Green sphalerite was found in quartz and calcite veins at Jones Mill Quarry. It is not rare, but tends to be locally abundant. While assumed to be sphalerite based on physcial properties, is was not analysed. This sample is a group of clear green crystals etched from a calcite-anatase vein and shows only Zn and S peaks. The red spectrum has background subtracted and the purple spectrum is the raw data.
