Outcrop map of Glorieta Formation in New Mexico. |
The Glorieta Formation is a geologic formation in New Mexico. It is exposed in most of the flanking uplifts of the Rio Grande Rift[1] and extends in the subsurface to west Texas.[2] It is a massive white cliff-forming sandstone, fine to medium grained, that weathers to reddish brown. First named in 1915,[3] it was long considered either the uppermost member of the Yeso Formation or the lowermost member of the San Andreas Formation but was promoted to independent formation status in 1943.[1] It is particularly prominent in Glorieta Pass but extends west to the Jemez Mountains (where it pinches out in the central Nacimiento Mountains) and south to the Socorro area.[1][4]
The Glorieta Formation is of Kungurian age and is likely a shallow marine equivalent of the Coconino Sandstone of Arizona, from which it was separated by the Defiance uplift.[5] It is regionally uniform and shows cross stratification suggesting subaqueous deposition, except for local coastal eolian deposition.[6]
