An simply outstanding Mendip specimen with a large crystal lined cavity inside a Manganese Oxide mass. The void contains choice Cerussite and Hydrocerussite some in twins and others with reticulated forms, nestled on a sparkling Calcite. This Quarry is famed for the rare Lead minerals that are found here in association with the Manganese deposits in the Carboniferous Limestones. The location is unique and has been the source of at least eight new minerals. That said most of the specimens are not often well crystallized or esthetic. This is an exception as the Lead minerals are well formed and make an attractive display contrasting inside the cavity. The Merehead Quarry now known as the Tor Works Quarry began to be noticed about 80 years ago and is a world class source of many other rare species.
