Synopsis: The oxygen fugacity of the basaltic martian meteorites has been calculated from thermodynamic models involving spinel-ilmenite equilibria. The wide range of estimates, from near the IW buffer to near QFM, may be explained by mixing of mantlederived melts with oxidized material in the martian crust. Possible oxidized crustal end-members are considered. Analytical Method and Results: Sp...

To tackle the scale-up of Chemical Looping Processes, production efficient and affordable oxygen carriers appears paramount importance. Ilmenite is an ore-derived carrier which can be considered surely abundant cheap. The preparation characterization its reactivity are presented in following paper. paper describes briefly performance ilmenite relating it to other carriers, thermodynamic propert...

In this paper, our purpose is to calculate photon-matter interaction parameters of Ni-based alloys, Inconel-617 and Incoloy-800HT, which are the main candidates for high-temperature applications such as spacecraft, gas turbines, nuclear reactors rocket motors. The radiation attenuation buildup factors were obtained in a wide energy range by using Phy-X/PSD EpiXS softwares determine protection c...

In this work, the geochemical characterization of olivine-phyric Martian shergottite LAR 12095 was performed by using two complementary analytical techniques: micro-Raman and micro-energy dispersive X-ray fluorescence spectroscopies. Thanks to methodology, olivine, pyroxene, ilmenite were detected as primary minerals from Mars. Maskelynite, hematite, anatase, chromite, merrillite, oxidized mack...

the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...

The mineral ilmenite is analysed by LA-ICP-MS for elemental and U–Pb isotopic compositions. A methodology presented accurate results using the rutile ages basaltic reference materials major trace elements.
