CONFERENCE # 2 - Monday 28 January
Diatoms as markers in biostratigraphy
The ancient diatom floras in diatomites settled in lacustrine basins along the world contain distinctive
species and genera that have been calibrated with radiometric ages. Neogene deposits can be arranged
geochronologically to become useful biostratigraphic markers. Diatom biochronology is the same
elsewhere in North America and in Eurasian continent. The stratigraphy and geologic ranges of
distinctive diatom taxa will be presented, useful for indicating Neogene climates, lacustrine levels and
paleoenvironments.
