The howardite, eucrite and diogenite (HED) clan of meteorites are ultramafic and mafic
igneous rocks and impact-engendered fragmental debris derived from a thoroughly …

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

The 182Hf–182W systematics of meteoritic and planetary samples provide firm constraints
on the chronology of the accretion and earliest evolution of asteroids and terrestrial planets …

Available evidence strongly suggests that the HED (howardite, eucrite, diogenite) meteorites
are samples of asteroid 4 Vesta. Abundances of the moderately siderophile elements (Ni …

Abstract Howardite-eucrite-diogenite (HED) meteorites, thought to be derived from 4 Vesta,
provide the best sampling available for any differentiated asteroid. However, deviations in …

Meteorite breccias provide information about impact processes on planetary bodies, their
collisional evolution and structure. Fragmental and regolith breccias are abundant in both …

Determining the origin of water and the timing of its accretion within the inner solar system is
important for understanding the dynamics of planet formation. The timing of water accretion …

A finite element code has been developed to model the thermal history of Asteroid 4 Vesta.
This is the first attempt to model the thermal history of a differentiated asteroid through core …

Aluminum-magnesium isotopic analysis of plagioclase in the eucrite Piplia Kalan, with
27Al/24Mg ratio between 2000 to 7000, reveals the presence of excess magnesium-26 …

The large-scale compositional structures of planets are primarily established during early
global differentiation. Advances in analytical geochemistry, the increasing diversity of …
