Substitution of Fe3+ into anorthite in oxidized, Al‐deficient ferrobasaltic systems with implications for the petrogenesis of angrite meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Angrite meteorites are critically silica‐undersaturated igneous rocks with high Ca/Al and Fe/Mg, along with depletion in volatile lithophile elements Na and K such that they crystallize anorthite along with olivine and calcic pyroxene. The anorthite in angrites contains substantial Fe, and in NWA 1670 and NWA 1296, it is present at major ...

Terrestrial ages of Antarctic meteorites: Implications for concentration mechanisms [PDF]

Antarctic meteorites differ from meteorites fallen in other places in their mean terrestrial ages. Boeckl estimated the terrestrial half-life for the disintegration of stone meteorites by weathering under the climatic conditions of the Western United ...

Nature's Starships II: Simulating the Synthesis of Amino Acids in Meteorite Parent Bodies

, 2015
Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of ...

The Future of Food Processing—A Food Science and Technology Perspective. Proceedings of a Roundtable Event

Nutrition Bulletin, EarlyView.
ABSTRACT Rising interest in the links between processed food consumption and poor health outcomes often overlooks the perspectives of those working in food technology and innovation. To address this, a virtual roundtable was held in October 2024 to provide a setting for a technical discussion among those working in food processing, technology and ...

Data-Driven UPLC-Orbitrap MS Analysis in Astrochemistry

Life, 2019
Meteorites have been found to be rich and highly diverse in organic compounds. Next to previous direct infusion high resolution mass spectrometry experiments (DI-HR-MS), we present here data-driven strategies to evaluate UPLC-Orbitrap MS analyses.

Fluid evolution in CM carbonaceous chondrites tracked through the oxygen isotopic compositions of carbonates [PDF]

, 2017
The oxygen isotopic compositions of calcite grains in four CM carbonaceous chondrites have been determined by NanoSIMS, and results reveal that aqueous solutions evolved in a similar manner between parent body regions with different intensities of ...

Multi-satellite Universat-SOCRAT mission for monitoring technogenic and natural hazards

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019
The natural and “man-made” space environment generates serious risks for the implementation of space missions, both automatic and human. The main natural and technogenic risk factors that limit or pose a threat to the implementation of space-based ...

Classification of stony meteorites and chondrules – the case of meteorite Jesenice

Geologija, 2012
In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites.

Relationships among basaltic lunar meteorites [PDF]

During the past two years four meteorites of dominantly mare basalt composition were identified in the Japanese and US Antarctic collections. Basalts represent a much higher proportion of the lunar meteorites than is expected from photogeologic mapping ...
