Abstract LA-ICP-MS and LA-MC-ICP-MS have been the techniques of choice for achieving
accurate and precise element content and isotopic ratio, the state-of-the-art technique …

Some years ago, the consensus was that asteroid (16) Psyche was almost entirely metal.
New data on density, radar properties, and spectral signatures indicate that the asteroid is …

Plots such as ε54Cr vs. ε50Ti and ε54Cr vs. Δ17O reveal a fundamental dichotomy among
planetary materials. The “carbonaceous” chondrites, by virtue of high ε50Ti and high ε62Ni …

Classification of meteorites is largely based on their mineralogical and petrographic
characteristics and their whole-rock chemical and O-isotopic compositions. According to the …

The main belt is believed to have originally contained an Earth mass or more of material,
enough to allow the asteroids to accrete on relatively short timescales. The present-day …

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 …

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 …

In the absence of a firm link between individual meteorites and their asteroidal parent
bodies, asteroids are typically characterized only by their light reflection properties, and …

We review the crystallization of the iron meteorite chemical groups, the thermal history of the
irons as revealed by the metallographic cooling rates, the ages of the iron meteorites and …

The accuracy of radioisotopic ages is, at present, limited by the accuracy of radioactive
decay constants. A literature survey reveals that decay constants used in geo-and …
