We present the first geochemically confirmed finding of the Laacher See Tephra (LST) on the Swedish mainland, now the northernmost extension of the LST. Sediments were sampled at the K€ orsl€attamossen fen, southernmost Sweden, and a high-concentration cryptotephra occurrence (>65000 shards cm ) of the LST was found in a sequence of calcareous gyttja. Tephra identification was confirmed by geochemical analysis using fieldemission electron probe microanalysis and through comparison of the results with published LST data from proximal sites and distal sites north-east of Laacher See. The LST has previously been divided into eruption phases suggested to have spread in several dispersal fans, but it was not possible to confidently determine the phase of the tephra here closer than to the MLST or ULST. The finding of the LST presented here further strengthens the potential of tephrochronological studies in the south Scandinavian region. # 2018 The Authors.
