Geology
Host rockEvaporite · Green River, Wilkins Peak Member: Trona And Evaporite Bearing Strata
StructureRock 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., Basin And Range Province; Green River Basin; East Of Overthrust Belt, South Of Wind River Mts.
AlterationTrona 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).
