The San Salvatore Dolomite, sometimes known as the San Salvatore Formation, is a Middle Triassic (late Anisian) geological formation in Switzerland and Italy. The primarily lithology is micritic dolomite with a high proportion of algal mounds (stromatolites).[1] It corresponds to a thick warm-water carbonate platform on the northern edge of an island in what is now the Po Plain. This formation and its local equivalents are common in the hills around Lake Maggiore, Varese, and Lugano, preserving fossils of marine invertebrates such as ammonoids, gastropods, and bivalves. At its western extent, the San Salvatore Dolomite is overlain by black shales of the Besano Formation, which was deposited in a deeper and more anoxic lagoon.[2][3][4]
