Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

LITHOSPHERIC MAGNETIC ANOMALIES IN THE TERRITORY OF SIBERIA (from measurements by the CHAMP satellite) [PDF]
Геология и геофизика, 2014 Abstract The position of lithospheric magnetic anomalies, detected in total magnetic intensity and the vertical component of the magnetic field, has been determined for Siberia using data from the CHAMP satellite. The paper describes the technique for the satellite data processing and the ways of recognition of regional lithospheric ...

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]
, 2002 Results from equivalent-source distributions derived jointly from high-altitude (average 4 km) aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada indicate that long-wavelength components (500–2500 km) in these fields are ...

Arctic and Asia lithospheric satellite magnetic anomalies
Physics of the Earth and Planetary Interiors, 1998 Abstract The polar regions present special problems in magnetic studies because they are largely inaccessible and contain the most disturbed magnetic fields on earth (e.g., effects from auroral phenomena). A processing method, previously developed for south polar satellite magnetic data (e.g., Magsat), is applied to north polar data to separate the ...

Teleseismic P‐Wave Attenuation Beneath the Southeastern United States
Geochemistry, Geophysics, Geosystems, 2021 Seismic attenuation is an important parameter for characterizing subsurface morphology and thermal structure. In this study, we use P‐wave amplitude spectra from 588 teleseismic events recorded by 477 broadband seismic stations in the southeastern United
