(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 ...
-
(2006)A new methodology for magnetic resonance sounding (MRS) data acquisition and interpretation was developed for locating water-filled karst cavities. This methodology was used to investigate the Ouysse karst system in the ...
-
(2006)This paper describes the petrology and geochemistry of high-pressure veins and associated metasomatic selvages that are hosted by eclogite in the Pouébo Eclogite Melange of northern New Caledonia. Isotopic and geochemical ...
-
(2006)The pore water chemistry of mud volcanoes from the Olimpi Mud Volcano Field and the Anaximander Mountains in the eastern Mediterranean Sea have been studied for three major purposes: (1) modes and velocities of fluid ...
-
(2006)We present petrographic and geochemical data on representative samples of the Devonian adakite, boninite, low-TiO2 and high-TiO2 basalts and associated rocks in the southern Altay areas, Xinjiang, NW China. These volcanic ...
-
(2006)The identification of compositional changes in fumarolic gases of active volcanic areas is one of the most important objectives in monitoring programmes. Together with information from seismic data and deformation, it ...
-
(2006)The Baimazhai Ni-Cu-PGE (platinum-group-elements) sulfide deposit, southeast Yunnan Province, is hosted in mafic-ultramafic intrusions of the Permian Emeishan large igneous province, with which it is temporally and genetically ...
-
(2006)The aim of this study is threefold: (1) to evaluate the effect of the physical properties of weathered granitic material (geometry and spatial distribution of hydraulic conductivity) on water fluxes at the outlets of two ...
-
(2006)We develop a new class of absorbing boundary conditions (ABCs) to prevent unwanted artifacts and wraparounds associated with aperture truncation in migration/modeling using high-order, one-way wave equations. The fundamental ...
-
(2006)An important result of the Mars Exploration Rover's (MER) mission has been the images of sedimentary structures and diagenetic features in the Burns Formation at Meridiani Planum. Bedding, cross-bedding, ripple marks, mud ...
-
(2006)Gypsum dunes at White Sands National Monument, New Mexico, provide an excellent analog to sulfate-rich eolian outcrops on Meridiani Planum, Mars, as characterized by the Rover Opportunity. Numerous outcrops imaged by ...
