Lithology and environment
Primary lithology:tabular,planar lamination,concretionary,red poorly lithified silty,calcareous sandstone
Includes fossils?Y
Lithology description: vivid red to orange, poorly cemented sandstone, with sandy concretions of variable size, small, white calcareous concretions occur. Some silt and clay intercalations. Cross-stratification is rare, but horizontally layered and massive beds are common. Common trace fossils - sediment-filled tubes - within the Red Beds. "In the profile Khermeen Tsav II the thick-bedded sandstones are orange-coloured and numerous intercalations of light-coloured (white, yellow, pale-red, and bluish-green) thin-bedded siltstones and claystones are present." (10453)
Environment:terrestrial indet.
