Low‐temperature dissociation of zircon in highly alkaline conditions: A cautionary note for studies on natural glasses of debated origin

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Dissociated zircon is largely used as a robust indicator of glasses generated by impact cratering and airbursts. The reaction of zircon dissociation, i.e. ‘ZrSiO4 → ZrO2 + SiO2’, requires high temperatures (>1670°C) only reached by extreme geological processes. Using high‐temperature experiments, this study shows that zircon can dissociate and

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Pairing relationships of howardites, eucrites and diogenites (HED) from the Miller Range ice fields, Antarctica

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

Olivine–gabbroic shergottites: A petrogenetic link between poikilitic and gabbroic shergottites

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Shergottites span a textural, mineralogical, and geochemical range, and finding links between the various petrologic and geochemical groups is of great interest as it provides insight into the conditions of the Martian interior. Here, we compare the texture, mineralogy, mineral chemistry, and geochemistry of REE‐enriched intrusive shergottite ...

Observational constraints on entropic cosmology

open access: yesPhysics Letters B
In this work, we derive a generalized modified Friedmann equation based on an entropy-area relation that incorporates established modifications, such as volumetric, linear, and logarithmic terms, in addition to novel entropic modifications that might ...
