The Bai-u season was reconstructed with the aid of weather records entered in old diaries between the beginning of the eighteenth century and 1895. The duration of the Bai-u season revealed a strong positive correlation with the end of the Bai-u

The Dead Sea is surrounded by chemical and detrital sediments that where deposited in its larger precursor lakes, Lake Samra and Lake Lisan. The sedimentary history of these lakes was reconstructed by means of 230Th/234 U ages of 30 samples

The ice-rich permafrost deposits on the coastal lowland in northeastern Siberia and on the New Siberian Islands often contain layers, lenses, and inclusions of peat that are too old to be dated by AMS. Application of 230 Th/U disequilibrium dating

This paper reports U-series dates on speleothem samples from Localty 15 at Zhoukoudian, one of the richest Paleolithic sites in northern China. The AA discuss their implications for human physical and cultural evolution. The results are in line
Amino acid enantiomeric (D/L) ratios in the mollusk Mercenaria are compared with recently published biostratigraphic and/or U-series solitary coral data from 22 Quaternary localities on the central and southern Atlantic Coastal Plain. In all cases
, local relative aminostratigraphic sequences are consistent with relative ages inferred from U-series or biostratigraphic data, although occasionally more depositional events are recognized by aminostratigraphic than biostratigraphic methods. However
, if the U-series data are used as age calibrations for the D/L values, latitudinal trends of isochronous D/L values are highly variable and conflict with trends expected from the present temperature gradient.
The spatial reorganization of office functions by rationalization : a case study of the large-scale retailer U N Y
This study aims to clarify how one Japanese corporation (large scale retailer U N Y ) rationalized and changed the spatial organization of its office functions during this recession. - (KA)
The different methods of datation using the uranium series are described: Th/U, Pa/U, U/He as well as the methods of determining the sedimentation rates: Th, Th/Th, Pa and Pa/Th. The different materials on which they can be applied are reviewed
U-series analyses of the lower Travertine at Ehringsdorf, DDR
U-series analyses have been made of travertine samples from the archaeological site at Ehringsdorf-Weimar. The lower Travertine, in which hominid remains were found, yields apparent ages from > 350,000 to 200,000 yr.
Geochemical and mineralogical behavior of REE, Th and U in the Akongo lateritic profile (SW Cameroon)
The aim of this study is to determine the behavior of REE, U and Th during the weathering of a crystalline rock with common REE-U-Th contents. The Akongo lateritic profile which developed on a syenite has been chosen because 1) this profile
Cette étude des concrétions calcaires des varves de Deschaillons a permis, outre l'établissement de l'âge absolu de celles-ci, d'examiner les limites d'applicabilité de la méthode du déséquilibre radioactif Th/U à la datation de carbonates contenant
Discussion des six âges U-Pb sur zircons obtenus pour les roches de cette région. Comparaison de ces déterminations chronologiques avec celles rapportées pour les ceintures adjacentes de Michipicoten et Gamitagama.
U-series dating by the TIMS technique of land snails from paleosols in the Canary Islands
A sequence of seven superimposed paleosols developed on eolian calcarenites and alluvium was sampled on the island of Lanzarote in order to examine the possibility of dating land snail shells by the U-series method, using a TIMS technique allowing
measurement of U and Th isotopes in very small samples.
