Hydrozincite and calcite

This calcite and hydrozincite combo comes from an old Belgian lead/zinc mine near Plombières, Liège province, Belgium. The locality is no longer accessible since it's been turned into a parking lot. One could actually find 3-color specimens there: yellowish, red and blue (gypsum, calcite and hydrozincite).
