OUMNH Number: 606  
Name and quarry location: Serpentine, possibly Sterzinger Serpentin, from Vipiteno (Sterzing), Bolzano, Trentino-Alto Adige, Italy  
Geological description: Strongly-foliated meta-ultrabasic rock, green domains appear to be finely-recrystallised tremolite/actinolite. Large pinkish-brown augen-shaped grains may be orthopyroxene, altered to varying degrees. Pyrite and chromite/magnetite are abundant.  
Comments: Comparison with samples in the Naturhistorisches Museum Wien indicates this is almost certainly the serpentinised amphibole-rich rock obtained from Vipiteno (Sterzing) a village in the South Tyrol close to the Italian border with Austria.  
References: Other examples: T2-6-2 C5240 and C5389 'Amphibolserpentin' from Wiesen bei Sterzing, Tirol, and other samples from Sterzing in the Naturhistorisches Museum Wien.
