... Ragazza near Bologna and Castelluccio di Moscheda near Modena, Italy. The X-ray powder patterns indicated a hexagonal cell (more probably rhombohedral in actuality) with a = 3.07 and c = 23.3 Å. Nickel was the dominant cation, and small but consistent amounts of Co and Fe were present. The S content...
