Palynology Palynology The Blytt-Sernander classification, or sequence, is a series of north European climatic periods or phases based on the study of Danish peat bogs by Axel Blytt (1876) and Rutger Sernander (1908). The classification was incorporated into a sequence of pollen zones later defined by Lennart von Post. ...more on Wikipedia about "Blytt-Sernander"
Ganapathi Thanikaimoni ( January 1, 1938 – September 6, 1986), often referred to as Thani was widely known for his manifold contributions to the science of palynology. He was married to Krishnaveni (aka Kitty) in 1970 and the couple had a son Ravindran (aka Ravi) and a daughter called Kirthana. ...more on Wikipedia about "Ganapathi Thanikaimoni"
The Older Dryas was a somewhat variable cold, dry Blytt-Sernander period of North Europe, roughly equivalent to Pollen zone 1c. It is named after an indicator genus, Dryas, which flourished during the penultimate stadial of the Pleistocene. The Older Dryas period was preceded by the Bølling and followed by the Allerød periods. ...more on Wikipedia about "Older Dryas"
The Oldest Dryas is a climatic period, which occurred during the coldest stadial after the Weichselian glaciation in north Europe. In the Alps, the oldest Dryas corresponds to the Gschnitz stadial of the Wurm glaciation. The three “Dryas” periods (younger, older, oldest) are named for a marker species, Dryas octopetala, detected in core samples of glacial ice and peat bogs. The oldest Dryas corresponds to Pollen zone 1a. ...more on Wikipedia about "Oldest Dryas"
Palynofacies studies examine the preservation of particulate organic matter and palynomorphs to provide information on the depositional environment of sediments and depositional palaeoenvironments of sedimentary rocks. The term Palynofacies was introduced by the French geologist Combaz in 1964. Palynofacies studies are often linked to investigations of the palynology and organic geochemistry of sedimentary rocks. ...more on Wikipedia about "Palynofacies"
Palynology is the science that studies contemporary and fossil palynomorphs, including pollen, spores, dinoflagellate cysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimentary rocks and sediments. ...more on Wikipedia about "Palynology"
Pollen is a fine to coarse powder consisting of microgametophytes (pollen grains), which carry the male gametes of seed plants. Each pollen grain contains one or two generative cells (the male gametes) and a vegetative cell. The group of three cells is surrounded by a cellulose cell wall and a thick, tough outer wall made of sporopollenin. ...more on Wikipedia about "Pollen"
Pollen zones are a system of subdividing late Pleistocene and early Holocene paleoclimate using the data from pollen cores. The sequence provides a global chronological structure to a wide variety of scientists, such as geologists, climatologisists, geographists and archaeologists, who study the physical and cultural environment of the last 15,000 years. ...more on Wikipedia about "Pollen zone"
