Siderite (FeCO 3) is an iron-bearing carbonate common to many diverse sedimentary settings, particularly in marine and lacustrine environments (Baker and Burns 1985; Ellwood et al. 1988; Ranganthan and Tye 1986) and in hydrothermal veins (French 1971). Substitution of Fe+2 by other metallic ions is common in siderite and the mineral is rarely ...

Spheroidal siderite is often inferred to be a water-column precipitate and precursor for rhombohedral and cemented diagenetic siderites in Precambrian rocks (Konhauser et al., 2005; Köhler et al., 2013). In contrast, the preservation of residual phases trapped in spheroidal mosaic siderite crystals in Lake Towuti may, if primary, suggest ...

Mineral Database | National Museum Wales

Introduction: siderite is widely developed in a range of geological settings, in particular some hydrothermal veins (where it may be the chief gangue mineral and may also be mined if pure enough), and in sedimentary rocks, where it is often an important constituent of ironstones. Siderite, like other iron-bearing carbonates, is white to creamy-yellow when unweathered: however it does weather ...
