  • Siderite - Wikipedia
    Siderite is a mineral composed of iron (II) carbonate (FeCO 3) Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron" A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus
  • Siderite: Mineral information, data and localities.
    Most often found in bedded sedimentary deposits with a biological component, with shales, clays and coal beds - suggesting that the siderite is biogenically created under low-oxygen and low-Ph conditions
  • Siderite | Iron Carbonate, Carbonate Minerals, Sedimentary Rocks . . .
    siderite, iron carbonate (FeCO 3), 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)
  • Siderite - Mineral Properties, Photos and Occurence
    Siderite is both an iron ore and gangue mineral Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical properties, and rhombohedral crystal form
  • Siderite - Details and Facts - allmineralsrock
    Siderite, also known as iron carbonate, is a mineral that is commonly found in sedimentary rocks such as limestone and shale It typically forms in low-temperature hydrothermal veins and can also be found in hot springs and as a precipitate in lakes and oceans
  • Siderite Mineral Data
    Primarily bedded, biosedimentary deposits, also in metamorphic and igneous rocks Forms a series with rhocochrosite Common world wide Link to MinDat org Location Data From the Greek sideros, "iron " Comments: White, metallic arsenopyrite and tan siderite crystals Location: Panasqueira (2000, 3rd level), in the region of Beira Baixa, Portugal
  • Siderite – WGNHS – UW–Madison
    Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore
  • Siderite - an overview | ScienceDirect Topics
    Siderite —The mineral form of iron (II) carbonate, with the chemical formula Fe 2 CO 3 is called siderite The mineral contains around 40%–48% iron and is a primary component of sedimentary rocks that assembles into the surrounding water bodies
  • Siderite: The mineral Siderite information and pictures
    Siderite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series
  • Siderite: A Comprehensive Examination of Iron Carbonate
    Siderite is primarily made up of iron carbonate, with the chemical formula FeCO₃ As a carbonate mineral, it belongs to a larger family that includes calcite and dolomite Siderite forms through precipitation from various geological processes, often associated with iron-rich environments
