Trace element composition of troilite, iron and iron-nickel metall from meteorite Chelyabinsk
Литосфера, 2015 We studied the contents of trace elements in troilite, iron and in iron-nickel metal from meteorite Chelyabinsk by means of LA-ICP-MS. The features of the distribution of siderophile and chalcophile elements in sulfide and metallic phase in gray and ...

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 ...

Northwest Africa 11024—A heated and dehydrated unique carbonaceous (CM) chondrite
Meteoritics and Planetary Science, 2018 Based on the high abundance of fine‐grained material and its dark appearance, NWA 11024 was recognized as a CM chondrite, which is also confirmed by oxygen isotope measurements.

Discovery of the Fe-analogue of akimotoite in the shocked Suizhou L6 chondrite
Scientific Reports, 2017 We report the first natural occurrence of the Fe-analogue of akimotoite, ilmenite-structured MgSiO3, a missing phase among the predicted high-pressure polymorphs of Fe-pyroxene, with the composition (Fe2+0.48Mg0.37Ca0.04Na0.04Mn2+0.03Al0.03Cr3+0.01)Σ=1 ...

Study of the Extraterrestrial Materials at Antarctica, III : On the Yamato Meteorites
Antarctic Record, 1973 Antarctica is thought to be the most suitable place for searching extraterrestrial materials. Since 1965, we have been studying microtektite and cosmic dust in Antarctica.

The Compositional Structure of the Asteroid Belt
, 2015 The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measurement of physical characterization.

Early aqueous activity on the ordinary and carbonaceous chondrite parent bodies recorded by fayalite
Nature Communications, 2015 Chronology of aqueous activity on chondrite parent bodies constrains their accretion times and thermal histories. Radiometric 53Mn–53Cr dating has been successfully applied to aqueously formed carbonates in CM carbonaceous chondrites.
