The study of the palynofacies of a sedimentary depositional environment can be used to learn about the depositional palaeoenvironments of sedimentary rocks in exploration geology, often in conjunction with palynological analysis and vitrinite reflectance.Palynofacies can be used in two ways: who described pollen and the stamen, and concluded that pollen is required for sexual reproduction in flowering plants.Palynology does not include diatoms, foraminiferans or other organisms with siliceous or calcareous exoskeletons.Palynology as an interdisciplinary science stands at the intersection of earth science (geology or geological science) and biological science (biology), particularly plant science (botany).They are extracted from sedimentary rocks and sediment cores both physically, by ultrasonic treatment and wet sieving, and chemically, by chemical digestion to remove the non-organic fraction.Palynomorphs may be composed of organic material such as chitin, pseudochitin and sporopollenin.The isolation ended with the German publication of Gunnar Erdtman's 1921 thesis. Hyde and Williams chose palynology on the basis of the Greek words paluno meaning 'to sprinkle' and pale meaning 'dust' (and thus similar to the Latin word pollen).The methodology of pollen analysis became widespread throughout Europe and North America and revolutionized Quaternary vegetation and climate change research. Sarauw studied fossil pollen of middle Pleistocene age (Cromerian) from the harbour of Copenhagen. Pollen analysis in North America stemmed from Phyllis Draper, an MS student under Sears at the University of Oklahoma.

A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age.

Pollen analysis is also sometimes useful in exploration for resources of fossil fuels.

: the identification and determination of frequency of pollen grains in peat bogs and other preservative situations as a means of dating fossil and other remains : the study of past vegetations and climates as indicated by the pollen content of the various layers of the earth's surface You must — there are over 200,000 words in our free online dictionary, but you are looking for one that’s only in the Merriam-Webster Unabridged Dictionary.

As a result, these microfossils give important clues to the prevailing climatic conditions of the time.

Their paleontological utility derives from an abundance numbering in millions of cells per gram in organic marine deposits, even when such deposits are generally not fossiliferous.
