(2006)High-resolution magnetic analysis has been performed on the top ~25 m of core MD99-2275 (66°33.06′N, 17°41.59′W; 440 m water depth) from the mid-outer shelf off North Iceland. This is a key boundary region for climate ...
-
(2006)Carbon dioxide emissions and heat flow through soil, steam vents and fractures, and steam heated mud pools were determined in the Reykjanes geothermal area, SW Iceland. Soil diffuse degassing of CO2 was quantified by soil ...
-
(2006)The petrology and geochemistry of serpentinized harzburgites within the Feather River Ophiolite in northern California were investigated to constrain the origin of serpentinization. Trace-element systematics indicate that ...
-
(2006)The pressure-temperature conditions of the reactions of the double carbonates CaM(CO3)2, where M = Mg (dolomite), Fe (ankerite) and Mn (kutnohorite), to MCO3 plus CaCO3 (aragonite) have been investigated at 5-8 GPa, ...
-
(2006)The association of anomalous topographic swells and widespread Cenozoic volcanism within the African plate (Hoggar, Tibesti, Darfur, Ethiopian highlands, Kenyan dome) may reflect either the involvement of one, or several, ...
-
(2006)The structural and geodynamic history of the Malopolska Massif (Holy Cross Mountains - Poland), situated within the Trans-European Suture Zone (TESZ) is still a matter of debate. Recent provenance studies and biogeographical ...
-
(2006)The release of Zr, U, and Pb from nearly metamict zircon and its recrystallized analog and of Zr from fully crystalline and slightly radiation-damaged zircon in H2O+ HCl ± SiO2 fluids was investigated in situ at temperatures ...
-
(2006)The discovery of the giant Geode of Pulpí (Almería, Spain) was considered as an important highlight in the geological heritage of Spain. Projects developed for their conservation were immediately initiated with legal figures ...
-
(2006)The 2.68 Ga Phantom Lake metamorphic suite of the Sierra Madre is a volcanogenic, volcaniclastic, and siliciclastic sequence that may have been deposited on or near the margin of the Wyoming Province or, alternatively, it ...
-
(2006)Historical land use changes may have significant impact on erosion and agricultural soil properties, including soil degradation by acidification, nutrient leaching and organic matter depletion. The Kali Basin study area, ...
-
(2006)Bubble gas samples were collected at three different vegetation sites and two different depths (surface and 40 cm) in a natural wetland, Mizorogaike in Kyoto city, to investigate hydrogen concentration and δD and δ13C ...
-
(2006)The well-studied Paleozoic Cooma metamorphic complex in southeastern Australia is characterized by a uniform siliciclastic protolith, of uniform age, with a continuous range of metamorphic grade from subgreenschist- to ...
-
(2006)As part of a comprehensive crystal-chemical study and classification of minerals and synthetic compounds with kröhnkite-type or -like chains of octahedra bridged by tetrahedra, the crystal structures of wendwilsonite from ...
-
THE MAGNESIUM ISOTOPE BUDGET OF THE MODERN OCEAN: CONSTRAINTS FROM RIVERINE MAGNESIUM ISOTOPE RATIOS (2006)We have measured the magnesium (Mg) isotope ratios in 45 rivers including 16 of the largest rivers in the world, covering a range of geologic, tectonic and climatic drainage basin environments. The range in riverine δ26Mg ...
-
(2006)The structure and mechanism of cation sorption at the (0 0 1) muscovite-water interface were investigated in 0.01 and 0.5 m KCl, CsCl, and CaCl2 and 0.01 m BaCl2 solutions at slightly acidic pH by high-resolution X-ray ...
-
(2006)We present detailed experimental results on the partitioning of rare earth elements (REE) between titanite and a range of different silicate melts. Our results show that Henry's law of trace element partitioning depends ...
-
(2006)Major, trace (Y, Zr, Pb, Th and U), rare earth element (REE) and Sm-Nd isotope analyses were carried out on microbialites and detrital carbonate sediments collected in Upper Jurassic coral- and sponge-microbialite reef ...
-
(2006)Oxidation of pyrite by hydrogen peroxide (H2O2) at millimolar levels has been studied from 4 to 150 °C in order to evaluate isotopic effects potentially associated with radiolytic oxidation of pyrite. Gaseous, aqueous, and ...
-
(2006)Large-scale asymmetries in structures, and in the uplift, width and volcanism of pairs of conjugate passive margins have been documented in various parts of the world; these asymmetries reflect the dominant mode of extension ...
-
(2006)Global analyses of 88 families and 284 genera of brachiopods from middle Ashgill, Late Ordovician, to early-middle Rhuddanian, Early Silurian, indicate that 18.6% and 12.5% of families and 51.0% and 41.3% of genera were ...
