| Summary: | This paper examines the occurrence of white evaporitic deposits on Antarctic meteorites from the U.S. collection, as a function of meteorite compositional group and weathering category. Evaporites occur with unusual frequency on carbonaceous chondrites. Almost two-thirds of all evaporite-bearing meteorites belong to weathering categories A, A/B, and B. Where chemical data were available, surficial evaporite deposits could be associated with elemental anomalies in meteorite interiors. |
