Trace element composition of silicate minerals from Kunashak Meteorite (L6)

Записки Горного института
Major (EPMA) and trace (SIMS) element geochemistry in the silicate minerals (olivine, pyroxene and plagioclase) of Kunashak equilibrated ordinary chondrite (L6) is described. No variations in the major element concentrations of the silicate minerals have

Synthesis of Si-Fe Chondrule-like Dust Analogues in RF Discharge Plasmas

Applied Sciences
Chondrules are tiny particles that occur in stony meteorites and are considered as the building blocks of early asteroids and planets. It is believed that they were formed by the fast heating of the dust in the solar nebula.

Late Pebble Accretion of Comet 81P/Wild 2 Nucleus: Evidence from a Plagioclase-bearing Chondrule Fragment, Pyxie

The Astrophysical Journal
Comet 81P/Wild 2 is a ∼4.5 km-sized primordial object that almost has not been modified by internal heating by ^26 Al decay. Its nucleus could have been formed by hierarchical agglomeration or gravitational collapse of pebble swarms concentrated by ...
