YARATKULOVO – A NEW H-CHONDRITE IN THE URALS: MINERALOGICAL DATA [PDF]
Минералогия, 2017 The Yaratkulovo meteorite was found in 2016 in the Argayash district of the Chelyabinsk region. It is a «chondrite breccia», in which the light coarse-grained fragments (primary chondrite) occur in the dark fine-grained matrix (impact assemblages ...

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 ...

Exploring Exogenic Sources for the Olivine on Asteroid (4) Vesta
, 2015 The detection of olivine on Vesta is interesting because it may provide critical insights into planetary differentiation early in our Solar System's history.

Eos, Transactions American Geophysical Union, 1971 Because of their numerical dominance among meteorite falls, their great age, and their primitive (i.e., quasisolar) compositions, the chondrites are central to discussions of the origin and early history of the solar system. The bibliography includes most American contributions m this field from 1967 to 1970, and this report attempts to summarize our ...

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 ...
