论文摘要
我们在这里介绍了对刚倒下的Mukundpura CM软管进行的几项实验室分析。红外传播光谱，热重法分析和反射率光谱的结果表明，Mukundpura主要由Phyllosilicates组成。可溶性有机物（SOM）的稀土痕量元素组成和超高分辨率质谱法给出了与CM软管一致的结果。最后，拉曼光谱没有显示陨石热改变的迹象。所有结果都同意，穆肯布拉（Mukundpura）在其母体上被水强烈改变。对陨石获得的结果与已知岩石学类型的其他软骨的结果的比较得出的结论是，Mukundpura类似于CM1软骨，这与其原始分类为CM2不同。
We present here several laboratory analyses performed on the freshly fallen Mukundpura CM chondrite. Results of infrared transmission spectroscopy, thermogravimetry analysis and reflectance spectroscopy show that Mukundpura is mainly composed of phyllosilicates. The rare earth trace elements composition and ultrahigh resolution mass spectrometry of the soluble organic matter (SOM) give results consistent with CM chondrites. Finally, Raman spectroscopy shows no signs of thermal alteration of the meteorite. All the results agree that Mukundpura has been strongly altered by water on its parent body. Comparison of the results obtained on the meteorite with those of other chondrites of known petrologic types lead to the conclusion that Mukundpura is similar to CM1 chondrites, which differs from its original classification as a CM2.
