VARIATIONS IN LIGHT LITHOPHILE ELEMENTS (Li, B, Be) AND LITHIUM ISOTOPES IN MARTIAN PYROXENES AND OLIVINES: ROLES OF DEGASSING AND DIFFUSION
Introduction: The zoning patterns of light lithophile elements (LLEs: Li, Be, B) in pyroxenes of some Martian meteorites have been used to suggest that the parent basalts were water-saturated, which exsolved and lost an aqueous phase through degassing and eruption, causing depletion in LLEs in the pyroxene rims [1]. In contrast, other investigators have suggested a diffusion controlled fraction...
متن کاملCOMPARING THE EFFECTS OF H2O, F, AND Cl ON NEAR-LIQUIDUS PHASE EQUILIBRIA OF A MODEL HIGH-Fe BASALT: IMPLICATIONS FOR VOLATILE INDUCED MANTLE
Introduction: Volatile species, such as H2O, CO2, F, and Cl, are important in the generation and differentiation of basaltic melts. On the Earth, dissolved H2O (or in certain circumstances CO2) is thought to be the dominant volatile in most basaltic magmas. Therefore, significant effort has been placed on understanding how water and CO2 affect basalt genesis and crystallization of terrestrial m...
متن کاملConstraints on the water, chlorine, and fluorine content of the Martian mantle
Previous estimates of the volatile contents of Martian basalts, and hence their source regions, ranged from nearly volatile-free through estimates similar to those found in terrestrial subduction zones. Here, we use the bulk chemistry of Martian meteorites, along with Martian apatite and amphibole chemistry, to constrain the volatile contents of the Martian interior. Our estimates show that the...
متن کاملA reduced organic carbon component in martian basalts.
The source and nature of carbon on Mars have been a subject of intense speculation. We report the results of confocal Raman imaging spectroscopy on 11 martian meteorites, spanning about 4.2 billion years of martian history. Ten of the meteorites contain abiotic macromolecular carbon (MMC) phases detected in association with small oxide grains included within high-temperature minerals. Polycycli...
متن کاملFormations of Martian Plagioclases and Flow Textures by Carbon- Dioxides-rich Gas and Fluids Compared with Natural Rocks and Artificial Products on the Earth
Introduction: Water liquid has been considered to be main fluid in cold Mars, though major sources of liquid water are not clearly found on Martian surfaces. Recently author (Y.M.) found carbon-bearing grains on plagioclase composition in druses of terrestrial volcanic basalts in Shimonoseki, Yamaguchi, Japan [1], where many scientists have been reported as normal “plagioclases” formed at hydro...
