oremin: Single prismatic amphibole crystals are occasionally encountered with fibrous blue terminations resembling paint brushes or are totally covered with fibrous blue needles oriented parallel to the c-axis. According to analyses of the composite crystals, composition ranges from fluorine-rich riebeckite at the fibrous termination to ferrorichterite, then to riebeckite, ferrowinchite, ferrorichterite, and finally to katophorite at the base of the prism"" (Becker, 1991, p. 457).
