Geophysical Monograph Series, Page 1-26., 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.

CONSEQUENCES OF INTERNAL HEAT FLOW IN RADIOISOTOPE HEAT SOURCES. [PDF]
, 1967 Equations relating the maximum internal temperatures of various-shaped fuel forms and other source parameters are given. By using calculated results, the use of cermets is compared with the use of oxide-metal laminar structures as methods of decreasing the resistance to heat flow in the interior of heat sources and achieving higher surface heat fluxes ...

Imaging the Earth's Interior: the Angular Distribution of Terrestrial Neutrinos
, 2004 Decays of radionuclides throughout the Earth's interior produce geothermal heat, but also are a source of antineutrinos. The (angle-integrated) geoneutrino flux places an integral constraint on the terrestrial radionuclide distribution. In this paper, we
