Abstract(Summary)
All the major groups of palynomorphs - acritarchs, chitinozoans, dinocysts, and miospores - show a remarkable degree of morphologic diversity. But how can we use that rich diversity to our scientific advantage? Firstly their microscopic size means that they are much more abundant in rocks than are macrofossils. Secondly, their diversity makes them excellent stratigraphic markers in rocks of Proterozoic to Quaternary age. Thirdly, their occurrence in terrestrial to oceanic rocks allows for extensive interpretation of paleoenvironments. And fourthly, through kerogen analysis and measurement of thermal alteration studies, they provide significant insights into the oil and/or gas-prone nature of source rocks and their degree of maturity. Thus, palynology plays a critical role in oil exploration, providing biostratigraphic, paleoenvironmental, and maturation data, possibly unrivalled by any other group of fossils. Palynology thus involves the study of small fossils with a big impact.
Summary(Plain Language Summary, not published)
Palynology is the study of microscopic organisms or parts of organisms, collectively known as palynomorphs, whose walls are composed of acid-resistant organic material. All major groups of palynomorphs ? acritarchs, chitinozoans, dinoflagellate cysts and miospores (pollen and small spores mostly of vascular plants) show a remarkable degree of morphologic diversity, Their microscopic size means that they are much more abundant in rocks than are macrofossils. Their diversity makes them excellent stratigraphic markers and paleoenvironmental indicators in rocks of Proterozoic to Quaternary age. And through kerogen analysis and measurement of thermal alteration, they provide significant insights into the oil and/or gasprone nature of source rocks and their degree of maturity.
