陨石学

Petrography and mineral chemistry of 100 meteorites collected from the Grove Mountains,Antarctica,were studied and their chemical-petrographic types were assigned.

本文主要报道了南极格罗夫山新回收的100块陨石的岩石学和矿物化学特征。

There is an introduction to Mars meteorites, and detailed descriptions of individual Mars meteorites. Each document about the individual meteorites contains all existing information such as petrography, whole rock and mineral chemistry, radiogenic, cosmogenic and stable isotope data and weathering.

该站点详细的介绍了火星陨石及其各自的具体特点，这些以PDF格式保存的档案文件包含了岩石记述学、岩石和矿物化学、射电数据、宇宙测年数据、稳定同位素数据等。

It may be the third largest iron meteorite in China. Fe content is 94.02%, Ni content 5.29%, and Co 0.45% in the iron meteorite. The main mineral is kamacite, and crystal and aggregate of schreibersite were also found in the iron meteorite.

通过初步的化学分析和矿物学分析，发现其铁含量为94.02%，镍含量为5.29%，钴含量为0.45%，主要矿物为铁纹石，局部含有陨磷铁镍石的晶体或集合体，表明它是一块典型的铁陨石。

Furthermore,according to their petrologic features and mineral chemistry,21 groups of meteorites are pre...

经过岩石矿物学特征和矿物成分的对比分析，初步判定成对陨石21组。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
