The Queen Formation is a geologic formation in southeastern New Mexico and west Texas. It preserves fossils dating back to the late Guadalupian Epoch of the Permian period.{{sfn|Tait|Motts|Spitler|1962}}{{sfn|Kues|Giles|2004|p=100}}
Description
The formation consists of up to {{convert|500|feet|meters}}{{sfn|Blanchard|Davis|1929}} of mostly sandstone, with some interbedded dolomite and anhydrite. It rests on the San Andres Formation, from which it is separated by an erosional surface showing karst features.{{sfn|Kues|Giles|2004|pp=124-128}} The Queen Formation is overlain by the Seven Rivers Formation. The Queen Formation is part of the Artesia Group, which is interpreted as a sequence of shelf rocks of the Capitan reef.{{sfn|Tait|Motts|Spitler|1962}}{{sfn|Kues|2006}}
History of investigation
The unit was first named as the Queen sandstone of the upper San Andres Formation by Grant Blanchard and Morgan Davis in 1929.{{sfn|Blanchard|Davis|1929}} In 1937, W.B. Lang assigned the Seven Rivers Member to the (now abandoned) Chalk Bluff Formation.{{sfn|Lang|1937}} The unit was promoted to formation rank and assigned to the Whitehorse Group by Ronald DeFord and Russell Lloyd in 1940.{{sfn|DeFord|Lloyd|1940}} The formation was assigned to the Artesia Group by D.B. Tait and coinvestigators in 1962.{{sfn|Tait|Motts|Spitler|1962}}
