Fehrite is a hydroxyl-bearing, hydrated, copper-magnesium sulfate mineral approved by the International Mineralogical Association as a new species in 2019,[1] and formally described in 2021 from specimens obtained from the Casualidad mine, located near Baños de Sierra Alhamilla, in Pechina (Almería), Spain, which is consequently the type locality. The name is a tribute to Karl Thomas Fehr, Professor of Mineralogy at the Ludwig Maximilian University in Munich (Germany).[2]
