Magnetic Records of Extreme Geological Events

Magnetic Records of Extreme Geological Events

Geological

Life on Earth was punctuated by several dramatic paleoenvironmental and paleoclimatic changes leading to mass extinction linked to continental flood basalts (CFBs) and large igneous provinces (LIPs), global oceanic anoxic events (OAE), rapid climate and sea level changes and meteorite impacts. On a global basis, linking the mass extinction to LIPs volcanism has remained problematic due to insufficient accuracy in radiometric dating. In the case of the Cretaceous-Tertiary (KT) mass extinction, identifying the very short geological interval between Deccan Traps and the Meteorite impact has remained problematic and calls for new approaches. Likewise precise age control between LIPs and mass extinctions for the Jurassic/Triassic, Permo/Triassic, Mid-Permian, and end-Devonian are in need of further age refinement.
