Smithsonian Abyssal Volcanic Glass Data File

The Smithsonian Abyssal Volcanic Glass Data File contains over 10,000 natural glasses from the sea floor analyzed by electron microprobe in the Department of Mineral Sciences. Analytical procedures were developed in the early 1970s by Gene Jarosewich and William Melson. Tim O'Hearn began analyzing specimens in 1976 and refined these procedures. The sea floor glasses are from mid-ocean ridge spreading centers, fracture zones, seamounts, back-arc basins, and trenches from around the globe. The majority of the specimens for this collection were donated to the Petrology Collection and analyzed by the electron microprobe with the understanding that the analyses were given to the donor for their privileged use for a year, then merged into our database.The dataset published here includes three files:• smithsonian_abyssal_volcanic_glass_data_file.xlsx• smithsonian_abyssal_volcanic_glass_data_file_chemistry.csv• smithsonian_abyssal_volcanic_glass_data_file_references.csvThe XLSX file is the original file provided by the authors updated to use the XLSX file format. The CSV files are plain-text versions of each tab from the original workbook modified only to remove empty rows and strip whitespace from individual cells.For additional information about this dataset, see the following publication: Melson, W. G., O'Hearn, T., and Jarosewich, E., A data brief on the Smithsonian Abyssal Volcanic Glass Data File, Geochem. Geophys. Geosyst., 3(4), doi:10.1029/2001GC000249, 2002.

史密森尼博物院深海火山玻璃数据文件汇集了超过10,000件海底天然玻璃样本，这些样本由矿物科学部利用电子探针进行分析。该分析程序由Gene Jarosewich和William Melson于20世纪70年代初开发。Tim O'Hearn于1976年开始对这些样本进行分析，并对其程序进行了细化。这些海底玻璃样本来源于全球中洋脊扩张中心、断裂带、海山、后弧盆地和海沟。本收集的大部分样本均由岩石学收藏捐赠，并使用电子探针进行分析，捐赠者有权在一年内优先使用分析结果，之后并入我们的数据库。本处发布的数据库包含三个文件：
• smithsonian_abyssal_volcanic_glass_data_file.xlsx
• smithsonian_abyssal_volcanic_glass_data_file_chemistry.csv
• smithsonian_abyssal_volcanic_glass_data_file_references.csv
其中，XLSX文件为作者提供的原始文件，已更新为XLSX格式。CSV文件是原始工作簿中每个标签页的纯文本版本，仅进行了移除空行和去除单个单元格空白字符的修改。关于本数据集的更多信息，请参阅以下出版物：Melson, W. G., O'Hearn, T., Jarosewich, E.，关于史密森尼博物院深海火山玻璃数据文件的简报，Geochem. Geophys. Geosyst.，3(4)，doi:10.1029/2001GC000249，2002。
