-
(2006)Microstructural and petrological analysis of samples with increasing strain in high-pressure (HP) shear zones from the Haram garnet corona gabbro give insights into the deformation mechanisms of minerals, rheological ...
-
(2006)Analysis of seismic data suggests that hydrocarbon deposits are often associated with higher than usual values of attenuation, but this is generally ignored during amplitude-versus-offset (AVO) analysis. The effect can be ...
-
(2006)Due to the Earth's inhomogeneity, seismogram envelopes increase in duration and decrease in amplitude with increasing travel distance. Those features have been explained on the basis of the forward scattering in random ...
-
(2006)The low-temperature heat capacities for a series of synthetic garnets along the pyrope-grossular (Py-Gr) join were measured with the heat capacity option of the Physical Properties Measurement System (PPMS) produced by ...
-
(2006)Monthly (or bi-weekly) water samples were collected from the Yukon River, one of the largest rivers in North America, at a station near the US Geological Survey Stevens Village hydrological station, Alaska from May to ...
-
(2006)Allanpringite is a new ferric iron phosphate with the ideal formula Fe3(PO4)2(OH)3 ·5H2O, and is closely related to wavellite, Al3(PO4)2(OH)3 ·5H2O. Type locality is the dump of the abandoned Grube Mark near Essershausen, ...
-
(2006)Whole rock major and trace element abundances in aluminous garnet-spinel websterite, sapphirine-bearing Mg-Al granulite and hibonite-bearing Ca-Al granulite xenoliths from the Chyulu Hills volcanic field, Kenya, suggest ...
-
(2006)The Chi-Chi, Taiwan, earthquake of 20 September 1999 was preceded by a notable decrease of the regional seismicity rate. The anomalous period started in January 1999 and lasted about 9 months, up to the occurrence of the ...
-
(2006)Lunar impact melt breccias provide a unique record of the timing and frequency of collisional events during the early history of the inner Solar System prior to the development of a significant rock record on Earth. The ...
-
(2006)To date, all Cretaceous ichthyosaur material from North America has been referred to the species Platypterygius americanus. This species is generally identified based on skull and paddle morphology, but all non-diagnostic ...
-
(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 ...
