Jeffersonite

Jeffersonite

Jeffersonite is a dark green pyroxene mineral, a manganese zinc enriched variety of augite (Ca(Mn,Zn,Fe)Si2O6), sometimes compared to aegirine. Jeffersonite is not a recognized mineral name.

It occurs in pegmatites where it can form crystals up to 30 cm long and in the contact metamorphic zone between limestone and various intrusive rocks. It is reported from the Sterling Hill mine, Franklin, New Jersey, in South Australia and Sweden.
