陨石

The outer, non-metallic layers of the planet form what are known as achondrite stony meteorites, and there is a separate class of stony-irons that come from the boundary between inner core and outer layer.

位于行星外部的非金属层形成无球粒陨石石质陨石，在内核和外层之间还存在有一层独立的石质铁层。

The site also contains images and photomicrographs of meteorites and impact craters. There is a comprehensive bibliography and glossary of terms, and list of Arizonan meteorites. The site is available in English and Spanish.

The large number of meteorites from Antarctica and the desert areas of Australia,Africa and North America changed the previous chondrite classification in recent years.

近年来在南极及澳大利亚、非洲和北美的沙漠地区发现和回收了大量的陨石，改变了以前的球粒陨石分类。

The Ningqiang carbonaceous chondrite is the first falling carbonaceous chondrite in China, The ge...

宁强碳质球粒陨石是中国第一块降落的碳质球粒陨石。

If you look over the element ratios we measured, you might conclude that our comet particles look more like chondritic porous IDPs than CI chondrite meteorites.

如果你查看我们测定的元素比率，你将得出结论——我们的彗星颗粒看上去更接近多孔球粒陨石 IDPs 而不是 CI 球粒陨石。

Two types of olivine in the Dongujimqin mesosiderite were identified: the matrix olivine and the brecciform olivine.

东乌珠穆沁旗中铁陨石中有二种橄榄石。一种是陨石中基质橄榄石，另一种是镶嵌在陨石表面的角砾状橄榄石。

Irons, stony-irons, chondrites, and achondrites are by no means equally abundant among observed meteorites.

铁矿、陨铁石、球粒状陨石及无球粒陨石在可观测到的陨石中绝不多见。

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。

Irons, stony-irons, chondrites, and achondrites are by no meansequally abundant among observedmeteorites.

铁矿、陨铁石、球粒状陨石及无球粒陨石在可观测到的陨石中绝不多见。

Accordingly, their refractory element contents are higher than those of the Australiasian tektites. Only one out of the 9 spherules of the ODP 1144 microtektites exhibits low Al2O3 abundance, 13.0%. Also, the contents and some ratios of the refractory elements of this spherule differ much from the other ODP 1144 microtektites, but similar to those of the tektites from Zhanjiang and Wuchun.

从成分上看，这些微玻璃陨石存在两种不同的类型，其中的绝大部分Al2O3含量在19.0%以上，属于高Al类型，相应的难熔微量元素含量也比较高；个别微玻璃陨石Al2O3含量(13.0%)和难熔微量元素含量较低，微量元素含量和特征比值都与邻近的广东省湛江和吴川的玻璃陨石相近。
