Martian meteorites as windows into planetary volcanism: insights from olivine-phyric shergottite meteorites
… solely on single meteorites. One group of shergottite meteorites, comprising approximately 20 samples with crystallisation ages from 2.4 to 0.35 Ga, share similar geochemical characteristics and ejection ages of 1.1 Ma, and are suggested to have originated from a common long-lived volcanic …

A comparison of iddingsite alteration in two terrestrial basalts and the ALHA 77005 martian meteorite using Raman spectroscopy and electron microprobe analyses.
… the ALHA 77005 martian meteorite: a lherzolitic shergottite). Short laser Raman spectroscopic traverses: hundreds of μm long) across olivine alteration fronts provide information about changes in the mineral assemblage with alteration. Data from the Raman traverses are combined with data from …

Compositional Analysis of the Martian Meteorites Northwest Africa 6342 and Northwest Africa 10961
… type of meteorite that we have from Mars is the shergottite. This makes the study of shergottite samples invaluable to understanding the geological evolution of that planet. Electron microprobe analyses, bulk elemental composition calculation, and laser ablation-inductively coupled plasma-mass …

Phase equilibrium investigations of the Adirondack Class basalts from the Gusev plains, Gusev crater, Mars
… do they appear to be related to olivine-phyric shergottites or other SNC meteorites. The iron-rich Gusev basalts appear to have been crystallized from a less depleted mantle source than the magnesian olivine-phyric shergottite Yamoto 980459.

The role of C-O-H volatiles in the martian mantle and the production of the martian atmosphere.
… depolymerized partial melts similar to primitive shergottite Yamato 980459 (Y 980459) which are investigated in Chapter 3. Similar experiments are performed on a synthetic starting material based on Y 980459. Despite large differences in FeO* (Fe2O3+FeO) and MgO contents, the CO2 solubilities in Y …

Light as a universal tool : Microcapsule sizing by elastic light scattering and mineral investigation by in situ Raman spectroscopy
… phase in the picritic (olivin-phyric) shergottite NWA 1068 as well as reduced carbon (e.g. graphite) and anatase in the shergottite Say al Uhaymir 060 are new findings for this class of meteorites. A detailed description of the proposed designs for MIRAS, with the compo-nents used for …
