"Morphologic Clues to the Origins of Iron Oxide–Cemented

Concretions cemented by iron oxide are abundant and diverse in the Jurassic Navajo Sandstone of southern Utah. Some of these structures are considered terrestrial analogs for concretions imaged on Mars. The Navajo concretions can be spheroidal pipelike or tabular with multicompartmented boxworks. These iron oxide concretions typically display a rinded structure dense sandstone rinds

Composition nucleation and growth of iron oxide concretions

Cemented sandstone occurs as spheroidal forms from mm to cm scale rinds buttons disks and large cylindrical pipes or columns some up to 10 m high. Strata bound layers of iron oxide cemented sandstone and conglomerate extend for 10s of meters (Chan et al. 2000 Chan et al. 2004 Chan et al. 2005).

Red Rock Canyon A to Z I is for Iron Oxide Red Rock

The shifting sands became buried by other sediments and eventually it was all cemented into sandstone with iron oxide and calcium carbonate. In some places the iron has concentrated and oxidized to reveal a rusty red coloring. This is what is now known as Aztec Sandstone prominently displayed in Calico Hills and the Red Rock cliffs.

Chronicles of vadose zone diagenesis cone‐shaped iron

Jan 20 2011 · Within this context we suggest the cone‐shaped Trujillo concretions are iron oxide cement and concretion structures that are important indicators for vadose zone conditions and the spatial distribution and direction of flow paths. Cubic crystal shapes at cone apices suggest pyrite (FeS 2) likely provided the initial iron source.
