The succession of the volcanic sequence in the island is broadly divided into pre- and post-caldera collapse units although a well-constrained chronological identification of the well-defined successive volcanic episodes is still needed. A new paleomagnetic investigation was carried out on 157 samples grouped in 20 sites from the volcanic deposits of Deception Island (South Shetlands archipelago, Antarctic Peninsula region) distributed in: (1) volcanic breccia (3 sites) and lavas (2 sites) prior to the caldera collapse; (2) lavas emplaced after the caldera collapse (10 sites); and (3) dikes cutting pre- and the lower- most post-caldera collapse units (5 sites). The information revealed by paleomagnetism provides new data about the evolution of the multi-episodic volcanic edifice of this Quaternary volcano, suggesting that the present-day position of the volcanic materials is close to their original emplace- ment position. The new data have been combined with previous paleomagnetic results in order to tentatively propose an age when comparing the paleomagnetic data with a global geomagnetic model. Despite the uncertainties in the use of averaged paleomagnetic data per volcanic units, the new data in combination with tephra occurrences noted elsewhere in the region suggest that the pre-caldera units (F1 and F2) erupted before 12,000 year BC, the caldera collapse took place at about 8300 year BC, and post-cal- dera units S1 and S2 are younger than 2000 year BC. 000056790 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/CTM2011-26372$$9info:eu-repo/grantAgreement/ES/MINECO/CTM2011-13902-E$$9info:eu-repo/grantAgreement/ES/MINECO/CTM2014-57119-R 000056790 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000056790 590__ $$a2.283$$b2016 000056790 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b71 / 188 = 0.378$$c2016$$dQ2$$eT2 000056790 592__ $$a1.165$$b2016 000056790 593__ $$aEarth and Planetary Sciences (miscellaneous)$$c2016$$dQ1 000056790 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000056790 700__ $$aGil-Peña,I. 000056790 700__ $$aMaestro, A. 000056790 700__ $$aLópez Martínez, J. 000056790 700__ $$aGalindo-Zaldivar, J. 000056790 700__ $$0(orcid)0000-0002-1929-8850$$aSoto, R. 000056790 700__ $$0(orcid)0000-0001-6110-1081$$aGil Imaz, A.$$uUniversidad de Zaragoza 000056790 700__ $$aRey, J. 000056790 700__ $$0(orcid)0000-0002-1460-1590$$aPueyo, O.$$uUniversidad de Zaragoza 000056790 7102_ $$12000$$2428$$aUniversidad de Zaragoza$$bDpto.
