Earthquake early warning (EEW) systems are crucial for mitigating seismic hazards. Current EEW algorithms predominantly rely on seismic data (Allen and Melgar, 2019) and can be classified into three main categories: point‐source, finite‐fault, and ground‐motion‐model based.The extracted heavy-mineral concentrates were sieved into four fractions: <0.1 mm, 0.1–0.25 mm, 0.25–0.5 mm, and >0.5 mm. Magnetic minerals from each fraction were separated using a very weak magnet. Since awaruite is more magnetic than magnetite, its proportion in the resulting concentrate was high.The end-Permian extinction (EPE), the most severe biotic crisis of the Phanerozoic (Wignall, 2015), led to the fundamental restructuring of terrestrial and marine ecosystems.The consensus view is that the EPE occurred as a consequence of Siberian Traps volcanism, which generated large volumes of sulfate aerosols and CO 2 over a …“GeoScienceWorld provides small research institutions like mine with cost-effective access to a world-class library of geoscience literature—much more than we could ever afford to subscribe to otherwise.
