Post-glacial eruptive history of Volcán Mocho-Choshuenco, Chile; large dataset of glass, Fe-Ti oxide analyses, Radiocarbon dates and isopach data

Dataset from H. Rawson, J. Naranjo, V. Smith, K. Fontijn, D. Pyle, T. A. Mather, H. Moreno. (2015) The frequency and magnitude of post-glacial explosive eruptions at Volcán Mocho-Choshuenco, southern Chile, <em>Journal of Volcanology and Geothermal Research </em> doi:10.1016/j.jvolgeores.2015.04.003 We have reconstructed a high resolution, post-glacial eruption history of Volcán Mocho-Choshuenco (39°55’S 72°2’W). In the dataset attached: SD1: GPS localities of key outcrops SD2: ~2150 major element glass analyses from 22 tephra units (eruptions); analysed on EMP SD3: ~2700 Fe-Ti oxide analyses from 19 tephra units (eruptions); analysed on EMP SD4: Secondary standard data; analysed on EMP SD5: 48 Radiocarbon samples; uncalibrated 14C ages, calibrated ages (using OxCal4.2 (Bronk Ramsey, 2009) and SHCal13 calibration curve (Hogg et al., 2013)). SD6: Maximum pumice, maximum lithic and thickness measurements for three Plinian and two sub-Plinian eruptions.

本数据集源自H. Rawson、J. Naranjo、V. Smith、K. Fontijn、D. Pyle、T. A. Mather、H. Moreno于2015年发表于《Journal of Volcanology and Geothermal Research》（火山学与地热研究杂志）的研究成果，DOI：10.1016/j.jvolgeores.2015.04.003。本研究重建了智利南部Mocho-Choshuenco火山（南纬39°55′，西经72°2′）的高分辨率冰期后喷发历史。附件数据集包含如下内容：
SD1：关键露头的全球定位系统（GPS）采样点位；
SD2：来自22个火山碎屑单元（对应单次喷发事件）的约2150项主量元素玻璃组分分析数据，测试采用电子探针显微分析仪（Electron Microprobe, EMP）；
SD3：来自19个火山碎屑单元（对应单次喷发事件）的约2700项铁-钛氧化物分析数据，测试采用电子探针显微分析仪；
SD4：二级标准物质分析数据，测试采用电子探针显微分析仪；
SD5：48份放射性碳（Radiocarbon）样品数据，包含未校正的14C年龄，以及经OxCal4.2（Bronk Ramsey, 2009）与SHCal13校正曲线（Hogg et al., 2013）校准后的年龄值；
SD6：3次普林尼式（Plinian）喷发与2次次普林尼式（sub-Plinian）喷发的最大浮岩含量、最大岩屑含量及喷发厚度测量数据。
