Abstract— In the Saint Aubin octahedrite, chromite crystals of up to 3 cm occur enclosed in the metal phase. They are twinned along [111] according to the spinel law and display pseudohexagonal shapes in cross‐sections. The crystals are homogeneous and exhibit compositions close to pure chromite endmember. Vanadium is the only additional element observed in appreciable amounts of up to 0.73 wt%. Chromite in the Saint Aubin meteorite crystallized from liquids with very low amounts of Cr and O… 
Zincian chromite inclusions in diamonds: Possibility of deep recycling origin
It was reported by Meyer and Boyd (1972) that zincian chromite, having 2 wt% to 3 wt% ZnO and high (>0.9) Cr# (= Cr/(Cr + Al) atomic ratio), appears as inclusions in diamonds obtained from
Noble gas content and isotope abundances in phases of the Saint‐Aubin (UNGR) iron meteorite
Abstract— We analyzed the noble gas isotopes in the Fe‐Ni metal and inclusions of the Saint‐Aubin iron meteorite, utilizing the stepwise heating technique to separate the various components of noble
Isotopic evidence for pallasite formation by impact mixing of olivine and metal during the first 10 million years of the Solar System
Pallasites are mixtures of core and mantle material that may have originated from the core-mantle boundary of a differentiated body. However, recent studies have introduced the possibility that
From 2D to 3D Characterization of Materials Subjected to Extreme Pressure and Temperature Conditions
Planetesimal were the first planetary objects to form in the solar system, which later grew to make the proto-planets. Most of these bodies were differentiated as a result of internal heating.
A large planetary body inferred from diamond inclusions in a ureilite meteorite
Inclusions within diamonds from a ureilite meteorite are analysed and it is found that they must have formed at above 20 GPa suggesting the parent body was Mercury- to Mars-sized.
Combining IR and X‐ray microtomography data sets: Application to Itokawa particles and to Paris meteorite
In the near future, a new generation of sample return missions (Hayabusa2, OSIRIS‐REx, MMX, etc.) will collect samples from small solar system bodies. To maximize the scientific outcome of laboratory
Les inclusions magmatiques : des cinétiques de croissance cristalline à la formation des corps planétaires
Decrypter les mecanismes et cinetiques de croissance et dissolution des mineraux dans les liquides silicates est indispensable a la comprehension des processus magmatiques fondamentaux. La migration


The Sychevka IIIAB iron meteorite: A new find from Russia
— Sychevka is a relatively unweathered 65-kg iron meteorite that was found in Russia in 1988. The microstructure, mineralogy and bulk composition of Sychevka as revealed by optical microscopy,
The Bocaiuva iron contains 10 to 15% by volume of silicate inclusions which are surrounded by kamacite (6.5 wt % Ni). The metal shows a Widmanstatten pattern in metal areas devoid of silicates;
Natural occurrence and synthesis of two new postspinel polymorphs of chromite
A high-pressure polymorph of chromite, the first natural sample with the calcium ferrite structure, has been discovered in the shock veins of the Suizhou meteorite. Synchrotron x-ray diffraction
The Landes silicate-bearing octahedrite is a new find from Grant County, West Virginia. Minerals and their compositions are very similar to those in Odessa-type silicate inclusions. The angular
Little Minnie Creek, an L4(S2) ordinary chondritic meteorite from Western Australia
The Little Minnie Creek meteorite, weighing 357 g, was found in 1997 at co-ordinates 24° 08' 16.9" S, 115° 52' 17.5" E in the Gascoyne District of Western Australia. Equilibrated ferromagnesian
