Microtextures and structures in metal–sulfide grains in NWA 869 meteorite and their relation to thermal history of L‐chondrite parent body

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.
Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

Textural and compositional characteristics of metallic spherules in impact melt from Monturaqui crater, Chile

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 646-662, March 2025.
Abstract Samples of impactite from the small (~350 m diameter) Monturaqui crater in northern Chile contain Fe‐Ni metallic spherules sourced from the iron meteorite impactor. Textural characterization and quantification were done using SEM and μCT data. Two textural types are distinguished, with different size distributions.

Impact crater lake evolution and concomitant hydrothermal mineralization recorded by the Wörnitzostheim drill core at the Ries impact structure, Germany

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 795-822, April 2025.
Abstract Impact‐generated hydrothermal systems and postimpact crater lake systems are well‐documented geological phenomena; however, evidence of hydrothermal venting into impact crater lake systems has rarely been reported. We investigated the well‐preserved contact between hydrothermally altered impact melt‐bearing breccia (outer/surficial suevite ...

Exploring the origins of magnetization within the Chicxulub crater upper peak ring

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 823-848, April 2025.
Abstract Large terrestrial impacts may produce vast subsurface hydrothermal systems, capable of generating conditions favorable to the origin of life. Modeling suggests that these systems may persist for >1 million years for basin‐sized craters; however, direct experimental constraints on hydrothermal system duration are needed.

Microfaults: Abundant shear deformation and frictional melting in chondrites

Meteoritics &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.
