Microfragments of the Saratov meteorite in the magnetic fraction of modern soils: search and identification

Записки Горного института
The paper addresses the problem of identifying microscopic traces of meteoritic material in soils more than 100 years after a fall. The area of the Saratov meteorite shower of October 6, 1918 was selected as the study site.

Yamato-694 Meteorite: Chemical Composition of Silicate Minerals and Petrographic Nature [PDF]

, 1979
P(論文)Yamato-694 meteorite collected near the Yamato Mountains in Antarctica in 1969 is an ordinary chondrite belonging to a high-iron group. Major chemical composition of its silicate minerals was determined by electron probe microanalysis.

The Dehydration of Serpentines and Extraction of Water

The Planetary Science Journal
Some groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

On Serine Octamer Substitution Reactions

Rapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.
ABSTRACT Rationale Monomeric amino acids substitute into the ionized serine octamer (Ser8), a magic number cluster that exhibits chiral behavior. Small biomolecules, such as amino acids (AA), substitute into the octamer enantioselectively, giving Ser7AAH+ and Ser6AA2H+ favoring clusters of all L‐ or all D‐chirality.

Impact-generated Porosity Gradients Controlled Fluid Flow and Aqueous Alteration on the CM Parent Body

The Planetary Science Journal
We investigated the relationship between microporosity, impact deformation, and aqueous alteration in the CM chondrite Murchison using high-resolution (1.86 μ m/voxel) X-ray computed tomography (XCT) combined with a pressurized xenon gas infiltration ...

Where the Mineral Kingdom Might Hide New Forms of Matter

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Mineralogy has traditionally classified matter primarily through local chemistry and diffraction symmetry. But some physically distinct states of matter differ neither principally in composition nor in obvious diffraction symmetry; they differ in how fluctuations behave over very large distances.

Volatile Element Depletion of Carbonaceous Chondrites—Insights from Mass-dependent Zinc, Cadmium, and Tellurium Isotope Variations

The Astrophysical Journal
The origin of volatile depletion in the solar system remains a topic of intense debate. To further inform our understanding of the mechanisms involved, this study characterized the mass-dependent Zn, Cd, and Te isotope compositions and concentrations of ...
