RM2843   Aerinite in dolerite

Reguer del Congost, Estopanyà (Estopiñán del Castillo), Huesca, Aragón, Spain

Blocky aerinite criptocristalline with fragments of dolerite included. Aerinite was used as a blue pigment in many Romanesque paintings in the Pyrenees between the 11th and 14th centuries. Its characteristic blue color varies from dark to pale blue. In fact, its name comes from a Greek root aerinos meaning "atmosphere" or "sky", as it was only known by that color.
