Iron-Oxide Concretions and Nodules, 1 Some Meteorite

Iron-oxide nodules or concretions are the most common kind of meteorwrong sent to us. Hematite and magnetite are two common iron-oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because their unusual, frequently bizarre, shapes catch people’s attention and they

IRON OXIDE CONCRETIONS Yola

The iron oxide which comprises these concretions has been derived mainly from the chemical weather-ing of iron-rich minerals in local rocks. In particular, pyrite is abundant in some of the Cretaceous rocks, and this weathers rapidly on exposure to groundwater to form iron oxides.

Composition, nucleation, and growth of iron oxide concretions

Jan 01, 2011 Iron oxide concretions form in porous sandstone by chemical reduction and solution of iron minerals, transport of Fe 2+ in solution, and precipitation of hydrous ferric oxide by oxidation. Concretions form quickly in 1000's of years by diffusion and advection, and K-feldspar consumption of H + initiates nucleation.

Numerical simulation of iron oxide concretions on Earth

Feb 15, 2021 Iron oxide concretions are found in sedimentary rocks on both Earth and Mars. On Earth, concretions are common in eolian formations, such as the Jurassic Navajo Sandstone in Utah, USA and those found in the Cretaceous Djadokhta Formation, Gobi Desert, Mongolia.

She called them “Indian paint pots.” (See, for example, Garvies Point concretions). The stones are hematite concretions used by Native Americans to paint their faces.
