Studies on Taxonomy and Catalog of Meteorites Collected from Antarctica

1.南极陨石收藏鉴定与分类：目前已鉴定出约300个新的南极陨石标本，并将其分类为不同类型的陨石。日本自1969年以来收集的南极陨石包括24个铁质陨石、6个石质陨石、5309个球粒陨石、158个无球粒陨石、60个碳质球粒陨石和61个未加工的陨石，这些都是以前和初步分类的标本。陨石起源于月球：在Yamato-79和82系列中发现了两块新的月球陨石。大和-793274(8克)和大和-82193(27克)是月球的起源。日本有4颗月球陨石，预计它们是在一颗巨大的陨石降落到月球时从月球表面的远侧起源的。发现新类型的辉石：在Yamato-84陨石收藏中发现了第一个含有辉石的辉石。这个标本可能是新类型的陨石，但我们还需要更多的检验。

1. Identification and classification of the Antarctic meteorite collections:About 300 new specimens of the Antarctic meteorites have been identified and classified to various types of meteorite. Japanese collections of Antarctic meteorites collected since 1969 season have been classified as 24 Irons, 6 Stony-Irons, 5309 Chondrites, 158 Achondrites, 60 Carbonaceous chondrites and 61 unprocessed one, those are included previously and preliminary classified specimens.2. Identification of meteorites originated from moon:Two new lunar meteorites were found in the yamato-79 and 82 collections. Yamato-793274 (8g) and Yamato-82193 (27g) are lunar origin. Japan has 4 lunar meteorites which are expected to originated from the far side of moon surface when a giant meteorite came down to the moon.3. Find new type pallasite:The first pallasite included pyroxene was found in the Yamato-84 meteorite collection. This specimen may new type of meteorite, but we need more examination.
