Fontarnauite is a relatively recently described, rare borate mineral with the formula (Na,K)2(Sr,Ca)(SO4)[B5O8(OH)]·2H2O. It is found in an evaporate boron deposit. It coexists with other evaporate boron minerals, especially probertite. It is monoclinic, crystallizing in the space group P21/c.[1][2]

It was named in honour of Ramon Fontarnau i Griera, a materials scientist of the University of Barcelona.[2]
