Elaterite, also known as aeonite, elasticite, elastic bitumen, or mineral caoutchouc, is a brown, often sticky, hydrocarbon. First discovered at Castleton, Derbyshire, in England, elaterite is not considered to be a mineral species. It has sometimes been confused with coorongite, found in Australia, but it has been determined that the origins of the two substances differ.
The origin of the name elaterite lies in the Greek word ελατηρ, meaning "pine", so named as it was assumed to have formed from the resin in pine trees.[1] It is or has also been known as aeonite, elasticite, elastic bitumen, or mineral caoutchouc.[1]
Description
The substance varies somewhat in consistency, being sometimes soft, elastic and sticky, like India rubber, and occasionally hard and brittle. It is usually dark brown in colour and slightly translucent.[2]
Although coorongite is of a very similar composition to elaterite,[3] it is not the same substance nor of the same origin.[4][5]
Occurrence in nature
Cave and elaterite, Windy Knoll quarry
Castleton, Derbyshire: Elaterite can be found beside the Windy Knoll Cave[6][7] and the lead mines of Odin in Derbyshire, England, UK.[1]
Strawberry, Utah, US: Elaterite can be found in the Indian Canyon, Sams Canyon, Dry Fork, and Lake canyon, as well as in tributaries of the Strawberry River in Duchesne County. It occurs in vertical veins 1–22in (25–559mm) wide, 2–200ft (0.61–60.96m) high, and a maximum length of 3.25mi (5.23km).[8]
