The Syracuse Formation is a geologic formation in the Appalachian Basin. It is the main salt bearing formation of the Salina Group. This formation depending on location contains up to six salt beds. Aside from salt the formation is made up of dolomite, shale, gypsum and anhydrite. Salt is commercially extracted in Michigan, New York and Ohio. Gypsum mining operations in Michigan and New York are also noted.{{Cite web |last=Rickard |first=Lawrence |date=4 April 2023 |title=Stratigraphy of the Upper Silurian Salina Group New York, Pennsylvania, Ohio, Ontario |url=https://nysm.nysed.gov/sites/default/files/mc12_stratuppersiluriansalinagrpnypaohon.pdf}}
