Pollen analysis dating
The term was introduced by the French geologist André Combaz in 1964.Palynofacies studies are often linked to investigations of the organic geochemistry of sedimentary rocks.
Palynomorphs form a geological record of importance in determining the type of prehistoric life that existed at the time the sedimentary formation was laid down.
Pollen analysis advanced rapidly in this period due to advances in optics and computers.
Much of the science was revised by Johannes Iversen and Knut Fægri in their textbook on the subject.
Early investigators include Christian Gottfried Ehrenberg (radiolarians, diatoms and dinoflagellate cysts), Gideon Mantell (desmids) and Henry Hopley White (dinoflagellate cysts). Weber 1918) appear to be among the first to undertake 'percentage frequency' calculations.
Quantitative analysis of pollen began with Lennart von Post's published work. The term palynology was introduced by Hyde and Williams in 1944, following correspondence with the Swedish geologist Ernst Antevs, in the pages of the Pollen Analysis Circular (one of the first journals devoted to pollen analysis, produced by Paul Sears in North America).
