Problems of Holocene climatostratigraphy on the territory of Poland

The pre sented cli ma to stra tigra phy of the Holo cene on the ter ri tory of Po land is based on a range of bi otic, sedi men tologi cal, geo mor pho logi cal and iso topic rec ords, but also takes into ac count fluc tua tions of tem pera ture and hy dro logical re gime. The author up holds the tra di tional di vi sion of the Holo cene into three ther mic phases and dis cusses inde tail dis tinct fluc tua tions in the hy dro logi cal re gime re flected in the al tera tion of wet ter and drier phases. Al though their pro files tend to be blurred, the lower bounda ries of the wet ter phases, which set off the trans for ma tion of geoe cosys tems (a pro cess re flected in the first clus ters of ex treme events), may be used to iden tify re gional stra tigraphic subdi vi sions. The su per im posed phases of hu man ac tiv ity have much smaller spa tial ex tent.
