AB The elemental content—mainly trace elements—of samples from two boreholes (PLN,CM) with evidence of tsunamiites, located in the Doñana National Park (SW Spain), were studied.The geochemical variations of the REE, LILE, HFSE, and other elements (Al, Ti, S, Na, Br, Sc, Co, Cr)were interpreted according to the mineralogy present in the samples. The results obtained show thegeochemical complexity of the estuarine paleoenvironments, in this case with the existence of threeHolocene-age tsunamigenic deposits (around 4.25, 3.56 and 2.2–2 kyr BP). The statistical analysis ofthe samples’ geochemistry, by means of linear correlation and factor analysis, made it possible todifferentiate two associations. The first is representative of an inherited mineralogy (REE-Y-Rb-Sr-Cs-Th-U-Hf-Al-Ti-Co-Cr-Sc); the second includes elements (Br-Na) linked to mineral formationunder evaporite conditions (halite). The trace element geochemistry of sediments thus becomes anexcellent tool to identify tsunamiites in the studied zone, especially those elements that are clearproxies for marine incursions (Na, Br, Sr) and high energy events (Hf, Ti). The parent area of theprovenance of the materials is mainly of felsic composition.
