Large silica‐rich igneous‐textured inclusions in the Buzzard Coulee chondrite: Condensates, differentiates, or impact melts?

Clast-rich H-chondrite Impact Melts

Introduction: The H-chondrite parent asteroid provides the second-most abundant type of meteorites that currently reach Earth's surface [1]. These rocks recorded their parent asteroid's collisional history and melted H-chondrites chronicle the most severe cratering events. Samples and Methods: Seven samples of clast-rich impact melt rocks from the La Paz Icefield, Antarctica were analyzed in Pl...

Calcium isotopic ratios and rare earth element abundances in refractory inclusions from the Allende CV3 chondrite

Refractory inclusions in primitive meteorites are the oldest objects formed in the Solar System. They exhibit large massdependent isotopic effects in many elements, including Si, Mg and Ca, indicative of their complex origin. We report data for both mass-dependent (d) and mass-independent (e) Ca isotopic effects, and rare earth element (REE) abundances in six refractory inclusions from the Alle...
