The Victorio Peak Formation is a geologic formation found in the Delaware Basin in Texas and New Mexico. It preserves fossils dating back to the Leonardian Age of the Permian Period.[1]
The formation consists of light gray limestone and dolomite[1] The total thickness over 1,000 meters (3,300 ft).[2] The base of the formation is largely concealed in the subsurface, and the formation is overlain by the Cutoff Shale.[1] The formation grades laterally to the southeast into the Bone Spring Formation, representing the change from shallow shelf carbonate deposition to deep marine carbonate deposition. To the northwest, the Victorio Peak Formation grades into the Yeso Group and the lower part of the San Andres Formation.[3][4]
Fossils
The formation contains fossil brachiopods, include Productus ivesii,[5] Dichtyoclostus, and Neospirifer, fusulinids such as Parafusilina, crinoids, corals, and euomphalid gastropods[6] characteristic of the Leonardian.
