Potential Mercurian Analogues: Aubrite and Enstatite Chondrite Impact Melt Meteorites [PDF]

, 2018
The MESSENGER (MErcury Surface Space ENvironment GEochemistry and Ranging Spacecraft) mission provided new data that have helped us better constrain the surficial mineralogy and composition of Mercury. Mercury has an extremely low oxygen fugacity (f O2) (

Replication Data for: Chromium Stable Isotope Panorama of Chondrites and Implications for Earth Early Accretion

: We investigated the stable isotope fractionation of chromium (Cr) for a panorama of chondrites, including EH and EL enstatite chondrites and their chondrules and different phases (by acid leaching).

In Situ Determination of Siderophile Trace Elements in Metals and Sulfides in Enstatite Achondrites [PDF]

, 2010
Enstatite meteorites are identified by their extremely reduced mineralogy (1) and similar oxygen isotope composition (2). The enstatite meteorite clan incorporates both EH and EL chondrites, as well as a wide variety of enstatite achondrites, such as ...

Métamorphisme d'une chondrite à enstatite nommée Indarch : implication sur les phénomènes de différenciation planétaire. Application à la Terre

, 2009
Enstatite chondrites share a common oxygen reservoir with Earth and Moon. This suggests that these meteorites may have participated to the building of the planet Earth.

Unequilibrated assemblages of sulphide, metal and oxide in the fusion crusts of the enstatite chondrite meteorites

, 1999
The fusion crusts of meteorites form due to heating during atmospheric entry and have mineralogies which are strongly influenced by changes in oxidation state.

Metamorphism of an enstatite chondrite named Indarch : implications of planetary differentiation processes. Application to the Earth

, 2009
Les chondrites à enstatite partagent un réservoir commun de l’isotope de l’oxygène avec la Terre et la Lune. Cette caractéristique soulève la question d’une possible participation de ce type de météorites à la construction de la Terre. Egalement, l’étude

FeO-rich silicates in the Sahara 97159 (EH3) enstatite chondrite: Mineralogy, oxygen isotopic compositions, and origin

, 2003
We report the mineralogy and oxygen isotopic compositions of FeO-rich silicates in the Sahara 97159 EH3 chondrite. This component is referred to as FeO-rich because it contains substantially more FeO than the characteristic FeO-poor silicates in the ...
