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.
Iron oxide (e.g. hematite, goethite) sandstone coloration and concretions are signiﬁcant indicators of the mobility of iron in groundwater and host rock properties such as por-osity and permeability. iron oxide concretions typically lack any obvious nucleus (chan et al. 2004, 2005) and appear to form in different ways from simple attractive.
Columns of iron-cemented sandstone. location: 10 miles (15 km) northwest of moab, utah. ... although red is the common pigment color, not all iron oxides are red; some are brown or yellow (minerals - limonite or goethite), and some are black (mineral - magnetite). some iron minerals are metallic yellow (mineral - pyrite.
These iron oxide concretions typically display a rinded structure: dense sandstone rinds cemented by iron oxide surround pale, iron-poor sandstone cores. within a single structure, the iron-rich rinds may be single or multiple. pseudomorphs of siderite are present in local residual, iron-rich cores of.
