The Cherry Canyon Formation is a geologic formation found in the Delaware Basin of southeastern New Mexico and western Texas. It contains fossils characteristic of the Guadalupian Age of the Permian Period. [1]
The formation consists mostly of cyclic marine sandstone and siltstone, but with interfingering tongues of gray limestone (the Getaway, South Wells, [2] and Manzanita Members). These extend from the Goat Seep reef, an earlier and much smaller precursor to the Capitan reef, into what was then deep, anoxic water of the Permian Basin. A lower tongue of the formation extends across the basin margin to grade into the nearby San Andres Formation. Maximum thickness of the Cherry Canyon Formation is 400 meters (1,300 ft). The formation rests on the Brushy Canyon Formation, but the lower tongue fills a few deep paleochannels that cut down through the Brushy Canyon and the underlying Cutoff Formation into the Victorio Peak Formation. [3] A hiatus in deposition, marking a substantial drop in sea level, separates the Cherry Canyon Formation from the overlying Bell Canyon Formation. [4]
The Getaway Member contains carbonate debris flow beds. All three carbonate members grade into sandstone channel deposits deeper in the basin. [3]
The formation contain abundant fish fossils, such as sharks' teeth, preserved within small phosphatic nodules. [5] Ostracods have been identified in the Getaway Member, including Amphissites , Aurikirkbya , Ceratobairdia , Polytylites , and Roundyella . [6]
The Cherry Canyon Formation has been exploited for its hydrocarbon resources. [7] Some of the hydrocarbons present in the formation may have leaked into nearby gypsum beds of the Castile Formation, producing sulfuric acid that contributed to the formation of Carlsbad Cavern. [8]
The unit was first designated as a formation by DeFord and Lloyd in 1940, who raised the Delaware Mountain Formation to group rank and designed its previously informal members as formations. [9] [10]
The Permian Basin is a large sedimentary basin in the southwestern part of the United States. It is the highest producing oil field in the United States, producing an average of 4.2 million barrels of crude oil per day in 2019. This sedimentary basin is located in western Texas and southeastern New Mexico. It reaches from just south of Lubbock, past Midland and Odessa, south nearly to the Rio Grande River in southern West Central Texas, and extending westward into the southeastern part of New Mexico. It is so named because it has one of the world's thickest deposits of rocks from the Permian geologic period. The greater Permian Basin comprises several component basins; of these, the Midland Basin is the largest, Delaware Basin is the second largest, and Marfa Basin is the smallest. The Permian Basin covers more than 86,000 square miles (220,000 km2), and extends across an area approximately 250 miles (400 km) wide and 300 miles (480 km) long.
The Cutler Formation or Cutler Group is a rock unit that is exposed across the U.S. states of Arizona, northwest New Mexico, southeast Utah and southwest Colorado. It was laid down in the Early Permian during the Wolfcampian epoch.
