Summary:At High Sedling mine, Cowshill, Weardale, the complex hydrated calcium silicate carbonate sulphate mineral thaumasite occurs as crusts of soft white spherules ≤ 0.25 mm across, accompanied by dark limonitic material on pale brown mudstones. At Shap Blue quarry, Shap, a few blocky hexagonal crystals of thaumasite ≤ 0.7 mm across encrust prehnite crystals lining small cavities in compact crystalline prehnite found as segregations in garnet-epidote veins.
