Not that well known for its minerals, but lets see what we receive - calcite and goethite


calcite_pyrite_hfq_3_148.jpg
 Description:
Calcite, Pyrite
Hampstead Farm Quarry, Chipping Sodbury, Gloucestershire, England, UK
Overall height is 45mm
It shows separate calcite growth phases very clearly, the earlier phase being coated with a later phase of pyrite.

Photo & Specimen kindly supplied by Ian Jones. Thanks Ian!
