21世纪的第一个十年,陨石学与天体化学研究在中国迎来了一个前所未有的发展时期。在南极格罗夫山地区共开展了5次科学考察,收集到超过1万块陨石,提供了珍贵的研究样品;嫦娥工程的立项和一期工程的成功实施,是陨石学与天体化学发展的重大机遇,也是挑战;高精度原位微区分析平台建设的完成,则为地外物质样品的分析提供了关键的技术保证。更为重要的是,通过大量南极陨石的分类工作,培养和锻炼了陨石学研究的青年人才。在此基础上,通过对各化学群陨石的研究,取得了许多重要的成果,包括陨石中前太阳颗粒的发现和研究、陨石中的灭绝核素、太阳星云在不同条件下的凝聚过程、月球陨石和火星陨石的岩石学成因与同位素定年、陨石的冲击变质与高压矿物、以及中国第一个陨石坑的证实等。 |

In the first 10 years of 21st century, meteoritics and cosmochemistry made significant progress in China. During 5 times of Chinese Antarctic Research Expeditions, more than 10 thousands of meteorites have been collected from Grove Mountain areas, supplying with precious extraterrestrial samples. The study of meteoritics and cosmochemistry has also been promoted by Chang'e mission and the great success in the first episode of Chinese lunar exploration, and is challenged by the demands of space exploration. Various high precision and high laterial resolution measurements of extraterrestrial samples are now available with a number of newly established facilities and equipments. Furthermore, many young researchers have been involved in cosmochemistry and trained via classifying the large number of Antarctic meteorites. By studying of various groups of meteorites, numerous discoveries have been made, inclusing presolar grains in primitive chondrites, short lived radionuclides, condensation processes of the solar nebula under different redox conditions, petrogenesis and isotopic dating of lunar meteorites and martian meteorites, shock metamorphism and high pressure polymorphs in shocked meteorites, and confirmation of the first meteorite impact crater in China. |
