Of 685 meteorites published in the Meteoritical Bulletin Database,there are 2 martian meteorites,2 eucrites,6 ureilites,5 mesosiderites,1 pallasite,1 iron,and 10 carbonaceous chondrites.

在正式公布的684块已分类陨石中，鉴定出2块火星陨石、2块灶神星陨石、6块橄辉无球粒陨石、5块中铁陨石、1块橄榄陨铁、1块铁陨石以及10块碳质球粒陨石等特殊样品，并对其中的部分样品开展了深入的研究。

But, for the Type 3 of unequilibrated meteorites, its difficult to determine their chemical groups exactly as the mineral composition varies in a large range and probably there is water in the meteorites.

对于岩石类型为第3类的非平衡陨石，由于矿物成分变化较大，并可能有水等易挥发成分的存在，其化学群的划分不易确定。

The chemical-petrographic types of these meteorites are presented below.Six are unequilibrated ordinary chondrites,including three H3 and three L3;92 meteorites are equilibrated ordinary chondrites,including 24 H-group(13 H4,10 H5,1 H6),64 L-group(2 L4,44 L5,18 L6) and 4 LL-group(3 LL4,1 LL5);the other two belong to stone-iron meteorites.In 6 unequilibrated ordinary chondrites,chondrules are well-shaped,and olivine and low-Ca pyroxene are commonly zoned and have wide ranges of composition.The olivine and low-Ca pyroxene in the other 92 equilibrated ordinary chondrites have similar composition,respectively,and to some degree it reflected thermodynamics equilibration in olivine and lowCa pyroxene.

并根据矿物-岩石学特征，划分了它们的化学-岩石类型：6块属于非平衡型普通球粒陨石(H3和L3群各3块)；92块属于平衡型普通球粒陨石，包括：H群24块(13块H4，10块H5，1块H6)，L群64块(2块L4，44块L5，18块L6)，LL群4块(3块LL4，1块LL5)；另外两块属于石-铁陨石。6块非平衡型普通球粒陨石保存了原始的岩石学和矿物化学特征，包括：清晰的球粒结构、橄榄石和低钙辉石具有明显的成分环带以及极不均一的化学组成等。92块平衡型普通球粒陨石中的橄榄石和低钙辉石显示出均一的化学组成，表明它们达到了一定的热力学平衡。
