| Species: | Wulfenite | |
| Formula: | Pb(MoO4) | |
| Comments: | Most Merehead (and Mendip) wulfenite occurs as honey-yellow blades in a matrix of mixed carbonates (usually calcite and/or cerussite and/or aragonite). Blades are usually <5mm and most are smaller; smaller specimens tend to be more yellow in colour. Larger blades have been known to occur on two occasions. Honey-yellow blades were found in June 2006, up to 25mm in size with one specimen reaching 75mm (but unfortunately, all had been caught by the blast). An old specimen in the NHM collection contains a single, red-brown blade approximately 70mm in size. These are probably the largest UK specimens of wulfenite. Free-standing crystals are very rare and generally very small. | |
