Investigation and reclassification of four mesosiderites—Implications for their formation

Meteoritics &Planetary Science, EarlyView.
Abstract Mesosiderites are rare, differentiated meteorites, so‐called stony‐iron meteorites—they are impact breccias composed of an unusual mix of crustal basalt and pyroxenite, core‐derived metal, but no mantle materials. This odd mixture makes their origin enigmatic and has inspired many different formation theories over the last several decades ...

Shock-compressed MgSiO_3 glass, enstatite, olivine, and quartz: Optical emission, temperatures, and melting [PDF]

, 2004
Optical emission of MgSiO_3 glass, enstatite, olivine, and quartz under shock wave compression was investigated with optical pyrometry at discrete wavelengths ranging from visible to near infrared.

Nanoscale Voltage Enhancement at Cathode Interfaces in Li-ion Batteries

, 2017
Interfaces are ubiquitous in Li-ion battery electrodes, occurring across compositional gradients, regions of multiphase intergrowths, and between electrodes and solid electrolyte interphases or protective coatings. However, the impact of these interfaces

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

Meteoritics &Planetary Science, EarlyView.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Cosmic ray exposure and gas retention ages of the shocked angrite Northwest Africa 7203: Implications for a collisional history of angrites' parent body

Meteoritics &Planetary Science, EarlyView.
Abstract Angrites and eucrites are among the oldest basaltic rocks in the solar system. However, the shock histories of these meteorite groups differ markedly, as most angrites show little to no evidence of shock metamorphism. While some angrites exhibit weak wavy extinction in olivine, indicative of low‐level shock, only two—Northwest Africa (NWA ...

The 10 micron spectral structure in comets [PDF]

The 10 micron spectra of comets Halley (1982i), Wilson (1986l), Kohoutek (1973f) and Bradfield (1987s) are presented and compared. The silicate emission profiles of Halley and Bradfield are seen to be remarkably similar in that both contain a sharp break

Hawaiian beaches as natural analogues for enhanced silicate weathering of olivine

Environmental Research Letters
Silicate weathering induces atmospheric CO _2 sequestration through alkalinity release, which is Earth’s prime mechanism for regulating the climate. Marine enhanced rock weathering (mERW) seeks to accelerate this process by distributing fast-weathering ...

3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159

Meteoritics &Planetary Science, EarlyView.
Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

The fall of the Haag (LL4‐6) chondrite breccia—Just 8 years after the nearby fall Stubenberg (LL6)

Meteoritics &Planetary Science, EarlyView.
Abstract On October 24, 2024, an impressive fireball was visible over Austria. After the possible strewn field was calculated, the first sample of the Haag meteorite, with a mass of 8.76 g, was discovered on November 2, 2024, 8 days after the fireball event. Four more samples were found afterward putting the total sample mass at about 151 g.
