Abstract
<jats:title>Abstract</jats:title><jats:p>Volcanic ash layers are important markers for the chronostratigraphy of paleoclimate and paleoenvironmental archives at the southern tip of South America. However, this requires that tephras are well-dated. We report geochemical data from stalagmite MA1 formed in a non-karst cave near Mt. Burney volcano in southernmost Patagonia (~53°S). High-resolution LA-ICP-MS analyses, SEM imagery, EPMA data, and NanoSIMS enable to identify volcanogenic signals during the last 4.5 kyrs from sub-annual trace element variations and tephra particles in distinct laminae. Our new <jats:sup>230</jats:sup>Th/U-chronology of MA1 provides precise dating of tephra from Mt. Burney (MB) and, probably, Aguilera (A) at 4,216 <jats:sup>+93</jats:sup>/<jats:sub>−193</jats:sub> yrs BP (MB<jats:sub>2</jats:sub>), 2,291 ± 33 yrs BP (MB<jats:sub>3</jats:sub>), 853 <jats:sup>+41</jats:sup>/<jats:sub>−60</jats:sub> yrs BP (MB<jats:sub>4</jats:sub>) and 2,978 <jats:sup>+91</jats:sup>/<jats:sub>−104</jats:sub> yrs BP (A<jats:sub>1</jats:sub>). This unique high-resolution record holds potential to date further eruptions from Southern Andean volcanoes for the tephrochronology in this critical region, and potentially also large-volume explosive volcanism off South America.</jats:p>
