Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Petrography and mineral chemistry of Northeast Africa 053—A remnant of Martian crystal mush

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In Earth's igneous systems, crystal mushes, crystal‐rich frameworks permeated by silicate melt, represent a common and fundamental stage in the evolution of magma bodies. However, whether crystal mushes occur within Martian igneous systems and play a comparable role is unknown. Here, we present a comprehensive petrography and mineral chemistry

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Theologies of Mind: Eriugena and Pratyabhijñā Śaivism

open access: yesModern Theology, EarlyView.
Abstract Though Eriugena's affinities with several Hindu traditions are clear, this article offers to my knowledge the first detailed discussion of Eriugena's theology in relation to any Indic theological school, here, the nondualist Śaiva tradition known as the Pratyabhijñā (“Recognition”) lineage.
