(2006)Ab initio calculations at 0 K have been used to predict the effect of nickel on the phase stability of the body-centred-cubic (bcc), face-centred-cubic (fcc) and hexagonal-close-packed (hcp) phases of iron. We have calculated ...
-
(2006)The natural abundance of radiocarbon (14C) provides unique insight into the source and cycling of sedimentary organic matter. Radiocarbon analysis of bacterial phospholipid lipid fatty acids (PLFAs) in salt-marsh sediments ...
-
(2006)The Nellore-Khammam Schist Belt (NKSB) in South India is a Precambrian greenstone belt sited between the Eastern Ghats Mobile Belt (EGMB) to the east and the Cratonic region to the west. The belt contains amphibolites, ...
-
(2006)Wildfire can lead to considerable hydrological and geomorphological change, both directly by weathering bedrock surfaces and changing soil structure and properties, and indirectly through the effects of changes to the soil ...
-
(2006)Melts formed by small degrees of partial melting are rich in volatiles and may reach critical supersaturation during slow ascent or due to partial crystallization. Following nucleation, the bubbles grow and, if magma volume ...
-
(2006)Stable carbon (δ13C) and hydrogen (δD) isotopic compositions of n-alkanes, anteiso-alkanes, n-alkanoic acids, n-alkanols, phytol and sterols in raw leaves of Acer argutum and Acer carpinifolium, their fallen leaves, mold ...
-
(2006)Variations in seismological structure, major element composition, and axial depth between different back-arc spreading centers provide constraints on physical conditions associated with back-arc melt production. We invert ...
-
(2006)Precise measurements of local magnetic fields have been obtained with a differentially connected array of seven synchronized proton magnetometers located along 60 km of the locked-to-creeping transition region of the San ...
-
(2006)Reaction zones around minerals in mantle xenoliths have been reported from many localities worldwide. Interpretations of the origins of these textures fall into two groups: mantle metasomatic reaction or reaction during ...
-
(2006)As an important part of the Paleozoic orogonic belt in northern Xinjiang, the Junggar is characterized by intense and extensive development of Late Paleozoic granitoid plutons together with minor mafic plutons, and it is ...

EVIDENCE OF PRECURSOR PHENOMENA IN THE KOBE EARTHQUAKE OBTAINED FROM ATMOSPHERIC RADON CONCENTRATION (2006)Atmospheric 222Rn concentrations were determined over a 10a period, which included the date of the Kobe, Japan earthquake, on January 17th 1995. It was found that the seismically related 222Rn anomaly was higher than the ...
-
(2006)Grain growth rates in partially molten olivine aggregates were determined experimentally at a pressure of 1GPa. The aim of the experiments with fine-grained starting material (solution-gelation derived Fo90 olivine with a ...
-
(2006)The deconvolution of three-component teleseismic P waves is investigated using the autocorrelation of the P to SV scattered waves, which is important for improved imaging of crustal and upper mantle structure. The SV ...
-
(2006)The Miocene to Quaternary lavas of northwestern Syria range from basanite, alkali basalts, and tholeiites to basaltic andesites, hawaiites, and mugearites. Crustal assimilation and fractional crystallization processes (AFC) ...
-
(2006)The relationships between the major terrestrial volatile reservoirs are explored by resolving the different components in the Xe isotope signatures displayed by Harding County and Caroline CO2 well gases and mid-ocean ridge ...
-
(2006)Previously published platinum group element (PGE) and rare earth element data (REE) from a sample suite of the Palaeogene flood basalts of the East Greenland rifted margin are used to approximate primary magma compositions ...
-
(2006)The variations of chemical and carbon isotopic compositions in gaseous hydrocarbons upon abiogenic oxidation by sulfates, hematite and both in laboratory studies were clearly demonstrated through a unique two-step experimental ...
-
(2006)The Hançili bentonite from Turkey shows significant changes in surface area, micro- and mesoporosity, surface acidity and acid strength with heating from 100 to 900°C for 2 h. The specific surface area (S) and specific ...
-
(2006)This work is aimed to demonstrate the feasibility of a methodology for retrieving bio-geophysical variables whilst at the same time fully accounting for additional information on directional anisotropy. A model-based ...

GEOCHEMICAL CONSTRAINTS ON THE ORIGIN OF THE PERMIAN BAIMAZHAI MAFIC-ULTRAMAFIC INTRUSION, SW CHINA (2006)The ~260 Ma Baimazhai mafic-ultramafic intrusion is considered to be part of the Emeishan large igneous province and consists of orthopyroxenite surrounded by websterite and gabbro. The intrusion is variably mineralized ...
