Glad You Asked What Are Moqui Marbles Utah Geological

A very thin, microscopic layer of hematite an iron oxide mineral coated the sand grains, giving the sand its red color. The sand was later buried by other sediments and eventually cemented into sandstone, during which time the hematite coatings continued to spread over the grains, ultimately giving us some of the most spectacular red ...

Sandstone. Sandstone is composed of mineral grains commonly quartz cemented together by silica, iron oxide, or calcium carbonate. Sandstones are typically white, gray, brown, or red. Red and brown sandstones are colored by iron oxide impurities. Most sandstones feel gritty, and some are easily crushed friable and break up to form sand.
