Calcite on pyrite in septaria



Yellow calcite skalenohedra on a layer of irridiscent pyrite in septaria, Kontich, Atwerpen, Belgium. The white fluorescence (365 nm LED excitation) is coming from a strong emission in the blue part. Most probably caused by lattice defects, although organic acids are also a possibility since septaria grow in clay close to the surface.
