International Workshop on Antarctic Meteorites [PDF]
, 1986 Topics addressed include: meteorite concentration mechanisms; meteorites and the Antarctic ice sheet; iron meteorites; iodine overabundance in meteorites; entrainment, transport, and concentration of meteorites in polar ice sheets; weathering of stony ...

Chondrule size averaging in two and three dimensions
Meteoritics &Planetary Science, EarlyView.Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...

Thermal history of an amoeboid olivine aggregate in the early solar nebula
Meteoritics &Planetary Science, EarlyView.Abstract Carbonaceous chondrites commonly contain amoeboid olivine aggregates (AOAs). Here, we investigated an AOA in the CR chondrite Y‐793261. This AOA contains an unstable assemblage of forsterite and quartz. We found a rare occurrence of enstatite and quantitatively discuss its formation process.

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.

Meteoritics &Planetary Science, EarlyView.Abstract Public fascination with impact craters often drives bold speculations, but rigorous verification is critical. In southeastern Bavaria, numerous depressions have been proposed to represent impact craters associated with a catastrophic event in Celtic times (between 900 BC and 600 BC)—the so called “Chiemgau Impact.” To date, the evidence ...

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 ...

Mysterious iodine-overabundance in Antarctic meteorites [PDF]
, 1986 Halogen as well as other trace element concentrations in meteorite finds can be influenced by alteration processes on the Earth's surface. The discovery of Antarctic meteorites offered the opportunity to study meteorites which were kept in one of the ...
