Coronadite: Mineral information, data and localities.

Chemically related to (the Pb-richer) cesrolite.Many manganese oxides are better identified using infra-red spectroscopy than by x-ray diffraction because of issues of crystal size, disorder, etc. (Potter and Rossman, 1979). A possible precursor mineral is known: 'Unnamed (Amorphous Pb-Mn Hydroxide)'. Get price

Furthermore, this latter displays a substantial hardness (7.5 on the Mohs's scale), especially when it is combined with carbide anions in tungsten carbide (WC), which exhibits a hardness of 9. Tungsten presents a low abundance in the Earth crust, around 1.3 ppm, which is significantly lower than the other lithophile elements but about the same as that of tin (2 ppm) and molybdenum (1.2 ppm).
