陨石岩石类型的确定，主要根据陨石中球粒及基质的特征，参考其它标志，如橄榄石成分、辉石的结构、长石的特征等进行分类，效果较好。

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。

Basic characteristics and prevailing genetic models of Chondrites have been introduced and commented. Unusu-al features of Chondrites from the Lower-Middle Ordovi-cian transition have been reported in the west-central Utah, USA. They include that tiny Chondrites -were cut by other trace fossils associated with them and formed in softground, and that Chondrites were the earliest or shallowest tiering in the complex ichnofabrics.

介绍和评述Chondrites的基本特征和流行的成因解释，记述最近发现于美国犹他州中西部北美下-中奥陶统之交层型剖面上的Chondrites遗迹组构的不寻常特征和属性：细小的Chondrites被所有与之共生的遗迹化石交切，形成于水与沉积物界面附近缺氧的早期软底质中，Chondrites是形成最早和最浅的遗迹阶层。

The measurement of TL sensitivity has produced new means of classification for 3 type of ordinary chondrites,CO,CV chondrites and eucrites.

诱导TL曲线的峰温和峰宽也与陨石的热历史有关。

The study and comprehensive analysis of static high-pressure quenching experiments and laboratory dynamic high-pressure experiments on chondrites,as well as the study of shock-induced phase transition of minerals in the Suizhou meteorite revealed that the P-T conditions for phase transition of minerals during natural impact events,such as collision of cosmic bodies or impact of meteorites on the Earth′s surface,are not consistent with those obtained by shock experiments on chondrites or rocks in laboratory,...

通过对球粒陨石的静态高压淬火实验和人工动态高压实验的研究和综合分析，以及对在太空中经受过撞击的随州陨石中矿物发生高压相变的研究，查明了自然界的冲击事件，如星体的相互碰撞和陨石对地球表面的撞击中，矿物发生相变的P-T条件与人工冲击波实验的结果并不一致，而与静态高压淬火实验的结果相似，即前者类似静态高压淬火实验，保压时间较长，能产生高压矿物，后者保压时间极短，无高压矿物形成。

The others include 1 martian meteorite, 1 HED meteorite and 6 L3 ordinary chondrites. These 20 equilibrated ordinary chondrites are classified into chemical groups of H, L and LL, respectively, based on mean Fa content of oli-vine, mean Fs of low - Ca pyroxene and abundance of Fe-Ni metal.

根据橄榄石的平均Fa值、低Ca辉石的平均Fs值和Fe-Ni金属含量将这20块陨石分别划分为H、L和LL等化学群；根据球粒结构、基质重结晶程度和矿物成分对这些陨石进行岩石类型的划分。
