close up with descriptions

Description: Varved sediment from Lake Nar (Turkey). The thin section micrograph from NAR 01/02 is illustrating carbonate (appears grey/white), diatom bloom of Stephanodiscus parvus (pale yellow) and organic layer (brown) over 2-3 varve layers. Note that diatom bloom layers do not occur every year.
Picture Type: microscopic

Description: Thin sections from Nar Lake, Turkey, highlight the different seasonality of diatom blooms and their differing relationship with carbonate precipitation. One blooming taxon (Nitzschia paleacea) always immediately precedes carbonate precipitation; the other (Synedra acus) does not.
