Summary
[edit]DescriptionGilsonite (Tertiary; near Bonanza, Utah, USA).jpg |
English: Gilsonite (uintaite) from the Tertiary Utah, USA. (FHPR 1328, Utah Field House of Natural History, Vernal, Utah, USA)
Gilsonite has the appearance of obsidian or anthracite coal. Gilsonite (a.k.a. uintaite) is solidified oil. It’s an asphaltite - a naturally solid hydrocarbon - that is jet black in color, very lightweight, brittle, and has a conchoidal fracture. The largest “deposits” of gilsonite in the world are in the Uinta Basin of northeastern Utah, USA. Gilsonite occurs there as vertical NW-SE trending dikes (veins) intruded within the Eocene-aged Uinta Formation. The source of the hydrocarbons is organic-rich beds in the underlying Green River Formation (Eocene) and Wasatch Formation (Paleocene). The dikes were probably emplaced ~10 to 30 million years ago. Gilsonite is not readily combustible and is not a fuel, but it does have economic value. Gilsonite is mined in northeastern Utah and processed and is used in numerous products and applications (e.g., see: www.geospectra.net/kite/gilsonite/gilson.htm). |
