Queen Formation
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.[1][2]

Description
The formation consists of up[ to 500 feet (150 m)[3] 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.[4] 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.[1][5]
History of investigation
The unit was first named as the Queen sandstone of the upper San Andres Formation by Blanchard and Davis in 1929[3] In 1937, Lang assigned the Seven Rivers Member to the (now abandoned) Chalk Bluff Formation.[6] The unit was promoted to formation rank and assigned to the Whitehorse Group by DeFord and Lloyd in 1940.[7] The foramtion was assigned to the Artesia Group by Tait et al. in 1962.[1]
