Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Earth's Lower Mantle Predominated by Ferric Iron‐Rich Bridgmanite Inferred From High Pressure Elasticity Measurements

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The absence of sound‐velocity data spanning the entire lower mantle pressures for (Fe, Al)‐bearing bridgmanite impedes direct comparisons with seismic wave observations, leaving the chemistry of the lower mantle unresolved. The present ultra‐high pressure sound‐velocity measurements of in situ synthesized (Fe, Al)‐bearing bridgmanite up to 130

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver
