U – PB SHRIMP DATING OF ZIRCONS FROM THE ORE-BEARING KHARAELAKH INTRUSION (TALNAKH DISTRICT, RUSSIA) (2006)World-class platinum-group-element (PGE)-Cu–Ni Oktyabr’skoe deposit closely linked to the Kharaelakh ultramafic–mafic intrusion is located in the northwestern corner of the Siberian Craton, Russia. In spite of its significant ...
-
(2006)Two smectitic Tunisian clays were organically modified by exchange reaction with dioctadecyl dimethylammonium chloride (DODMA) and hexadecyl benzyl dimethylammonium chloride (HBDMA). The resulting organoclays were used in ...
-
(2006)Knowledge about the residence time of lead in the organic horizon (mor layer; O-horizon) overlaying forest mineral soils is important for the prediction of past and future lead levels in the boreal environment. To estimate ...
-
(2006)Scholars in many fields have been focused on the west of Ordos basin for long time because of its special tectonic location and the best anthracite at Rujigou mining area Ningxia. Beginning with areal geologic background, ...
-
(2006)Some experiments on June 8, 2004, the day of transit of Venus across the Sun, were undertaken at Kolkata (latitude: 22°34′N) to observe the effect, if any, of transit of Venus on FWF, ELF and VLF amplitudes. The result ...
-
(2006)Clay minerals are low cost materials that can be structurally modified and exploited for removal of natural organic matter from freshwaters. The present study shows that vermiculites modified by ion exchange with ...
-
(2006)Analysis of strong-motion instrument recordings in Seattle, Washington, resulting from the 2002 Mw 7.9 Denali, Alaska, earthquake reveals that amplification in the 0.2-to 1.0-Hz frequency band is largely governed by the ...
-
(2006)The analyzed "menilite facies" (Early Oligocene Lower Menilites of the Tarcǎu Nappe, Romanian Carpathians, formed by "bedded cherts" and black shale-like deposits), document the upward evolution of a mainly turbiditic ...
-
(2006)What can be learned about absolute site effects on ground motions, with no geotechnical information available, in a very poorly instrumented region? In addition, can reliable source spectra be computed at a temporary ...
-
(2006)Hopanoids have been widely used as characteristic biomarkers to study inputs of bacterial biomass to sediments because they are preserved in the geologic record. A limited number of studies have been performed on hopanoid ...
-
(2006)Our specimen of the cultured Emiliania huxleyi strain (CCMP1742, also known as NEPCC55a) that provides the benchmark for U37 K′-based paleothermometry has started producing, for reasons yet unclear, major amounts of three ...
-
(2006)Sawuer region is located in west Junggar, Jimunai County of Altay district and Hefeng county of Tacheng district, Xinjiang province. The region is along the north margin of Kazakstan-Junggar plate. The post-collisional ...
-
(2006)The Carboniferous volcanic rocks occurring in western Tianshan Mountains range continuously from basalt, basaltic trachyandesite, trachyandesite, trachyte, to rhyolite. The isotopic compositions are variable for Carboniferous ...
-
(2006)Apatite preserves a record of the halogen and water fugacities that existed during the waning stages of crystallization of planetary magmas, when they became saturated in phosphates. We develop a thermodynamic formalism ...
-
(2006)The main elements and hydroxyl within garnets of eclogites from the west Tianshan were examined using electron microprobe at Fourier infrared spectroscopy. As a result, the garnets show zoning composition: that is spessartite ...
-
(2006)The major-ion (Mg2+, Ca2+, Na+, K+, multiscripts(SO, 4, mml:none(), mml:none(), 2 -), and Cl-) chemistry of Cretaceous seawater was determined from analyses of seawater-derived brines preserved as fluid inclusions in marine ...
-
(2006)Sawuer region is located in west Junggar, Jimunai County of Altay district and Hefeng county of Tacheng district, Xinjiang. The region is along the north margin of Kazakstan-Junggar plate. The intrusions (mainly acid) are ...
-
(2006)Many soils in southern Switzerland have a black color, contain a large amount of soil organic matter (SOM) and seem to have some andic properties although they did not develop on volcanic parent material. We investigated ...
-
(2006)This paper reports common Pb isotope data of omphacite in eclogite and feldspar in gneiss from the Chinese Continental Scientific Drilling (CCSD) (100 ~ 2000m). The radiogenic Pb of samples from the upper section (0 ~ 800m) ...
-
(2006)Carboniferous adakite-high-Mg andesite-Nb-enriched arc basalt and basaltic andesite (NEB) suites occur in the Northern Tianshan area (Xinjiang), many are associated with copper (gold) deposits (e. g., Dabate, Axi, Tuwu-Yandong, ...
