-
(2006)Benthic foraminiferal tests of a sediment core from southwestern Skagerrak (northeastern North Sea, 420 m water depth) were investigated for their ratio of stable oxygen isotopes. During modern times sudden drops in ...
-
(2006)Allanite-(La) is a member of the epidote group. It was sampled at Buca della Vena mine, near Stazzema, Apuan Alps, Tuscany, Italy. It occurs as Prismatic crystal up to 2-3 mm in length along [010] within barite veins cutting ...
-
(2006)Twenty-two samples of allanite-(Ce) taken from granitic rocks in Japan have been characterized by electron-microprobe analysis. In back-scattered-electron (BSE) images, the allanite-(Ce) is homogeneous or characterized by ...
-
(2006)Bromalites from the Soom Shale are allocated to five main categories on the basis of shape, content and internal structure: those containing broken conodont elements; those containing brachiopod fragments; corrugated/spiral ...
-
(2006)The Masoko maar (southern Tanzania) provides one of the most continuous Late Quaternary lacustrine sedimentary records from Africa. A detailed chronostratigraphic framework coupled with sedimentological and magnetic ...
-
(2006)Experiments using synthetic mafic liquids of composition Fo30Di30An40 and Fo22Di58An20 (wt.%) were conducted to constrain the range of cooling regimes over which melt inclusions form in olivine crystals. In one set of ...
-
(2006)Tropical monsoons are key mechanisms for transfer of heat and moisture to higher latitudes. Here we present a high-resolution, terrestrial proxy summer monsoon record for the southeast Asian monsoon, from a rapidly ...
-
(2006)Metals play important but varied roles in human health. Some metals are required for normal metabolic function, with optimal amounts for maximum benefit. Others are only known to cause toxic effects. Most of our knowledge ...
-
(2006)Charcoal preserved in accretionary loess-soil profiles within the southern part of the Loess Plateau has recorded fire history and landscape evolution connected with climatic variations and human activities. Local wildfires ...
-
(2006)The chronological record of the woolly mammoth (Mammuthus primigenius) in Japan is reevaluated on the basis of new and previously published radiocarbon dates obtained from 9 of the 11 known specimens. The dates range from ...
-
(2006)A combined study of geochronology and geochemistry was carried out for Neoproterozoic granodiorites at the southeastern margin of the Yangtze Block in South China. The results demonstrate that sedimentary rocks derived ...
-
THE MAGMATIC EVOLUTION OF THE LAND'S END PLUTON, CORNWALL, AND ASSOCIATED PRE-ENRICHMENT OF METALS (2006)The peraluminous Land's End granite is one of the composite plutons forming the late-Variscan Cornubian batholith. The western part of the pluton hosts the Sn-Cu mineralisation of the St. Just mining district. The pluton ...
-
(2006)This paper reports a new 1° × 1° global thermal model for the continental lithosphere (TC1). Geotherms for continental terranes of different ages (> 3.6 Ga to present) constrained by reliable data on borehole heat flow ...
-
(2006)Solid solutions within the system Co-Fe-Ni-P were studied experimentally at 800 degrees C by means of the evacuated silica tube technique. Three broad sol id-solution series were detected in the system, tetragonal phi, ...
-
(2006)The Iti and Kallidromon ophiolites, in continental central Greece, consist mainly of an ophiolite melange overthrust by variably serpentinized ultramafic rocks. They include lherzolite and harzburgite; dunite pods occur ...
-
(2006)A 10 m sediment core from Academician Ridge in Lake Baikal was analyzed for its molecular composition using on-line TMAH (tetramethylammomium hydroxide) thermochemolysis. Major products are lignin phenols, n-C14 to C30 ...
-
(2006)As with modern organisms, the spatial and temporal distribution of fossil communities was controlled by both the physical setting in which the organisms lived and by the organisms' physiology and interactions. By studying ...
-
(2006)Seven peat and 40 dead wood remains (mountain birch) were sampled within and above the present treeline ecotone on two mountains (Rodjanoaivi, Koahppeloaivi/Staloskaidi) along the Tenojoki in northernmost Finnish Lapland. ...
-
(2006)Stable carbon and oxygen isotope analyses were conducted on pedogenic carbonates collected from a continuous, late Neogene terrestrial sequence located in Lantian, in the Chinese Loess Plateau. The sequence consists of 300 ...
-
(2006)A 12 m loess–paleosol section (La Angostura) from Tafi del Valle, Tucumán, Argentina was studied using rock magnetic measurements, geochemistry, Mössbauer effect, particle size and Nd isotopes in order to elucidate changes ...
