Siderite cleavage
Web(n) siderite Native iron protocarbonate, a mineral of a yellowish or brownish color, crystallizing in the rhombohedral system with perfect rhombohedral cleavage. It is isomorphous with calcite (calcium carbonate) and the other rhombohedral carbonates of magnesium, zinc, and manganese. Weblimonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite. The name limonite properly should be restricted to …

WebRegardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite. In Early Proterozoic (2.5 to 1.6 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as Banded Iron … WebTo produce fresh (1014) surfaces, cleavage was assisted on euhedral siderite rhombs by repeatedly scoring the surface coincident with the cleavage directions and applying a small force. This method is known to produce broad terraces bounded by steps of up to several tens of nanometers on Iceland-spar calcite [7].
WebSiderite (pronounced SYE-der-ite) is a tan gemstone popular with collectors for its interesting crystal shape and rare faceted options. Though faceted options are popular display pieces, the low hardness and perfect siderite cleavage makes cutting it tricky, so jewelry is less common.
