| Discovery year: | 1938 |
| Operation type: | Underground |
| Deposit type: | Evaporite |
| Production size: | Large |
| Development status: | Producer |
| First production started: | 1962 |
| Host rock: | Green River, Wilkins Peak Member: Trona And Evaporite Bearing Strata |
| Host type: | Evaporite |
| Structure: | Basin And Range Province; Green River Basin; East Of Overthrust Belt, South Of Wind River Mts., Rock Springs Uplift, East Of Trona Area, Stratigraphic High During Much Of Green River Fm. Depositional Period. It Created A Barrier Restricting Water Circulation And Aiding Evaporite Precipitation. |
| Alteration processes: | Trona May Be In Part A Diagenetic Product Of Reaction Between Evaporite Minerals And Na-Rich Water From The Weathering Of Andesitic Tuffs Of Green River Formation. Geochemical Studies (Parker, Et Al, 1971) Have Shown That The Green River Was Probably A Source Of Na-Rich Water. Solution Activity And Reorganization Of Material Is Evident Including Enlarged Grainsize And Secondary Redeposition Of Trona (Parker, Et Al, 1971). |
