Petrology and geochemistry of nakhlite MIL 03346: A new Martian meteorite from Antarctica
MIL 03346 is a newly discovered meteorite from Miller Range in Antarctica, which belongs to the nakhlite group of Martian meteorites [1]. It is an unbrecciated, mediumgrained olivinebearing clinopyroxenite with a cumulate texture, similar to the 6 other previously known nakhlites. This is only the 2 nakhlite in Antarctic collections, the other being Yamato 000593 and its pairs. The Meteorite Wo...
متن کاملTRACE ELEMENT AND εNd SYSTEMATICS IN THE NAKHLITE MIL 03346 AND THE ORTHOPYROXENITE ALH 84001: IMPLICATIONS FOR THE MARTIAN MANTLE
Introduction: MIL 03346 is a newly discovered clinopyroxenite belonging to the nakhlite class of SNC (martian) meteorites [1]. Although the petrographic and geochemical characteristics of MIL 03346 are broadly similar to those of previously known nakhlites, there are also some differences. In particular, it has the highest abundance of glassy mesostasis among the nakhlites, possibly indicative ...
متن کاملOxygen Fugacity of the Martian Mantle from Pyroxene/melt Partitoning of Ree
Introduction: This study is part of an ongoing effort [1-3] to calibrate the pyroxene/melt REE oxybarometer for conditions relevant to the martian meteorites. Redox variations have been reported among the shergottites [4-6]. Wadhwa [4] used the Eu and Gd augite/melt partitioning experiments of [7], designed for the LEW86010 angrite, to infer a range of fo2 for the shergottites. [5,6] inferred f...
