Name (s) in local language (s): Miniera di Motto Piombino, Gignese, Verbano-Cusio-Ossola, Piemonte, Italia. Motto Piombino was in the past the most importan Pb-Zn mine in the Alto Vergante-Agogna Valley region. The beginning of the works date back to 1861, when an English company directed by Eng. Eugene Francfort started to operate in the place.
The mines have all kinds of iron minerals like limonite, hematite, pyrite, and siderite. Miniere Gaffione is rather famous for being the source of beautiful aragonite crystals which are still sold at mineral fairs. The mine is operated by SKI-MINE. They also operate the mines Sant'Aloisio, Marzoli, and Gambatesa. Keep the ticket if you visit ...

Ancient sedimentary iron formations (IFs) are composed of diverse iron oxides, silicates, and carbonates that are thought to form through diagenesis and subsequent metamorphism of primary ferric-ferrous (Fe 3+ -Fe 2+) iron (oxyhydr)oxide precipitates ( Gole, 1980; Raiswell et al., 2011 ). Yet iron carbonate minerals such as …

Siderite is an iron carbonate mineral (FeCO 3, 48% Fe) belonging to the calcite group (hexagonal crystal system). Magnesium and manganese may substitute for the iron. Siderite crystals are yellow to dark brown in color, rhombohedral in shape, and with curved and striated faces, and also occur in masses. Siderite is commonly found in bedded ...

La sidérite est une pierre précieuse brune appréciée des collectionneurs pour sa forme cristalline attrayante et ses rares options à facettes. Bien que l'option à facettes soit une coupe de présentation populaire, la faible dureté de la sidérite et son clivage parfait la rendent difficile à couper, ce qui la rend moins courante en bijouterie. …
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 ...
Siderite (FeCO3) is an iron-bearing carbonate mineral that is the most abundant sedimentary iron formation on Earth. Mineralogical alteration of four siderite samples annealed at temperatures 200 °C, 300 °C, 400 °C, 500 °C, 750 °C, and 1000 °C in an O2 and a CO2 atmosphere were investigated using such tools as X-ray diffraction …

The meaning of siderite crystals goes beyond their physical composition. Siderite is believed to be a stone of transformation and inner strength. It is associated with grounding energy and stability, helping individuals overcome challenges and embrace personal growth. The crystals are thought to promote harmony, balance, and emotional …
The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
Siderite is a carbonate mineral of iron. It has the composition FeCO 3. The origin of this sample is Lukmanierschlucht, Grissons, Medel, Switzerland. It is on display in the Smithsonian Museum of Natural History. The sample measures about 12x12 cm.

Siderite is a mineral composed of iron carbonate . Its name comes from the Ancient Greek word σίδηρος, meaning "iron". A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus. Zinc, magnesium, and manganese commonly substitute for the iron, resulting in the siderite-smithsonite, siderite-magnesite, and siderite-rhodochrosite …

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.
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…
