(2006)The concentrations of the fluid mobile trace elements lithium, beryllium, boron, and barium were measured in samples of the altered matrix of several impactite breccias of the Yaxcopoil-1 drill core using secondary ion ...
-
(2006)Five specimens of the priapulid Maotianshania cylindrica preserved inside their lined burrows were described from the Lower Cambrian Chengjiang deposits near Kunming, southern China. The exceptional preservation suggests ...
-
(2006)Here new mineralogical data is presented on the occurrence of K-feldspar in granulite-facies metagabbronorite xenoliths found in recent alkaline lavas from Western Sardinia, Italy. The xenoliths originated from the ...
-
(2006)To ascertain the progressive stages of shock metamorphism of zircon, samples from three well-studied impact craters were analyzed by optical microscopy, scanning electron microscopy (SEM), and Raman spectroscopy in thin ...
-
(2006)The 2.55-2.50 Ga Zunhua and Wutaishan belts within the central orogenic belt of the North China craton contain variably metamorphosed and deformed tectonic blocks of peridotites and amphibolites that occur in a sheared ...
-
(2006)Quantitative dynamics of a nonwetting ganglion of residual oil entrapped in a pore constriction and subjected to vibrations of the pore wall can be approximated by the equation of motion of an oscillator moving under the ...
-
(2006)A localized dehydration zone, Söndrum stone quarry, Halmstad, SW Sweden, consists of a central, 1 m wide granitic pegmatoid dyke, on either side of which extends a 2.5-3 m wide dehydration zone (650-700°C; 800MPa; ...
-
(2006)Vascular-plant hosts, their arthropod herbivores, and associated functional feeding groups are distributed spatiotemporally into four major herbivore expansions during the past 420 m.y. They are: (1) a Late Silurian to ...
-
(2006)To determine the regional shear wave velocities in the lithosphere it is frequently necessary to use two-station dispersion curves. We investigate the influence of non-plane wave energy on such dispersion curves, and compare ...
-
(2006)Lateral variations of seismic anisotropy investigated by body waves allow us to detect the Archean - Proterozoic boundary in the upper mantle beneath the south-eastern Fennoscandia, though isotropic P-velocity perturbations ...
-
(2006)The stratabound Platinova Au-Pd Reef in the Skaergaard Intrusion is intimately linked to Cu-Fe sulphide minerals and occurs at a level that shows changes in the sulphur concentration and the Cu/S ratio. These features ...
-
(2006)The MW = 7.4 earthquake that affected the northwestern part of Turkey on August 17, 1999, and in particular the gulf of İzmit, had dramatic consequences also as regards tsunami generation. The main cause of the earthquake ...
-
(2006)We introduce a procedure for including the attenuation factor Q in a consistent manner in seismic modeling and show 3D examples. The Q fitting over a chosen frequency band involves two algorithms: The first creates starting ...
-
(2006)A challenge in the quest to understand the sensitivity of the climate system is the separation of the competing effects of ice volume or sea level, salinity, and temperature on foraminiferal δ18O. We present precipitation ...
-
(2006)Angrites are generally believed to be fragments of a basaltic asteroid that differentiated under relatively oxidizing conditions. Almost all angrites (e.g., D'Orbigny, Lewis Cliff [LEW] 86010, and Sahara 99555) are composed ...
-
(2006)Three lithostratigraphic units have been distinguished in the volcanic succession of the basal complex of Fuerteventura Island. These units are, from bottom to top: the submarine volcanic group, the transitional volcanic ...
-
(2006)New radiocarbon and optical dates show that the Holocene Danube delta started to build out of a Black Sea embayment ~5200 yr ago. Delta lobe development phases differ by as much as 5 k.y. from previously proposed ages. The ...
-
(2006)This paper presents new data on the Alpine high-pressure evolution of the Lanzo peridotite massif and its metasedimentary cover (Western Alps). Field relations in the northwestern Lanzo massif show that the serpentinized ...
-
(2006)This study of the Çameli Basin presents a detailed basin evolution combined with structural analysis and provides the first detailed time-stratigraphic framework for the neotectonic development of Neogene grabens along the ...
-
(2006)We solve the inverse magnetic problem for the depth and shape of simple sources in the presence of a regional field and truly random noise. We do not use noise-generating derivatives nor are we forced to solve complex ...
