Plume-lithosphere interaction in generation of the Emeishan flood basalts at the Permian-Triassic boundary [PDF]
Geology, 1995 The Emeishan flood volcanism that erupted at Permian-Triassic boundary time produced a large igneous province of at least 2.5 X 10 5 km 2 in the western margin of the Yangtze craton, southwestern China. The volcanic successions, suggested to have resulted from a starting mantle plume, comprise thick piles of basaltic flows and subordinate picrites ...

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Superchrons represent critical phases in geomagnetic field evolution, offering insights into Earth's distinct internal states. However, the lack of research on how the longest Phanerozoic superchron (Permo‐Carboniferous Reverse Superchron, PCRS, ∼318–263 Ma) terminated limits our understanding of the geodynamic processes and the interaction ...

Bulk magnetic domain stability controls paleointensity fidelity [PDF]
, 2017 Nonideal, nonsingle-domain magnetic grains are ubiquitous in rocks; however, they can have a detrimental impact on the fidelity of paleomagnetic records—in particular the determination of ancient magnetic field strength (paleointensity), a key means of ...

Palaeomagnetic re-investigation of early permian rift basalts from the Baoshan block, SW China: Constraints on the site-of-origin of the gondwana-derived eastern cimmerian terranes [PDF]
, 2013 A palaeomagnetic investigation was carried out on a series of rift basalts (Woniusi Formation) that accumulated on the Baoshan block (SW China) in the Early Permian, the aim being to provide quantitative palaeogeographical information on the eastern ...
