Here we propose a new dating approach based on the comparison of a speleothem\u2019s paleomagnetic directions to reference curves from global paleomagnetic reconstructions. This approach is demonstrated on a stalagmite collected from the Soprador do Carvalho cave in the Central Region of Portugal. A radioisotopic age model, built using four U-series ages and three <jats:sup>14<\/jats:sup>C, suggests relatively steady carbonate precipitation from\u2009~\u20095760 BCE until\u2009~\u20091920 CE. Forty-five 6\u00a0mm-thick subsamples were analyzed using alternating field and thermal demagnetization protocols, providing well-defined, primary magnetic directions. An age model of the stalagmite was obtained by fitting its paleomagnetic record with the reference paleosecular variation curves obtained by previous paleo-reconstruction models, applying statistical bootstrapping analysis to define their best fit. The resulting age models fit closely with the radioisotopic age model but provide a significantly higher time resolution. We reach the same conclusion when applying this approach to another stalagmite from the Algarve region of Portugal. Our approach thus appears a promising alternative to date young speleothems with high detrital contents.<\/jats:p>","DOI":"10.1038\/s41598-022-21761-9","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T09:35:48Z","timestamp":1666776948000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Paleomagnetic techniques can date speleothems with high concentrations of detrital material"],"prefix":"10.1038","volume":"12","author":[{"given":"Elisa M.","family":"S\u00e1nchez-Moreno","sequence":"first","affiliation":[]},{"given":"Eric","family":"Font","sequence":"additional","affiliation":[]},{"given":"F.
