This study examines the history of the paradigm concerning a lunar (or solar-systemwide)
terminal cataclysm (also called “Late Heavy Bombardment” or LHB), a putative, brief spikein …

The breakup of the L-chondrite parent body (LCPB) in the mid-Ordovician is the largest
documented asteroid breakup event during the past 3 Gyr. It affected Earth by a dramatic …

We performed the first measurements of hydrogen isotopic composition and water content in
nominally anhydrous minerals collected by the Hayabusa mission from the S-type asteroid …

The thermal history of asteroids is recorded by the radioisotopic ages of meteorites that
derive from them. Radioisotopic ages may date a number of events, such as the cooling of a …

We conducted a petrologic study of apatite within one LL chondrite, six R chondrites, and six
CK chondrites. These data were combined with previously published apatite data from a …

Shock‐induced melting textures and high‐pressure polymorphs in 178 ordinary chondrites
of all chemical groups and petrologic types were investigated. The shock‐induced melting …

Abstract Northwest Africa (NWA) 11042, originally classified as a primitive achondrite with
no chondritic relicts, is rather a unique L‐melt rock. It is a severely shocked, igneous …

The disruption of the L chondrite parent body (LCPB) at~ 470 Ma is currently the best‐
documented catastrophic celestial impact event, based on the large number of L chondritic …

The collision history of asteroids is an important archive of inner Solar System evolution.
Evidence for these collisions is brought to Earth by meteorites. However, as meteorites often …

Apatite is an important petrogenetic indicator in extraterrestrial materials. Here, we report the
mineralogical features of apatite and associated phases in three brachinites Northwest …
