Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments
Journal of Raman Spectroscopy, EarlyView.Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Meteorites: Messengers from the Early Solar System
CHIMIA, 2010 Meteorites are fragments from solar system bodies, dominantly asteroids. A small fraction is derived from the Moon and from Mars. These rocks tell a rich history of the early solar system and range from solids little changed since the earliest ...

A comprehensive study of noble gases and nitrogen in Hypatia, a diamond-rich pebble from SW Egypt [PDF]
, 2015 This is a follow-up study of a work by Kramers et al. (2013) on an unusual diamond-rich rock found in the SW side of the Libyan Desert Glass strewn field. This pebble, called Hypatia, is composed of almost pure carbon.

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen
Physik in unserer Zeit, EarlyView.Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.

Young asteroidal fluid activity revealed by absolute age from apatite in carbonaceous chondrite
Nature Communications, 2016 Chondritic meteorites formed in the early solar system and may tell us about primary processes at that time. Here, Zhang et al. report an absolute 207Pb/206Pb isochron age (4,450±50 Ma) of apatite from a carbonaceous chondrite constraining timing of ...
