Iron oxide and clay minerals and their relation to colours
The iron oxide and clay minerals in some typical red and yellow podzolic soils from New South Wales have been investigated by Xray diffraction and infrared spectroscopy. The dominant iron oxide mineral is goethite containing about 1314 tool % A1OOH, this being the mineral which gives the yellow soils their characteristic colour.

J. Wollschläger, in Encyclopedia of Interfacial Chemistry, 2018. Abstract. Iron oxide films can show very different stoichiometries due to the flexibility of their Fe oxidation state Fe 2 + /Fe 3 +.This flexibility is accompanied by the formation of various singlecrystalline phases e.g., hematite, magnetite, maghemite, and wüstite with different chemical and physical properties.

Diagenetic Patterns of the Cretaceous Baseline Sandstone
The Cretaceous Baseline Sandstone of the Sevier foreland basin deposits in southern Nevada exhibits intense diagenetic ironoxide coloration and bleaching, and contains abundant cemented masses. The Baseline Formation is ~1 km thick with three alluvial to fluvial members: the basal White Kbw Member, overlain by coeval Red Kbr and Overton Conglomerate Kbo Members.

Old Red SandstoneWikipedia
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America.It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica/Laurussia.

IronOxide Concretions and Nodules, 1Some Meteorite
Hematite and magnetite are two 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 shapes catch peoples attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.

However, the size of iron oxide precipitate particles is limited by the sandstone pore size, which is typically smaller than tens of microns 17,18. Note that a typical particle size of iron oxide in Navajo Sandstone is ~10 mcrometers 3. Thus, iron oxide precipitates confined in these pores remain effective almost forever for Ostwald ripening.

The color of sandstone varies, depending on its composition. Argillaceous sandstones are often gray to blue. Because it is composed of light colored minerals, sandstone is typically light tan in color. Other elements, however, create colors in sandstone.
