Siderite Mineral Specimen from Panasqueira Mine, Portugal air They are approximately 110–120 millionSiderite is an iron carbonate mineral with the chemical formula FeCO. Its key element, Iron (Fe), appears on the periodic table with the atomic number 26. Siderite crystallises in the trigonal system, forming rhombohedral crystals that range in colour from pale yellow to deep brown. Its lustre can be vitreous to pearly, and it is frequently found in association with minerals such as quartz, fluorapatite, cassiterite, and wolframite. This specimen
