Cherry Canyon Formation

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.
The formation consists mostly of cyclic marine sandstone and siltstone, but with interfingering tongues of gray limestone . 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 . 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. A hiatus in deposition, marking a substantial drop in sea level, separates the Cherry Canyon Formation from the overlying Bell Canyon Formation.
