dc.description.abstractRare Earths (REE) were investigated in siliceous stromatolites forming in the Specchio di Venere Lake in Pantelleria Island. Chondrite-normalised patterns show significant La enrichments and Eu depletions suggesting that fluids involved in stromatolite growth experienced strong rock-water interactions under hydrothermal conditions. At the same time, enrichments of heavy REE (HREE), with respect to intermediate REE (MREE) suggest that hydrothermal fluids interacted with microbial mats during deposition of stromatolites. The above-mentioned features suggest that rock-water interactions and bacterial activity were simultaneously recorded in REE patterns of stromatolites and can be discriminated in terms of amplitudes of La anomaly and HREE/MREE ratioen
