-
(2006)A new paleomagnetic study has been carried out on Mesoproterozoic sediments in the Jixian area, North China. Detailed stepwise thermal demagnetization allows us to isolate three components from 141 oriented drill-core ...
-
(2006)The nature of the crust in the Laxmi Basin, western margin of India is an uncertain issue; more importantly this has implications on paleo-geographic reconstructions of the western Indian Ocean. We have analysed three ...
-
(2006)The dinoflagellate cyst, palynofacies and foraminiferal records from the Early Eocene Figols Group of the Spanish Pyrenees exhibit major changes associated with relative sea-level fluctuations and variations in efficiency ...
-
(2006)To understand the impacts of long-term climatic episodes and sea-level changes on mid-oceanic atoll sedimentation, the stratigraphic changes of litho- and bio-facies, and stratigraphic levels of freshwater diagenetic ...
-
(2006)The coordination chemistry of molybdenum was investigated in nine series of synthetic silicate glasses, including sodium disilicate (NS2), sodium trisilicate (NS3), albite (Ab), anorthite (An), Ab50An50, Ab30An70, diopside ...
-
(2006)This study examined the effect Of CO2 on NaCl solubility in hydrothermal fluid, with the synthetic fluid inclusion technique. Fluid inclusions of 30-40 wt% NaCl and 5 mol % CO2 were synthesized, and their halite dissolution ...
-
(2006)The Grove Mountains of East Antarctica are an inland continuation of the Pan-African Prydz Belt. The area is made up of high-grade metamorphic complex and numerous intrusive granitoid bodies including foliated charnockite, ...
-
(2006)We have characterized ferroaxinite (up to 95 mol.% of end-member composition) from a contaminated granitic pegmatite cutting the magnetite-rich portion of an Fe-skarn body near Malešov, Czech Republic, by means of ...
-
(2006)Syn- and post-orogenic Cu mineralization in the northern Xinjiang Paleozoic accretionary and collisional orogenic belt in northwestern China is of great economic interest. About 40 Cu-bearing deposits have been discovered ...
-
(2006)Determining the age of glacigenic sediments is difficult for many geochronological methods because of the lack of suitable materials for analysis. Luminescence dating can be applied to the mineral grains making up the ...
-
(2006)Carbon, oxygen and strontium isotope ratios were determined in the uppermost Neoproterozoic carbonate rocks at Pastores (SW Salamanca, Central Iberia). The low δ18O V-SMOW values (15-19‰) indicate an alteration of the whole ...
-
(2006)The commonly held notion among earth scientists that Neoproterozoic low latitude glaciation (ca. 720-585 Ma), sometimes referred to as snowball Earth, caused major extinctions and imparted important evolutionary consequences ...
-
(2006)Origin and tectonic setting of the late Neoproterozoic Dokhan Volcanics (ca. 610–560 Ma by whole rock Rb–Sr and ca. 600–590 Ma by SHRIMP U–Pb zircon) in the Egyptian Eastern Desert is debated. Debate concerns the tectonic ...
-
(2006)We performed Nb K-edge XAFS spectroscopy experiments on a series of model compounds, natural glasses and anhydrous and fluid-bearing (H2O, F) synthetic glasses doped with 0.1 to 5 wt.% Nb2O5. In addition, we decribe a new ...
-
(2006)Earth accreted 4567 Myr ago from largely homogeneous material. From this initial capital of matter, differentiation formed the chemical and physical compartments of core, mantle, continents, ocean and atmosphere, that ...
-
(2006)A continuously operated gas monitoring station was emplaced within the epicentral area of the NW Bohemian swarm earthquakes overlying directly the active Mariánské Lázně fault. The recordings of 8-month continuous monitoring ...
-
(2006)Lattice-preferred orientations (LPO) of olivine, diopside, enstatite and garnet from the Zhimafang garnet peridotite body in the Sulu ultrahigh-pressure (UHP) metamorphic terrane (China) were measured using the electron ...
-
(2006)Mapping at 1:10000 scale of both north (N) and south (S) flanks of the Variscan Monesterio antiform in the Ossa-Morena Zone (southern Spain), in association with detailed petrographic and major element analyses of magmatic ...
-
(2006)The aim of this work is to investigate the influence of pH and the metal:humic substances (HS) ratio on HS complexing capacity and the stability and solubility of metal–HS complexes in solution. We selected four HS with ...
-
(2006)The Arenig ostracod fauna of Baltoscandia is the oldest known and amongst the most thoroughly studied ostracod faunas in the world. The fauna is dominated by eridostracans and palaeocopes, and comprises altogether about ...
