内容記述 | A new angrite-type achondrite was discovered at a new site of meteorite concentrations in Antarctica by the Japanese expedition party in December 1988. Antarctic meteorite Asuka-881371 (previously Asuka-9) is an angrite-type achondrite, which is a rounded individual stone, almost completely covered with a dull-black fusion crust. Pale green, relatively large porphyritic olivine crystals can be seen on the exposed face of the interior. Asuka-881371 is an unbrecciated, igneous rock with typically ophitic (doleritic) texture, consisting mainly of olivine, pyroxene (fassaite) and plagioclase with spinel. From its texture, mineral assemblages and chemical composition, Asuka-881371 is identified and classified as an angrite. However, based on several characteristics, especially bulk chemical composition, Asuka-881371 is different from Angra dos Reis, LEW86010 and LEW87051 angrites which are the three previously known angrites collected from non-Antarctic and Antarctic regions. | |||||||
