Chondrites consist of three major components: refractory inclusions (Ca, Al‐rich inclusions
[CAI s] and amoeboid olivine aggregates), chondrules, and matrix. Here, I summarize recent …

Metasomatism refers to the process during which a pre-existing rock undergoes
compositional and mineralogical transformations associated with chemical reactions …

Calcium‐and aluminum‐rich inclusions (CAIs), chondrules, dark inclusions and matrices in
certain CV3 carbonaceous chondrites appear to have been modified by different degrees of …

The oxidized CV3 chondrites can be divided into two major subgroups or lithologies, Bali‐
like (CV3oxB) and Allende‐like (CV3oxA), in which chondrules, calcium‐aluminum‐rich …

1. INTRODUCTION may be that much of the early solar nebula consisted of completely
vaporized primordial material (> 1800 K) that cooled monotonically (Cameron, 1963; Kurat …

Vapor pressures of Ca (OH) 2 (g) and Al (OH) 3 (g) were measured using the transpiration
technique, employing the reactions CaO (s)+ H 2 O (g)⇌ Ca (OH) 2 (g); 2CaAl 2 O 4 (s)+ H 2 …

Mineralogic, petrologic, and isotopic studies of chondritic meteorites have revealed a
significant body of evidence of metasomatic processes during the earliest stages of Solar …

We report on the mineralogy, petrography, and O and Al-Mg isotopic systematics of
secondary mineralization in the metasomatically altered igneous Ca, Al-rich inclusions …

We have studied an Allende dark inclusion by optical microscopy, scanning electron
microscopy, electron microprobe analysis and transmission electron microscopy. The …

We have characterized Ca‐Fe‐rich silicates (salite‐hedenbergite pyroxenes (Fs10–50Wo45–
50), andradite (Ca3Fe2Si3O12), kirschsteinite (CaFeSiO4), and wollastonite (Ca3Si3O9)) in …
