Short-lived chlorine-36 in a Ca- and Al-rich inclusion from the Ningqiang carbonaceous chondrite.

Excesses of sulfur-36 in sodalite, a chlorine-rich mineral, in a calcium- and aluminum-rich inclusion from the Ningqiang carbonaceous chondrite linearly correlate with chorine/sulfur ratios, providing direct evidence for the presence of short-lived chlorine-36 (with a half-life of 0.3 million years) in the early solar system. The best inferred (36Cl/35Cl)o ratios of the sodalite are approximate...

A Metamorphosed Olivine-rich Aggregate in the Cv3 Carbonaceous Chondrite

A metamorphosed olivine-rich aggregate was found in the least metamorphosed CV3 Y-86009. Although such aggregates were observed in CV3 Mokoia and Vigarano, and CO (CM) Acfer 094 [1-3], their precursors and formation mechanism have not been fully understood. Here, we report mineralogical observations of an olivine-rich aggregate in the Y-86009. The olivine-rich aggregate is embedded in matrix. I...

Phosphoran-olivine in Opaque Assemblages of the Ningqiang Carbonaceous Chondrite: Implication to Their Precursors

Introduction: Opaque assemblages (OAs) are very complex objects in CV3 chondrites. They consist of Ni-rich metal, Fe-oxides, sulfides, phosphates, silicates, refractory Pt-group element metals (PGMs) and their oxides. OAs occur in CAIs, chondrules, and matrix of CV3 chondrites [1,2]. Some of the phases are refractory and others are volatile. They can consist of highly reduced or highly oxidized...

Al-mg Dating of Ca-al-rich Inclusions in Acfer 094 Chondrite

Introduction: Acfer 094 is one of the most primitive chondrites, which appears to have escaped thermal metamorphism above 300°C [1] and can potentially provide important clues to primary, undisturbed by parent body processes, abundances of short-lived ra-dionuclides in its components. Krot et al. [2] have recently described mineralogy and petrography of the Al-rich chondrules and refractory inc...
