Abstract

This study examines tephra layers from lacustrine sediment cores collected in Patagonian Andean Range, correlating them with volcanic sources from the southern segment of the Southern Volcanic Zone (SVZ). Ten distinct tephra layers, spanning approximately the last 2000 yr, were identified across four cores from Lakes Rivadavia, La Zeta, Brychan, and Theobald, from ∼42°S to 44°S. Mostly geochemical and mineralogical analyses of tephra components (pumice, glass shards, scoria) reveal that the Chaitén, Michinmahuida, and Huequi volcanoes are the main sources of tephra in the region. Identified eruptions include four from Chaitén (ca. 2008 CE, ca. twelfth, ca. eighth, and fourth to fifth centuries), two from Huequi (beginning of the nineteenth and, possibly, fourteenth centuries), and four from Michinmahuida (ca. seventeenth to eighteenth, thirteenth, eighth, and ca. second centuries). Four of these tephra layers also have potential as isochronous marker beds in the region, allowing a preliminary reconstruction of their regional dispersal patterns. Some tephras may represent previously undocumented or scarcely documented eruptions. These findings suggest that the eruptive frequency in the southern SVZ has been underestimated, emphasizing the need for further research to expand the eruptive history and more accurately assess the volcanic hazards associated with this region.
