Alluvial deposits
Products of rock erosion carried in water and deposited as sediments at the bottom of seas and lakes during relatively recent geological periods.

obsidian
Black volcanic glass, suitable for the manufacture of resistant sharp tools.

Palynology
The science studying the flora of earlier period, by examining palynomorphs. Palynomorphs include plant (usually pollen) and animal structures, microscopic in size (ranging from 5 to 500 µm), and are composed of material especially resistant to most forms of corrosion. Pollen is collected from edaphological nuclei, which reveal the succession of geological chronological periods. Coring relies on the extraction of carrot-shaped soil samples (cores) from lake and swamp deposits, the study and identification of pollen grains contained therein, and the compilation of pollen charts, which provide information on the flora of the wider region over large periods of time.

Urfirnis technique
A technique for crafting pottery wares, with glaze creating a silky surface, without burnishing. In Boeotia it appears in the final years of the Middle Neolithic period.
