Spores and pollen are allochthonous pelitic particles of biogenic origin, one of the most important floristic groups used for the dismemberment, and correlation of sedimentary sections. The main tool for sediment stratification by palynological data is palynozone. This is a specialized biostratigraphic subdivision - sediments containing a unique set of different categories of taxa (according to the peculiarities of vertical distribution key, characteristic, transit ones; on the content dominant, subdominant, accessory), that combined to zonal complex. The modernized method of definition of palynozone and the newest way of presenting biostratigraphic material in the form of a standardized and unified system of characteristics are offered.
