Cerussite after Anglesite with Coronadite

A large cabinet specimen of sooty black Coronadite thickly coating crystals of Cerussite forming excellent pseudomorphs after Anglesite from the Broken Hill mining district in New South Wales, Australia. The specimen is complex in the underlying crystal morphology and structure, containing rhombic crystals to almost 2 cm and elongated stalactitic rods to at least 6 cm long. The Coronadite, an oxide of lead and manganese forms acicular crystallised crusts of 2 to 3 mm thick over the Cerussite pseudomorphs and in certain areas display the internal structure of needle like rods.
