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.

1、南极陨石藏品鉴定与分类：已鉴定出约300个新的南极陨石标本，并划分为各类陨石。日本自1969年收集的南极陨石藏品已分类为24块铁陨石、6块石铁陨石、5309块球粒陨石、158块无球粒陨石、60块碳质球粒陨石和61块未加工的球粒陨石，这些都包括以前和初步分类的标本。 2．月球陨石鉴定：在大和79号和82号藏品中发现了两块新的月球陨石。 Yamato-793274 (8g) 和 Yamato-82193 (27g) 源自月球。日本有4块月球陨石，预计是在一颗巨型陨石降落到月球时从月球表面的背面产生的。3．寻找新型橄榄石：第一个含有辉石的橄榄石是在 Yamato-84 陨石系列中发现的。这个标本可能是新型陨石，但我们需要更多的检查。
