Fieldwork conducted by the Bureau of Mines as part of the mineral resource evaluation program of the Yukon-Tanana uplands and vicinity has delineated a northeasterly trend of evaporite deposits within the Yukon Flats Basin. The deposits occur locally as efflorescent salt films less than 1 cm deep about lake margins and dry lake beds within an area of approximately 240 km. The evaporites are precipitated from turbid lakes, which are in contrast with clear lakes elsewhere in the flats. The mineral trona has been identified by x-ray diffraction techniques in major amounts in the evaporites from numerous locations. Calcite and/or dolomite are ubiquitous associates. Trona has also been identified in minor amounts within some lake sediments to a depth of 76 cm. X-ray emission spectrometric analysis has shown sodium to be the dominant element in all samples in the water soluble extract.
