The Permian period

Geological Society, London, Special Publications, 2019
Summary Twelve rocks for which calculated isotopic ages are mutually consistent and for which there is some biostratigraphic control have been used in the construction of a Permian time-scale.

The Permian Paradox [PDF]

SSRN Electronic Journal, 2012
This paper arose out of discussions that took place during sessions of the Fourth Perm Economic Forum. A theme-based event, the Forum is held annually every September. In 2008, the theme of the Forum was urban development, including, naturally, development strategies for the city as a regional capital.

Permian-Triassic Rifting Stage

The Geology of Iberia: A Geodynamic Approach, 2019
The Permian-Triassic rifting represents the first of the two Mesozoic rifting stages recorded in the Iberian Peninsula. Its first phases of development started during the Early Permian, and were linked to the beginning of the break-up of Pangea, the large, unique and rheologically unstable supercontinent that mainly resulted from the collision of ...

Intensifying aeolian activity following the end‐Permian mass extinction: Evidence from the Late Permian–Early Triassic terrestrial sedimentary record of the Ordos Basin, North China

Sedimentology, 2020
Sedimentary successions provide direct evidence of climate and tectonics, and these give clues about the causes of the mass extinction around the Permian–Triassic boundary.

A sudden end-Permian mass extinction in South China

GSA Bulletin, 2018
Previous studies of the end-Permian mass extinction have established that it was geologically rapid, but condensed sections have made it difficult to establish the exact timing of the extinction relative to fluctuations in the ocean carbon cycle, oxygen ...

Organic carbon isotopes in terrestrial Permian-Triassic boundary sections of North China: Implications for global carbon cycle perturbations

GSA Bulletin, 2020
The end-Permian mass extinction (ca. 252 Ma) represents the most severe biotic crisis of the Phanerozoic, and it was accompanied by profound environmental perturbations, especially to the global carbon cycle, as indicated by sharp negative carbon ...
