Resumo(s)
Storm- and tsunami-deposits are generated by similar depositional mechanisms making their discrimination hard to establish using
classic sedimentologic methods. A promising approach is to use rock magnetism techniques to search for new physical benchmarks of tsunami deposits and to integrate them into a multi-disciplinary study. To test our
method, we investigate the 1755 Lisbon tsunami deposit from the Boca do
Rio estuary and other Tsunami-induced deposits from Algarve (Portugal)
and Huelva (Spain), as well as storm-like deposits for comparison. Magnetic
methods repose on bulk (magnetic susceptibility, SIRM, Hc) and directional
(AMS, paleomagnetism) magnetic properties.
