-
(1998)The first osmium isotope data are presented for marine sediments spanning the past 200,000 years (two full glacial cycles) and establish that there have been ocean-wide variations in sea-water osmium isotope composition ...
-
(2001)The elements of many conodont taxa exhibit a polygonal surface micro-ornamentation. Four main types are recognized (striation, linear texture, regular (idiomorphic) texture and granular texture) and their distribution over ...
-
(1987)The authors present their analysis of new strontium-isotope data on 88 volcanic rock samples from the KIA (Kurile Island Arc) and on 10 from the Ksudach volcano, southern Kamchatka. The strontium-isotope ratios were measured ...
-
(2000)Variations in sediment input and distribution to the Laptev Sea continental margin during the Holocene and Termination I could be identified based on radiocarbon dated magnetic susceptibility logs and sediment thickness ...
-
(2006)Variations of Eu/Eu* ratio in shales from the upper Vendian Kairovo and Shkapovo groups of the Shkapovo-Shikhan depression, the Volga-Ural region, are considered. Shales in the lower part of the Karlin Formation are ...

VARIATIONS OF SELF-POTENTIAL AND UNSATURATED WATER FLOW WITH TIME IN SANDY LOAM AND CLAY LOAM SOILS (2002)Accurate assessment of soil-water fluxes is essential in soil physics due to its direct implications in environmental, agronomical or hydrological applications. Field estimations of soil-water fluxes by 'classical' hydraulic ...
-
(2004)In order to examine the variations of terrigenous detrital components in the core (97PC-19) sediments from the southern margin of the Ulleung Basin, we detail changes in grainsize composition and contents of major elements ...
-
(2003)The Ca isotope variation of 11 Miocene and Pleistocene, authigenic, marine phosphates is rather small compared to the corresponding variation in δ18O values. The δ44Ca values are not correlated with the δ18O values and, ...
-
(2001)The earthquakes of various magnitudes (M ≥ 7.0, 4.0 ≤ M < 7.0) for the period from 1977 to 1998 are considered. A different recurrence of the number of strong and weak earthquakes is revealed. Variations of sunspot numbers, ...
-
(1998)This study is concerned with the response of high frequency seismic noise (HFSN) to earth tide, namely, to one of its components, the tidal wave O1 (of period 25.8 hours), which is taken to be a reference effect. Three-year ...
-
(2002)The Variscan Belt of western Europe is part of a large Paleozoic mountain belt, 1000 km wide and 8000 km long, that extended in Permian time from the Caucasus and Urals in Europe to the Appalachian and Ouachita Mountains ...

-
(2001)New pollen records and radiocarbon dates from two sites in the Yana River lowlands, Arctic Yakutia, Russia provide reconstruc-tions of vegetation and climate history of this region during the last 6400 yr. The #uctuations ...
-
(PANGAEA, 2010-06-08)
-
(PANGAEA, 2014-11-05)The last glacial-interglacial transition or Termination I (T I) is well documented in the Black Sea, whereas little is known about climate and environmental dynamics during the penultimate Termination (T II). Here we present ...
