Meteorite research is fundamental to our understanding of the origin and early history of the
Solar System. This book considers the mechanism and timing of core formation and basaltic …

The 182Hf-182W isotopic systematics of Ca-Al-rich inclusions (CAIs), metal-rich chondrites,
and iron meteorites were investigated to constrain the relative timing of accretion of their …

In ordinary chondrites (OCs), feldspar is present both in chondrules as a primary, igneous
phase, and as a secondary phase that results from crystallization of chondrule mesostasis …

The first cold plasma ICP-MS (inductively coupled plasma mass spectrometer) Fe isotope
study is described. Application of this technique to the analyses of Fe isotopes in a number …

Chondrules are the major high-temperature components of chondritic meteorites, which are
conventionally viewed as the samples from the very first generation of undifferentiated …

Chondrites are the largest group of meteorites. They can provide unique insights into the
origins and early evolution of our Solar System, and even into the relationships between our …

This paper reviews the evidence for short–lived radionuclides in the early Solar System and
critically evaluates models for their origin. Radionuclides with half–lives of less than 50 Myr …

One of the reasons noble gases make such good tracers of processes occurring in rocks is
their scarcity. Thus, a process that converts a small fraction of a relatively rare element into a …

The recently recovered paired Antarctic achondrites Graves Nunatak 06128 and 06129
(GRA) are meteorites that represent unique high-temperature asteroidal processes that are …

We summarize geochemical, astronomical, and theoretical constraints on the lifetime of the
protoplanetary disk. Absolute Pb-Pb-isotopic dating of CAIS in CV chondrites (4567.2±0.7 …
