Cl-rich hydroxylellestadite from Zastávka near Brno
At burning mine dumps of abandoned mines at Zastávka near Brno (southern Moravia), Czech Republic, was found mineral from the ellestadite group – Cl-rich hydroxylellestadite. It forms rare pale blue transparent acicular crystals, up to I mm in length, and rich bright blue fine-grained aggregates, up to 1 cm in size, in fragment of burned rock.
