Jacobsville Sandstone is a red sandstone formation, marked with light-colored streaks and spots, primarily found in northern Upper Michigan, portions of Ontario, and under much of Lake Superior. Desired for its durability and aesthetics, the sandstone was used as an architectural building stone in both Canada and the United States.
Exeter, Devon, ancient city walls of Isca Dumnoniorum with medieval and Roman elements. The New Red Sandstone, chiefly in British geology, is composed of beds of red sandstone and associated rocks laid down throughout the Permian (300 million years ago) to the end of the Triassic (about 200 million years ago), that underlie the Jurassic-Triassic age Penarth Group.

Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate , marl , limestone , or some combination of these sedimentary rocks.
Danxia landforms are made up of uplifted continental crust that has been faulted and eroded, exposing large scarps of layered rock, red in color. [4] Danxia landforms cover several provinces in southeast China. Taining County, Fujian Province, has very good examples of "young" danxia landforms wherein deep, narrow valleys have been formed. As ...
The formation is the most prominent layer of the red rocks of the Sedona area due the presence of hematite – iron-oxide (rust) – giving the sandstone a red color. The Schnebly Hill Sandstone formation comprises three sections: the Bell Rock member, the Fort Apache member, and; the Sycamore Pass member. [7]

The geology of the national park consists of a thick succession of sedimentary rocks laid down from the late Ordovician through the Silurian and Devonian to the late Carboniferous period. The rock sequence most closely associated with the park is the Old Red Sandstone from which most of its mountains are formed.
Old Red Sandstone, abbreviated ORS, 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 eastern seaboard of North America .
