MG30AI6: A sample that reclaims a special attention, both for its spectacular appearance and for its complexity, because the Galena has the pseudomorph shape of parallel growths of old tabular Pyrrhotite crystals coated by Pyrite further recrystallized in small cubic and cubo-octahedral crystals, and with some twinned Sphalerite crystals. Being that the Pyrrhotite is after Galena and not Pyrite (which is the the most typical) the chemical stability of the sample seems assured.
