Hopes Nose: Mineralogy of SW EnglandDesignations: GCR (No. 1725), SSSI A nationally important site for mineral structures where hydrothermal fluids led to the formation of gold and rare palladium minerals GCR block / key theme: Mineralogy of south-west England Associated SSSI: Hope's Nose to Walls Hill SSSI GCR Statement of Interest: "A series of mineralised veins cutting through Devonian limestone are exposed in the rock platform on the eastern side of Hope's Nose. The vein fillings consist mostly of calcite, haematite and dolomite but small quantities of native gold also occur, as fine branching filaments. Recent detailed research has also revealed the presence of very rare palladium minerals (isomertieite and mertieite II). This is the only known occurrence of this assemblage of minerals in Britain, making this a nationally important site for mineralogical structures."
