An amazing El Hammom specimen
El Hammam is known for producing some very interesting mineral combinations, including quart calcite fluorite barite and various oxides. This specimen is an excellent example of what can come from this site. One side consists of calcite crystals and the other quartz crystals.
The calcite has inclusions where pyrolusite has grown over the calcite crystals, with the calcite continuing to grow and some covering the pyrolusite while others still have exposed or partially exposed pyrolusite. Then a growth of pyrite covers some of the calcite.
The quartz has a coating of siderite giving it a golden-brown colour. There is further botryoidal pyrolusite growing over small patches of the quartz. There is also a small additional growth of calcite that is free from and iron and manganese.
