If you're wondering about mountains that existed in Germany millions of years ago, the Triassic sequence of the Iberian Mountain Range consists of the three classical lithofacies typical of the German Triassic: a lower siliciclastic series (Buntsandstein), a middle carbonate and evaporite series (Muschelkalk), and an upper evaporite-rich series (Keuper).
