Permian Period
Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins near the end of the Permian Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.
Permian rocks are widely distributed across the globe, reflecting the diverse geological and climatic conditions of the period. Their occurrence is generally categorized by their depositional environment and paleolatitude.12
Major Regions of Occurrence
- North America: Extensive deposits are found in the United States, particularly in the Permian Basin of West Texas and New Mexico, as well as in Oklahoma, Kansas, and the western United States (including Montana, Idaho, Wyoming, Utah, and Nevada).132
- Europe and Russia: Significant deposits exist in the Ural Mountains region of Russia, which serves as the type area for the Permian System. Other notable locations include the Zechstein Basin of northwestern Europe and areas along the Russian Platform.4512
- Gondwana and High Latitudes: Permian rocks, including tillite and coal-bearing successions, are found in regions that were at higher paleolatitudes during the period, such as Australia, peninsular India, South Africa, Zimbabwe, the Congo, southern Tibet, southern Thailand, and northeastern Siberia.12
- South America: Permian beds are present in the Paraná Basin of southern Brazil and the Precordillera Basin of western Argentina.1
