Eulysite

A rock subtype
This page is currently not sponsored. Click here to sponsor this page.
A high grade metamorphic rock (skarn or meta-ironstone?) consisting of iron and manganese-rich silicates, such as pyroxenes hedenbergite, diopside and ferrosilite, olivine group minerals fayalite, garnet group minerals almandine and spessartine, and amphiboles (hornblende, grunerite and anthophyllite), with accessory apatite, iron oxides, biotite and quartz.

Apparently also described as a variety of peridotite composed essentially of olivine, diopside, opaques and anthophyllite (Le Maitre, 2002).
