Variations in bulk Mg/Si ratios in the various groups of chondritic meteorites indicate that Mg/Si fractionation occurred in the primitive solar nebula. Enstatite (MgSiO3) evaporates incongruently forming forsterite (Mg2SiO4) ...

Incongruent evaporation experiments on troilite (FeS) were carried out under H2-rich conditions at total pressure 1.0-10-6 atm (800-970°C) to elucidate the kinetics of incongruent evaporation of troilite in the primordial ...

We performed a systematic high-precision secondary ion mass spectrometry 26Al-26Mg isotopic study for 11 ferromagnesian chondrules from the highly unequilibrated ordinary chondrite Bishunpur (LL3.1). The chondrules are ...
