  • Oceanic island basalts have much lower eruption rates than lavas from large igneous provinces, but a quantitative petrological comparison of lava sources has not been made. Claude Herzberg and Esteban Gazel have examined the composition of Galápagos-related lavas, and conclude that the mantle plumes that generated large igneous provinces in the Permian to Palaeocene periods were hotter and melted more extensively than the plumes that produced modern oceanic islands.

  • Several nickel-rich and helium-rich lava samples from ocean islands and large igneous provinces suggest that mantle plume material formed by core–mantle interaction during the crystallization of a melt-rich layer or basal magma ocean.

  • Transient absorption spectroscopy is used to identify the structural characteristics of the atoms and molecules. Here the authors used extreme ultraviolet transient absorption spectroscopy to identify the Rydberg state symmetry of aligned molecules.

  • The Archaean Earth was much hotter than today. Numerical modelling shows that the base of thickened crust that formed at the time would have been so dense that it dripped back into the mantle.

  • Tectonic plate motions are often reconstructed based on the assumption that mantle plumes are fixed within the mantle. Here, the authors provide geochemical and geodynamic evidence to suggest that the asymmetry of the Azores thermal anomaly can be explained by northward motion of the Azores plume.

  • How does Hawaii look deep below the surface? Like viewing an object at a different magnification, studies of minuscule inclusions in volcanic rocks on the surface provide a fresh perspective on the question.
