Thenardite after mirabilite deposits as a cool climate indicator in the geological record: lower Miocene of central Spain
Salt deposits are commonly used as indicators of different paleoclimates and sedimentary environments, as well as being geological resources of great economic interest. Ordinarily, the presence of salt deposits is related to warm and arid environmental conditions, but there are salts, like mirabilit...
