Sphalerite, Galena and Calcite 1 (CWO)

Nantiago mine, Central Wales Orefield. Sphalerite and galena filling crevices in fractured calcite. The sphalerite is a coarse aggregate with a very deep red colouration, and the galena is mostly in the form of cubo-octahedral crystals. The ratio is approximately 90:10% in favour of the sphalerite.
