-
(2006)Hydrothermal vein minerals directly associated with native gold mineralization in the Muruntau vein system (Uzbekistan) have been studied for noble gas, carbon isotope and halogen chemistry of the trapped ore-related fluids. ...
-
(2006)By using orthogonal regression method, a systematic comparison is made between surface wave magnitudes determined by Institute of Geophysics of China Earthquake Administration (IGCEA) and National Earthquake Information ...
-
(2006)Aiming at two Dayao earthquakes with magnitude more than 6 occurred in 2003 in Yunnan Province, we analyzed and interpreted the NOAA satellite thermal infrared images of 1999, 2003 and 2004 in Chuandian region, and also ...
-
(2006)The data of Bouguer gravity and topography are inverted to obtain the crust thickness of China. In order to reduce the effect of regional non-isostasy we corrected the reference Moho depth in the inversion with regional ...
-
(2006)Here, we present new measurements of 32S, 33S, 34S, and 36S in sedimentary sulfides and couple these measurements with modeling treatments to study the sulfur cycle of a late Paleoproterozoic marine basin. We target the ...
-
(2006)We report a discovery of an ophiolite mélange in Taerbahatai Mts. (Xinjiang, NW China), which underlies the Early Carboniferous Heishantou Group consisting mainly of mudstone, siltstone, tuff, alloclastic rocks, volcanic ...
-
OS ISOTOPE SYSTEMATICS OF OS-RICH ALLOYS AND SULFIDES FROM CONTINENTAL AND OCEANIC MANTLE: NEW DATA (2006)The advantage of the Re-Os system, applied to Os-rich platinum-goup minerals (PGMs), is that PGMs contain Os as a main or trace element, while at the same time almost lack Re. Consequently, primary Os-rich PGMs (e.g., ...
-
(2006)X-band electron paramagnetic resonance (EPR) spectra of gamma-irradiated crystals of carbonate-bearing fluorapatite from the Levant mine, Cornwall, England, revealed the presence of two previously characterized centers ...
-
(2006)Mössbauer spectroscopy, H2O, and microprobe analysis techniques have been used to study upper mantle ferrikaersutite megacrysts from the scoria cones of the Ash Sham alkaline volcanic field, northeastern part of the Arabian ...
-
(2006)Olivines in spinel-peridotite mantle xenoliths from Simcoe (Washington State, USA) and Mexico were analyzed by Fourier-transform infrared spectrometry (FTIR) to determine their water contents. The main OH absorbance peaks ...
-
(2006)In order to investigate the partitioning of trace elements in mineral phases of black shales and diagenetic remobilization of trace elements within these phases, we isolated major black shale components (sulfide, carbonate, ...
-
(2006)Time-of-flight powder neutron diffraction has been used to measure the molar volume of MgSO4.7D2O (i) from 1.8 - 300 K at ambient pressure, (ii) from 50 - 290 K at 1.4, 3.0, and 4.5 kbar, (iii) from 0 - 5.5 kbar at 290 K, ...
-
GLACIAL AND ROCKY-SHORE DYNAMICS OF THE KARLEBOTN MONADNOCKS: LATE NEOPROTEROZOIC OF NORTHERN NORWAY (2006)Located near the village of Karlebotn in East Finnmark, Norway, a cluster of six gneissic monadnocks is unconformably surrounded by weakly metamorphosed sandstone strata of late Neoproterozoic age in the Smalfjord Formation. ...
-
(2006)A new concept gravity meter with sensitivity close to 10-8ms-2/√Hz in the range of 10-5-1 Hz intended for observation of the vertical component of the Earth gravity and teleseismic waves was implemented at the Istituto di ...
-
(2006)A compositionally diverse group of basaltic flows are present in the 2.7 Ga St. Joseph assemblage of the St. Joseph greenstone belt, Uchi Subprovince. A spectrum of light rare earth element (LREE) depleted to enriched ...
-
(2006)Fluorite is the most common fluoride mineral in magmatic silicic systems and its crystallization can moderate or buffer fluorine concentrations in these settings. We have experimentally determined fluorite solubility and ...
-
(2006)The layer charge reduction of two Li-saturated montmorillonites is referred to application of microwave radiation at 2.45 GHz for dispersions and 30.0 GHz for the solid powders. Efficiency of these treatments was compared ...
-
(2006)The peridotite bodies of the Ulten Zone (Upper Austroalpine, Italian Eastern Alps) are enclosed in Variscan migmatites and derive from a mantle wedge environment. They display the progressive transformation of porphyroclastic ...
-
(2006)The dual-thermodynamic (DualTh) approach is shown to provide a useful alternative to other methods in: (i) forward modelling of equilibrium speciation, activities, and element partitioning in a heterogeneous system involving ...
-
(2006)Unlike many other characteristics that affect the clarity grade of a diamond, determination of the impact of "whitish" graining and "reflective" graining requires analysis that goes beyond visibility at 10× magnification. ...
