OUMNH Number: 964  
Name and quarry location: Corsica, from Corsica, France  
Geological description: Metagabbro. A weakly metamorphosed gabbroic pegmatite, with green diopside (pyroxene) and brighter green aggregates of acicular actinolite-tremolite (amphibole) crystals. Some black grains of an oxide mineral are present.  
Comments: The locality may be correct. A bright green metagabbro from Mont San Pedrone has long been worked for decorative purposes (see no.700) and is known as smaragdite di Corsica or plasma di smeraldo. This sample could be from a peripheral part of that deposit.
