Chalcopyrite & Galena

Reference: 2947

In the 1980s the old tips of South Llangynog mine were worked through by Pentre quarry. Collectors soon after found blocks of mineralised veinstone in the quarry covered in calcite which on removal exposed some of the best sulphide specimens found in Wales. This specimen from that find shows galena epitaxially overgrown by bright chalcopyrite crystals all dotted over a bed of quartz.  Ex. Jim Padden collection
