A classic plate of black sphalerite crystals and flattened, spinel-law twinned galena crystals. The sulphides have clusters of small quartz, calcite and dolomite crystals between them to enhance the presence of the darker crystals. The galena crystals are particularly good examples of spinel-law twinning. Very nice!
