Post-glacial eruptive history of Chile

Dataset from K Fontijn, SM Lachowycz, H Rawson, DM Pyle, TA Mather, JA Naranjo, H Moreno-Roa, Late Quaternary tephrostratigraphy of southern Chile and Argentina, Quaternary Science Reviews 89, 70 - 84. [Open Access] doi: 10.1016/j.quascirev.2014.02.007 Post-glacial eruptive history of SVZ and AVZ volcanoes, as known from the historical and geological record. Calendar age is given in years before 1950 AD (historical eruptions or varve-dated), ka (Ar-Ar or stratigraphically constrained), or ka cal BP for14C ages. Uncalibrated 14C ages are given where available, and were calibrated in OxCal4.2 (Bronk Ramsey, 2009) using the SHCal13 calibration curve (Hogg et al., 2013). The most important eruptions are highlighted in blue; the large (V > 1 km3) eruptions for which dispersal data are available are highlighted in red. These eruptions are thought to have left significant regional marker horizons which should be readily identifiable in sediment sections. Numbered references can be found in Supplementary Information.

本数据集源自K Fontijn、SM Lachowycz、H Rawson、DM Pyle、TA Mather、JA Naranjo、H Moreno-Roa的研究成果，相关论文题为《智利南部与阿根廷晚第四纪火山碎屑地层学》（Late Quaternary tephrostratigraphy of southern Chile and Argentina），发表于《第四纪科学评论》（Quaternary Science Reviews）第89卷，页码70至84，为开放获取（Open Access）文献，DOI: 10.1016/j.quascirev.2014.02.007。

该数据集基于历史记录与地质资料，梳理了南美火山弧带（Southern Volcanic Zone, SVZ）与安第斯火山弧带（Andean Volcanic Zone, AVZ）火山的冰后喷发历史。其年代学数据采用三类标注方式：公元1950年之前的年份（适用于历史喷发事件或纹泥定年样品）、千年尺度绝对年龄（ka，适用于Ar-Ar定年或地层约束样品），以及14C定年所用的校正后距今千年年龄（ka cal BP）。若可获取未校准的14C年龄数据，将一并提供；所有年龄均通过OxCal4.2软件（Bronk Ramsey, 2009）结合SHCal13校准曲线（Hogg et al., 2013）完成校准。

研究中识别的关键喷发事件以蓝色高亮标注；已有扩散数据的大型（体积V＞1 km³）喷发事件以红色高亮标注。此类喷发被认为留下了显著的区域性标志层，可在沉积剖面中便捷识别。编号参考文献详见补充材料（Supplementary Information）。
