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

Hydrous Chondrites under Shock

The Astrophysical Journal
We examine the shock response of a chondrule-like multicomponent silicate melt enriched with 2 wt% H _2 O, representative of hydrous chondrites, using ab initio molecular dynamics.

Petrology of Chondrule Rims in Yamato-791498 and Asuka-881828, the Least-Altered CR Chondrites in the Japanese NIPR Collection [PDF]

CR chondrites are a group of car-bonaceous chondrites with well-preserved records of formation of their components in the solar nebula. The CR chondrites have undergone a wide range of aqueous alteration from nearly anhydrous (CR2.8 or CR3.0) to ...

Single chondrule K-Ar and Pb-Pb ages of Mexican ordinary chondrites as tracers of extended impact events

Revista Mexicana de Ciencias Geológicas, 2018
There is a good consensus about the age of the most primitive materials in the Solar System represented by carbonaceous chondrites. From these, a canonical age of the Solar System of 4567 Ma has been defined.
