in a photo, and reuse the description on all photos of the object. All descriptions are public and shared between contributors, i.e. you can reuse a description created by others, just as they can use yours.
