中国南极科考队汇集陨石数据集

中国南极科考队汇集陨石数据集是中国南极科考队在南极格罗夫山地区开展的7次陨石考察和汇集基础上汇编而成。中国南极科考共回收了12665块陨石样品。目前，3175块陨石获得了国际陨石命名委员会批准，并在陨石公报上刊登，所有陨石标本均保藏在中国极地中心陨石保藏库中。该数据集汇集的陨石信息包括：陨石名称、简称、陨石类型、质量、发现者、发现日期、纬度、经度、块数、冲击程度、风化程度、Fa值、Fs值、Wo值、命名的研究单位等信息。数据集由3部分组成：（1）Excel表格数据，包括3175块陨石的野外基本信息以及陨石的类型、风化程度、冲击变质等级、主矿物化学成分等信息；（2）.kml文件，在Google earth中精确地反映陨石的地理位置、质量和类型等信息；（3）.shp文件，包括了3147块陨石的野外基本信息以及陨石的类型、风化程度、冲击变质等级、主矿物化学成分等信息。压缩后数据量为1.24MB。

The Collected Meteorite Dataset of the Chinese Antarctic Expedition was compiled based on seven meteorite surveys and collection operations conducted by the Chinese Antarctic Expedition in the Grove Mountains region of Antarctica. A total of 12,665 meteorite samples were recovered during these expeditions. Currently, 3,175 of these meteorites have been approved by the International Committee on Meteorite Naming and published in the Meteoritical Bulletin. All meteorite specimens are preserved in the Meteorite Repository of the Chinese Polar Research Center.

The meteorite information contained in this dataset includes: meteorite name, abbreviation, meteorite classification, mass, discoverer, discovery date, latitude, longitude, number of specimens, shock grade, weathering grade, Fa value, Fs value, Wo value, and the research institution responsible for the meteorite naming, as well as other relevant details.

This dataset consists of three parts:
1. Excel spreadsheet data, which includes basic field information of 3,175 meteorites, as well as their classification, weathering grade, shock metamorphism grade, major mineral chemical composition and other related information;
2. .kml files that accurately display the geographic location, mass, classification and other information of the meteorites in Google Earth;
3. .shp files, which contain basic field information of 3,147 meteorites, as well as their classification, weathering grade, shock metamorphism grade, major mineral chemical composition and other related information.

The total size of the compressed dataset is 1.24 MB.
