Review of asteroid, meteor, and meteorite‐type links

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Microfaults: Abundant shear deformation and frictional melting in chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 858-868, April 2025.
Abstract The majority of ordinary chondrite (OC) meteorites record some amount of textural evidence for impact‐induced deformation. Melt veins in some shocked samples have been compared to terrestrial impact‐related pseudotachylites, which form by frictional melting of host rock.

How Cratonic Roots Survive With Weak Mid‐Lithosphere Discontinuities

open access: yesGeophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract The stability of cratons has long been attributed to their neutral buoyancy and strong roots. However, recent seismic studies have revealed widespread mid‐lithospheric discontinuities (MLDs) within cratonic roots. Previous studies, based on geophysical and xenolith evidence, mainly suggest that MLDs are formed through metamorphic processes and
