WAUPACA COUNTY: Siderite, pseudomorphically replaced by goethite, was reported from road cuts in pegmatite cutting granite along County G near Keller Lake, NE of Big Falls. Associated minerals include euxeniteY, biotite, fluorite, K feldspar, bastnaesite group minerals, allanite and various sulfides Tom Buchholz, 2002, personal communication.

2018427Goethite can also occur in stalactitic or massive forms and in tufts and drusy coatings. Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the

Last Note From Plymouth: Siderite Sighting

2019217Siderite is an iron mineral, of which I am only now reading about. Apparently, siderite is valuable mineral in theory since it contains a high amount of iron, possibly 48. In such a small outcropping it is totally uneconomic but an interesting curiosity to any rockhound or mineral collector walking the woods.

Synthesis of magnetite powder from the mixture

2018615Increasing the treatment time from 10 to 20 min does not lead to a significant change in the saturation magnetization of the resulting samples. This means that siderite in the mixture is completely decomposed into magnetite by heating at 600 C for the first 10 min.

Goethite often forms through the weathering of other ironrich minerals, and thus is a common component of soils, concentrated in laterite soils. The formation of goethite is marked by the oxidation state change of Fe 2 ferrous to Fe 3 ferric, which allows for goethite to exist at surface conditions.

The microbially driven formation of siderite in salt

2019128The change in the 13 C carbonate of the siderite concretions reflects a change in the 13 C of the DIC pool from which the concretion is growing, also supporting the idea that the concretions may nucleate in one position in the salt marsh and grow further in another. The salt marsh platform is a dynamic sedimentary environment, and through ...
