Siderite is a common mineral and is found worldwide in many different environments. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal. Excellent gemmy greenish crystals come from Isere, (especially at Allevard), France.
Siderite is also the name of a type of iron meteorite.Siderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.
Siderite, iron carbonate (FeCO3), a widespread mineral that is an ore of iron. The mineral commonly occurs in thin beds with shales, clay, or coal seams (as sedimentary deposits) and in hydrothermal metallic veins (as gangue, or waste rock). Manganese (Mn), magnesium (Mg), and calcium generally
An unnecessary name for a manganoan variety of siderite, with up to 40% MnCO3 [Clark, 1993 - "Hey's Mineral Index"]. Pistomesite Obsolete name for a magnesian variety of siderite with the Fe:Mg atomic ratio ranging from 70:30 to 50:50.
Siderite is a member of calcite group minerals, which have a similar structure and form several solid-solution series. The miscibility of the calcite group members is limited though. Of the several possible members of the solid-solution series associated with siderite (FeCO 3), only the smithsonite (ZnCO 3), magnesite (MgCO 3) and rhodochrosite (MnCO 3) varieties are common.
Siderite is a carbonate mineral (FeCO 3). It is not rare but nowhere as common carbonate as calcite (CaCO 3) and dolomite (CaMg(CO 3) 2). Typically to carbonates, siderite also forms rhombohedral crystals. It shares the same crystal structure with calcite, but there is no solid solution between them because Ca and Fe ions are significantly different in size. There is,
Although Siderite is a relatively common mineral at Tsumeb, occurring in each of the three oxidation zones, specimens are not that often seen in collections because aesthetic specimens tend to be very rare. A 2.2 cm by 0.5 to 1.0 cm wide patch of well crystallised, gemmy-brownish-yellow Siderite sits on a germanium-rich sulphide matrix with a play of peacock-blue iridescence. A few Siderite ...
Dolomite, ankerite, siderite and quartz (chert) are the dominant gangue minerals, and important alteration minerals in most SEDEX deposits. However, the extent and intensity of alteration are typically much less than in VMS deposits, reflecting the lower temperatures and higher pH of the fluids. Hydrothermal alteration is most prominent within and adjacent to the vent complex, in

HISTORY, NAME, LOCALITIES: Siderite, pronounced SYE-der-ite, has been known since antiquity and was recognized as mineral species in 1845. Its name stems from the Greek sideros, meaning “iron,” alluding to its composition. Siderite is abundant and widely distributed with notable collecting localities in Germany, England, Portugal, South Africa, Bolivia, Canada, and the United States ...

Siderite is a common mineral although excellent, attractive crystal specimens are sometimes hard to find. But many crystals, when colorfully iridescent, make a wonderful, colorful, satiny, shimmering mineral specimen. The iridescence is probably caused by a surface alteration to the iron oxide, goethite. Further alteration of siderite crystals can result in pseudomorphs. The amorphous iron ...

Siderite is a iron carbonate mineral found in sedimentary, shales, clays and bog deposits. Siderite also forms in hydrothermal deposits and in nepheline syenite pegamtites and forms a series with Rhodochrosite. Siderite becomes magnetic when heated (paramagnetic). Metaphysical Properties. Siderite acts on all chakras and is excellent at aligning the meridians and subtle bodies. Siderite

11/08/2014 Siderite is a type of mineral that is composed of iron (II) carbonate (FeCO 3). Its name comes from the Greek term "sideros" which means iron. It is an essential iron mineral, as it is composed of 48% iron without phosphorus or sulfur. This mineral is classified as calcite which is a cluster of carbonates that are all considered isomorphous. This mineral is characterized by an absolute ...

The 2‐mm‐thick siderite precipitates around the steel ball in the incubated sediment suggest that alkalinity is the limiting factor for siderite minerals to precipitate during bacterial iron reduction while iron is the limiting factor when sulfate reduction begins. Without the increased alkalinity and the presence of effective nucleus, the formation of siderite is unlikely (or delayed ...
