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
[edit | edit source]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
[edit | edit source]The unit was first named as the Queen sandstone of the upper San Andres Formation by Grant Blanchard and Morgan Davis in 1929.[3] In 1937, W.B. 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 Ronald DeFord and Russell Lloyd in 1940.[7] The formation was assigned to the Artesia Group by D.B. Tait and coinvestigators in 1962.[1]
