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.

Olivine-rich achondrites from Vesta and the missing mantle problem
Nature Communications, 2021 Ultramafic olivine-rich achondrites provide insight into the missing mantle problem in the asteroid belt. The petrology and geochemistry of these samples suggests they are related to Vesta or the Vestoids.

Thermoelastic Properties of Liquid Fe‐Rich Alloys Under Martian Core Conditions
Geophysical Research Letters, 2023 Seismic measurements made on Mars indicate that the liquid iron‐nickel core is rich in light elements; however, the effects of these light components on the elasticity of Mars’ core remain poorly constrained.

Temperatures in ambient mantle and plumes: Constraints from basalts, picrites, and komatiites [PDF]
, 2006 Several methods have been developed to assess the thermal state of the mantle below oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of erupted lavas. One leads to the conclusion that mantle potential temperature (i.e.
