A succession of fine dark and light laminations, covering a time span of ca 6,000 years (Allerød to Atlantic), was observed in the sediment of Soppensee, Central Switzerland. These laminations, consisting of dark, organic and diatom-rich winter/spring layers and light calcite summer layers, are shown to be varves by means of several independent pollen and diatom analyses, as well as thin-section studies of the sediment micro-structure.
