The CM chondrites are samples of primitive water-rich asteroids formed during the early
solar system. They record significant interaction between liquid water and silicate rock …

Major advances in deciphering the record of nebula processes in chondrites can be
attributed to analytical improvements that allow coordinated isotopic and mineralogical …

We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

Chondrule-like objects and Ca-Al-rich inclusions (CAIs) are discovered in the retuned
samples from asteroid Ryugu. Here we report results of oxygen isotope, mineralogical, and …

A systematic survey of 57 different paragenetic modes distributed among 5659 mineral
species reveals patterns in the diversity and distribution of minerals related to their evolving …

Mineralogical observations, chemical and oxygen–isotope compositions, absolute 207Pb–
206Pb ages and short-lived isotope systematics (7Be–7Li, 10Be–10B, 26Al–26Mg, 36Cl …

About 435 mineral species have been identified in meteorites including native elements,
metals and metallic alloys, carbides, nitrides and oxynitrides, phosphides, silicides, sulfides …

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 …

We have studied porphyritic olivine-rich chondrules of the carbonaceous chondrite Kaba
(CV3) by combined high-resolution X-ray mapping, quantitative electron microprobe …

The abundant phyllosilicate and carbonate minerals characterizing most of the returned
particles from asteroid Ryugu suggest a history of extensive aqueous alteration on its parent …
