Loess comes from the German Löss or Löß, and ultimately from Alemannic lösch meaning loose as named by peasants and masons along the Rhine Valley.

SYNONYMS OR RELATED TERMS: pollen analysis CATEGORY: related field; technique DEFINITION: The study of fossil and living spores (of lichens and mosses) and pollen (of flowering plants); the technique through which the fossil pollen grains and spores from archaeological sites are studied.

The outer skin (exine) of these grains is remarkably resistant to decay, and on wet ground or on a buried surface, it will be preserved, locked in the humus content.

The examination of their production, dispersal, and applications is an aid to the reconstruction of past vegetation and climates and developing relative chronologies.

Each kind of flowering plant produces pollen that is unique and pollen grains have tough coverings that can last a long time.

Calthemites which occur on concrete structures, are created by completely different chemistry to speleothems.
