Pink and porcelain-white Magnet Cove, Arkansas novaculite with pisolitic hematite. The hematite pisolites have a curious "exploding sun" effect up close, with tiny red bits scattered away from the core into the white/pink areas. Novaculite is a variety of mildly metamorphic ...The results indicate that LO1 (loss on ignition) in iron ores have a positive influence on FeO formation by promoting the sintering process of Fe2 O3 decomposing and reducing. Silica contents in iron ores play a determining role in final content of FeO in sinter. The melting characteristics of iron ores significantly affect FeO formation during ...

pisolite: [noun] a limestone composed of pisiform concretions. The adjective "pisolitic" denotes mineral aggregates (usually carbonates) with a concentric structure, forming spheres with a diameter greater than 2 mm (pisolites).These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. The Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: ...New ore types such as hematite/goethite ores from deposits in the Marra Mamba iron formation, pisolitic ore from Channel Iron Deposits (CID), and detrital ores from Detrital Iron Ore Deposits (DID) are now either being mined or are under development to increase export tonnages and supplement the reserves of the traditional premium grade ...

The Eocene rocks of this area are economically important as they yield coal from the pyritic shales. The pisolitic bauxite forming a part of the Subathu series is considered suitable for a refractory use.

Pisolites and Oncoids. Pisolites, oncoids, and oncolites are enveloped by irregular layers. All these grains are frequently larger than ooids and commonly are over a centimeter in diameter. Pisolites form by the precipitation of calcium Carbonate around nuclei trapped in sediment within the vadose zone of soils or marine tidal flats (Figure 24).Over the strongest part of the multi-element anomaly, the following levels in ppm are reached in the pisolitic laterite: As 1150, Sb 75, Sn 4200, Nb 75, Ta 75, W 30, Li 100, B 500 and Be 60.
