Eustatic sea-level and climate changes over the last 600 ka as derived from mollusc-based ESR-chronostratigraphy and pollen evidence in Northern Eurasia, 2002, Molodkov Anatoly N. , Bolikhovskaya Nataliya S. ,
We reconstruct and correlate palaeoclimatic events and deposits from shelf, glacial, periglacial, and extraglacial zones of northern Eurasia over the last 600,000 years. The chronostratigraphical correlation of identified palaeoenvironmental and sea-level events and corresponding horizons is based on electron spin resonance (ESR) analysis of subfossil mollusc skeletal remains from marine, freshwater and Acheulian-bearing cave-site deposits. Over 230 shell samples from more than 40 sites along the continental margin of Eurasian north, in the Black and Caspian sea basins and terrestrial shells from a Lower Palaeolithic cave-site in the Northern Caucasus were dated via ESR to produce a late Quaternary geochronology. The Pleistocene composite section of the loess-palaeosoil formation includes two reference sections--Likhvin and Arapovichi--from the centre of the East-European plain. The palyno-chronostratigraphic record is interpreted as the product of six warm-climate/high sea-level events including the current interglacial, and six glacial events. They are presented either as complete climatic rhythms of glacial and interglacial rank, or by considerable portions of climatic-phytocoenotic phases constituents of the rhythm. The full-interglacial conditions are centred at about 580, 400, 310, 220 and between 145-70 calendar ka. A broad correspondence between long palynological sequence, directly ESR-dated warm-climate-related events and other palaeoenvironmental records described in the literature has been noted for 11 upper oxygen isotope stages (11 to 1). The results obtained in this study exemplify the potential of integrated chrono-climatostratigraphic sequences in linking marine and terrestrial palaeoclimate records that may eventually span the whole Brunhes chron

Uranium series dates from Qesem Cave, Israel, and the end of the Lower Palaeolithic, 2003, Barkai, R. , Gopher, A. , Lauritzen, S. E. , And Frumkin, A.
Israel is part of a geographical ?out of Africa? corridor for human dispersals. An important event in these dispersals was the possible arrival of anatomically modern humans in the Levant during the late Middle Pleistocene1,2,3. In the Levant the Lower Paleolithic ends with the Acheulo-Yabrudian complex, characterized by striking technological developments4,5 including the introduction of advanced technological innovations such as systematic blade production and the disappearance of hand-axes . These reflect new human perceptions and capabilities in lithic technology and tool function, as well as innovative human adaptation6. Qesem Cave, discovered in 2000, has a rich, well-preserved Acheulo-Yabrudian sequence holding great promise for providing new insights into the period. Here we report the dates of this cave obtained by U-series of speleothems and their implications. The results shed light on the temporal range of the Acheulo-Yabrudian and the end of the Lower Paleolithic, suggesting a long and unique cultural phase between the Lower Paleolithic Acheulian and the Middle Paleolithic Mousterian, starting well before 350 kyr and ending at ca. 200 kyr.

Pleistocene depositional history in a periglacial terrane: A 500ka record from Kents Cavern, Devon, United Kingdom., 2007, Lundberg, J. And Mcfarlane, D. A.
The signifi cance of the stratigraphic record in Kents Cavern, Devon, United Kingdom, to the interpretation of the British Quaternary is confi rmed on the basis of a thorough reexamination of the deposits in concert with 2 new Al-Be cosmogenic and 34 new thermal ionization mass spectrometry U-Th dates. The deposits show evidence of complex reworking in response to periglaciation, and the main fl owstone deposit is a multilayered complex spanning marine isotope stage (MIS) 11?3. The lowermost unit of fl uvial sands is Cromerian or older. The second deposit, a muddy breccia of surfi cial periglacial solifl uction material containing Acheulian artifacts, entered the cave during MIS 12 from highlevel openings to the west. Cave bears denned in the cave during MIS 11, the Hoxnian interglacial; their bones are capped by an MIS 11 calcite fl owstone layer. From MIS 11 onward, each interglacial period and the warmer interstadial periods (MIS 11, 10b, 9, 7, 6b, 5, and 3) produced calcite fl owstone deposition in the cave; MIS 9 was particularly active. Each glacial or stadial period (MIS 10c, 10a, 8, 6c, 6a, 4, and 2) caused periglacial activity in the cave, during which the thinner layers of calcite were fractured by frost heave and redistributed by solifl uction. This sequence was interrupted during MIS 3?2 with the introduction of sandy and stony clastic sediments from entrances to the east, and fi nally cemented by the uppermost layer of MIS 1 fl owstone. This is the fi rst publication of welldated and clearly documented evidence of frost heaving in interior cave passages. The Kents Cavern record of continuous, repeated sedimentation events followed by frost shattering and remobilization events over the past 500 k.y. is probably unique in the karst literature and establishes Kents Cavern as a site of international scientifi c interest.
