Modeling of ionic diffusion in natural crystals has been developed over the last three decades to calculate timescales of geological processes. As the number of studies and the size of data sets have expanded, improvements in the precision of the gen

Meteorite impacts load the atmosphere with dust and cover the Earth9s surface with debris. They have long been debated as a trigger of mass extinctions throughout Earth history. Impact winters generally last Supplementary material: Extended Fig. 1 fr

The first products of the current Cumbre Vieja eruption comprise simultaneous tephra fall from near-continuous, gas-rich eruption plumes and lava flows. From combined field, petrographic and geochemical analyses we identify: low percentage mantle mel

X-ray laboratory diffraction contrast tomography (LabDCT) produces three-dimensional (3D) maps of crystallographic orientation. The non-destructive nature of the technique affords the key benefit of full 3D context of these, and other, in situ measur

A 270 spot-analysis study was conducted across a large (ca. 1200 μm x 1200 μm) chip of Geo2 olivine from a commercially available GEO Mk2 block (P and H Developments 2016) which revealed a 8.7% relative range in FeO abundance. Interleaved and overl
