Multi-proxy analysis (sedimentological, palaeobotanical, geochemical data and results of radiocarbon dating) of the biogenic sediments from a small mire ecosystem in the Sandomierz Basin (SE Poland) is presented. The ecosystem contains a full hydroseral sequence from minerotrophic to ombrotrophic wetland. It is one of the few sites in this region which is so thoroughly investigated in terms of the palaeoenvironmental record. Changes in the water supply of the mire area, and conse-quently the changes in the plant and sediment succession, were well correlated with the regional tendencies in precipitation and temperature during the Late Glacial/Holocene transition and in the Holocene. Human impact is very well recorded in pollen diagram from the Subboreal period.

Vegetation changes in the Lower San Valley near Jarosław are reconstructed from the Younger Dryas to the present time on the basis of palynological analysis of the peat core. The pollen profile came from a an old riverbed and was supplemented by radiocarbon datings. The Younger Dryas and early Preboreal vegetation was characterised by a high proportion of forest communities with pine (Pinus sylvestris and P. cembra) and birch (Betula), while patches of open area were dominated by the steppe with Artemisia. Climatic amelioration during the Preboreal chronozone led to the rapid spread of elm (Ulmus), which was probably a dominant taxon on the lowest terraces of the valley. Terrestrialization of the water body existing in the palaeomeaner and the subsequent beginning of peat accumulation caused a deterioration in pollen preservation. Hence, the interpretation of the profile section spanning the period between the Boreal and Subatlantic chronozones was seriously disturbed due to selective corrosion and the overrepresentation of Pinus sylvestris type and Filicales monolete sporomorphs. Between ca. 336 and 1152 AD fluctuations in woodland cover were recorded. Important components in those forests, despite the domination of Pinus sylvestris, were Quercus, Carpinus betulus, Fagus sylvatica and Abies alba. The first pollen grains of cereals (Cerealia type) were found before ca. 1605-1414 BC and may be attributed to the agricultural activity of the Neolithic and/or early Bronze tribes. Periods of strong deforestation caused by humans were probably related to the time when the Tarnobrzeska Group of the Lusatian Culture and the Przeworska Culture were active. The first groups of Slavs did not significantly influence the environment, but the subsequent development of those groups led to more visible deforestation, which was triggered after the establishment of Jarosław in the 11th century AD.

The sub-Quaternary topography of the western Sandomierz Basin has been compared to variable thicknesses of Quaternary sediments and geomorphology of the area. The lithology and age of the top of Miocene strata have been determined. The Witów Series has been interpreted as a sequence of a braided river that used to flow into the retreating marine basin, forming a fan delta whose age, according to macrofloristic determinations, has been assigned to the Late Miocene. Lower Quaternary gravels cap the remnants of a planated surface situated at 240-250 m a.s.l. The Błonie gravel horizon occurring at a similar altitude was deposited by a river active in Narevian and/or Nidanian glacial stages, and its top underwent reworking during the Sanian-2 stage. Deposits infilling the fossil sub-Carpathian Furrow have been mapped and dated to the Cromerian s.l. interglacial stage. The final alluviation of this segment of the furrow took place during the Sanian-2 stage. Reconstruction of the drainage pattern during the Eopleistocene, South-Polish glaciations, and Masovian inter- glacial stage has been proposed as well.

Charakteryzując torfowiska Kotliny Sandomierskiej uwzględniono ich rozmieszczenie w mezoregionach fizycznogeograficznych, rodzaj i charakter. Wyróżniono 10 obszarów obniżonych w postaci dolin i równin oraz 5 obszarów wyższych o 30–70 m w postaci płaskowyży i podgórzy. Analizowano liczbę, powierzchnię, wielkość złóż torfu, średnią miąższość i popielność złóż oraz ich stratygrafię (złoża szuwarowe, turzycowiskowe, mechowiskowe, olesowe, mszarne przejściowe, brzezinowe przejściowe, mszarne wysokie, złoża pogrzebane i gytiowiska). Omówiono publikowane prace: florystyczne, fitosocjologiczne, palinologiczne, torfoznawcze i paleogeograficzne.

The peatlands of the Sandomierz Basin were characterized according to their location, type and character in physico-geographical mesoregions. Ten lower regions, valleys and planes, and 5 higher regions of 30–70 m above, plateaux and submontane districts, were specified. The number, the surface area and the size of peatlands were analized as well as their average thickness, ash content and stratification (rush, sedge, parvocaricetum, transition bog, bogmoss, alder, transition birch, raised bogmoss, buried and gyttia deposits). Published papers on flora, vegetetion, palynology, peatforming processes and palaeogeography were presented.

Basing on key sections of glacial, lake, fluvial and loessy sediments (the latter with palaeosols), 15 stratigraphical units of the Pleistocene were described and correlated for the area of southeastern Poland and northwestern Ukraine. Eight of these units represent glaciations (Narevian, Nidanian, Sanian 1, Sanian 2, Liviecian, Odranian, Wartanian and Vistulian), and seven are interglacials (Podlasian, Małopolanian, Ferdynandovian, Mazovian, Zbójnian, Lublinian and Eermian). Extents of Scandinavian ice-sheets in this area are presented during the described glaciations, accompanied by tentative correlation to the main stratigraphical units of the pre-Pleistocene and Pleistocene in western and mid-eastern Europe.

Na podstawie analizy 42 reperowych profilów osadów lodowcowych, jeziornych, rzecznych, jaskiniowych i lessowych, z zachowanymi w nich glebami kopalnymi, dokonano charakterystyki i korelacji 15 głównych jednostek podziału stratygraficznego plejstocenu SE Polski i NW Ukrainy. Osiem jednostek reprezentuje odrębne zlodowacenia (nawri, nidy, sanu 1, sanu 2=wilgi, liwca, odry, warty i wisły), siedem - odrębne interglacjały (podlaski=augustowski, małopolski, ferdynandowski, mazowiecki, zbójnowski, lubawski=lubelski i eemski). Poza ostatnim zlodowaceniem lądolody skandynawskie wkroczyły na opisywany obszar pozostawiając osady i formy rzeźby wyznaczające maksymalne zasięgi. Prezentowane opracowanie ściśle nawiązuje zarówno do wcześniejszej korelacji osadów lodowcowych i lessów oraz osadów jeziornych i gleb kopalnych na obszarze wyżyn południowopolskich jak też do prac dotyczących korelacji stratygraficznej lessów polskich i ukraińskich. Dzieki tym pracom i uzyskanym materiałom przedstawiono nową próbę korelacji wiekowej osadów czwartorzędowych zachowanych w profilach stratygraficznych w Kotlinie Sandomierskiej, na północnym przedpolu Karpat oraz Wyżynie Wołyńskiej i Podolskiej. Z uzyskanych tą drogą danych widać, jak ważną rolę należy przypisać stratygrafii lessowo-glebowej przy uściślaniu schematu stratygraficznego czwartorzędu. Całość zebranych materiałów pozwoliła na podjęcie próby korelacji głównych jednostek podziału stratygraficznego czwartorzędu zachodniej i środkowo-wschodniej Europy. Korelacja ta dowodzi wyjątkowego znaczenia SE Polski i NW Ukrainy jako obszaru, gdzie zachowały się ślady pobytu lądolodów skandynawskich w czasie 7 kolejnych zlodowaceń (od narwi do warty) oraz gdzie istnieje najlepsza możliwość korelacji tych zlodowaceń z lessami akumulowanymi zarówno w strefach brzeżnych zlodowaceń, jak też w warunkach ekstraglacjalnych.
