Cover image by Conor O’Sullivan: Chevon folds in the Loughshinny Formation from Loughshinny Bay, north Co. Dublin. These Carboniferous limestones and mudstones were initially deposited in the Dublin Basin before being deformed during the Variscan Orogeny. A sharp unconformity separates these Carboniferous rocks from the overlying glacial deposits of the Dublin Boulder Clay, deposited during the Quaternary.

Aerial view of the Andes at the latitude of Santiago de Chile (33°20'), looking eastward. The Sierra del Coironal displays folded sedimentary rocks of the Cretaceous Formacion Colimapu. In the very foreground, the steeply dipping layers forming V-shaped outcrops mark the transition between the West Andean fold and thrust belt (in the west) and the shallower Aconcagua fold and thrust belt (in the east) (see e.g. Riesner et al., 2018). The highest summit in the background is the Tupungato volcano (6570m).

3D numerical model of a subduction zone, showing viscosity (background, Viridis colourmap), velocity field (black arrows), and two particles tracking deformation above (pink line) and behind (blue line) the slab. The modelling work aims to assess the importance of anisotropic viscosity of mantle olivine texture during subduction. See Wang et al. (2024) in this issue for more details.

Visually accessible and scientifically accurate global maps of key plate tectonics features on Earth. They show, from bottom to top: the Earth’s surface topography, the oceanic crust age, plate boundaries and tectonic plate names, active volcanoes, largest earthquakes, and the outlines of the world map with major rivers. See colour bar for oceanic crust ages in the Editorial Figure 1, page II.
