Summary
[edit]DescriptionBonanza Operations, American Gilsonite Company (Bonanza, Utah, USA) 1.jpg |
English: Gilsonite (a.k.a. uintaite) is a variety of asphaltite - it's a solid hydrocarbon - basically solidified oil. Gilsonite usually has the appearance of obsidian or anthracite coal. It 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. Gilsonite occurs there as vertical NW-SE trending 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).
Gilsonite is not readily combustible and is not a fuel, but it does have economic value. Gilsonite is mined in Utah and processed and is used in numerous products and applications (e.g., see: www.geospectra.net/kite/gilsonite/gilson.htm). Locality: gilsonite mining operation at the town of Bonanza, eastern Uintah County, northeastern Utah, USA |
