-
(2006)High seismic Vp velocity anomalies (8.7-9.0 km s- 1) have long been known about in regions of the uppermost mantle of the Siberian craton, often in association with kimberlite fields. Laboratory measurement of seismic ...
-
(2006)Present-day relations between small-mammal community structure and rainfall are used to predict late Neogene (12-3 Ma) precipitation patterns in Europe and Anatolia. New proxy methods are developed which include regressions ...
-
(2006)As noted elsewhere in this volume, research on sulfide mineral surfaces and surface reactivity is a relatively recent concern of mineralogists and geochemists, partly prompted by the availability of new imaging and ...
-
(2006)Neoarchaean plutonism in the Kuhmo district in eastern Finland, Karelia, includes tonalites, sanukitoids, leucocratic granodiorites, and leucogranites. A U-Pb (SIMS and TIMS) study of zircons and titanites places age ...
-
(2006)The solubility and incorporation mechanisms of hydrogen in synthetic stishovite as a function of Al2O3 content have been investigated. Mechanisms for H incorporation in stishovite are more complex than previously thought. ...
-
(2006)There can be no disputing the fact that neutron diffraction and scattering have made a clear contribution to our current understanding of the structural and dynamical characteristics of liquid water and water containing ...
-
FUNCTIONAL AND EVOLUTIONRY ASPECT OF THE POSTCRANIAL ANATOMY OF DICYNODONTS (SYNAPSIDA, THERAPSIDA) (2006)Restoration of the major skeletal muscles and functional morphological analysis of the postcranium were carried out on two Triassic dicynodont genera, Wadiasaurus and Lystrosaurus. A phylogenetic analysis of 12 selected ...
-
(2006)Sedimentological and geochemical (XRF) data together with information from diatom and benthic foraminiferal records of a 3.5 m long gravity core from Ameralik Fjord, southern West Greenland, is used for reconstructing ...
-
(2006)The Tuwu copper deposit, located in the Dananhu-Tousuquan island arc between the Kazakhstan-Junggar and Tarim plates, is one of the largest porphyry copper deposits in western China. Ore-hosting rocks consist of Early ...
-
(2006)A new genus and species of gempylid is described from the Late Miocene (Messinian) diatomite deposits of the Chelif Basin, north-east Algeria. Although its skeleton is incomplete, Chelifichthys goujeti gen. et sp. nov. ...
-
(2006)The results of ~4000 LA-lCP-MS analyses in 152 thin sections from common crustal rocks reveal that several rock-forming minerals contain tens to a few thousand ppm of Zr. The highest concentrations of Zr are found in ...
-
(2006)Platinum group mineral (PGM) assemblages in the Platreef at Sandsloot, northern Bushveld Complex, in a variety of lithologies reveal a complex multi-stage mineralization history. During crystallization of the Platreef ...
-
(2006)The Caledonian Orogen in Arctic Norway is characterized by a variety of nappes thrust from west to east onto the Baltic Shield. Traditionally, this has been regarded as the product of two orogenic events: an earlier ...
-
(2006)Twenty-two terrestrial and over 20 marine mammal faunas are currently recognized in the fossil record of Victoria, representing one of the most complete records of mammal evolution in Australia. Although the earliest ...
-
(2006)The examination of production history from hydrocarbon fields composed of turbidite deposits indicates that fluid flow behaviour is often more complex than expected. The cause is commonly linked to the presence of fine-scale ...
-
(2006)The past twenty years or so have seen dramatic development of the experimental and theoretical tools available to study the surfaces of solids at the molecular (?atomic resolution?) scale. On the experimental side, two ...
-
(2006)We investigated the distributions and δ13C values of lipid biomarkers in authigenic methane-related carbonate crusts formed on eastern Mediterranean mud volcanoes. A highly diverse suite of microbial membrane lipids was ...
-
(2006)Carbonate units of the Chocolay Group in the Lake Superior area, USA and the Gordon Lake Formation of the correlative upper Huronian Supergroup, Ontario, Canada were deposited after the last Paleoproterozoic glacial event ...
-
(2006)Measurement of magnetic susceptibility (MS) and diffuse reflectance spectra (DRS) were used to construct environmental proxies in a 6.5 m section of the sediment core VER98-1-13 from the Academician Ridge, Lake Baikal. The ...
-
(2006)Midge remains (Insecta: Diptera: Chironomidae and Chaoboridae) from two upland lake basins on the Cumberland Peninsula of Baffin Island were analyzed and the results used in a transfer function to reconstruct paleotemperatures. ...
