Since 1994, the Rumuruti (R) chondrites have been recognized as a new, well-established
chondrite group differing from carbonaceous, ordinary, and enstatite chondrites. The first R …

The seven nakhlite meteorites are augite-rich igneous rocks that formed in flows or shallow
intrusions of basaltic magma on Mars. They consist of euhedral to subhedral crystals of …

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

It is assumed in models of terrestrial planet formation that colliding bodies simply merge.
From this the dynamical and chemical properties (and habitability) of finished planets have …

The goal of classifying shock metamorphic features in meteorites is to estimate the
corresponding shock pressure conditions. However, the temperature variability of shock …

Metal‐troilite textures are examined in metamorphosed and impact‐affected ordinary
chondrites to examine the response of these phases to rapid changes in temperature …

Northwest Africa (NWA) 869 consists of thousands of individual stones with an estimated
total weight of about 7 metric tons. It is an L3–6 chondrite and probably represents the …

This paper explores impact melt and vapor generation for a variety of impact speeds and
materials using the shock physics code CTH. The study first compares the results of two …

Portales Valley (PV) is an unusual metal‐veined meteorite that has been classified as an H6
chondrite. It has been regarded either as an annealed impact melt breccia, as a primitive …

Ordinary chondrites originate from S-type asteroids. These meteorites can be used for
laboratory studies that further our understanding of the geological conditions on asteroids …
