Short summary

Thenardite deposits from the lower Miocene unit of the Tajo basin, Spain, result from a mirabilite diagenetic transformation salt that forms under cool climatic conditions. The time of the mirabilite formation correlates with a Mi cooling event coincident with mammal assemblages related to a relatively cool and arid climate in other basins of the Iberian Peninsula. This diagenetic transformation can be used as an analog with deposits from extreme conditions such as Antarctica or Mars.
