Fluorspar, Galena & Sphalerite

Weardale was a main source of minerals such as lead  ore (galena),   fluorspar (calcim fluoride)., sphalerite (zinc sulphide), quartz, and calcite. These minerals was formed over 255 million years ago when the granite dome under the dale expanded allowing hot  chemical solutions to be rise up into the overlying limestones. These solutions crystalised out in the cracks in the limestones where they were mined from Roman times from what was known as the North Pennines Ore Field. Mining has now ceased but the attractive crystals are much prized by mineral collectors.
