(2004)Thermo-mechanical physical modelling of continental subduction is performed to investigate the exhumation of deeply subducted continental crust. The model consists of two lithospheric plates made of new temperature sensitive ...
-
(Oxford University Press, 2004)This book deals with continents, where more than 95% of the earth’s population lives. We discuss the present state of knowledge on the origin and evolution of continents. We pose a number of questions and attempt their ...
-
(1997)An understanding of the formation of new continental crust provides an important guide to locating the oldest terrestrial rocks and minerals. We evaluated the crustal thicknesses of the thinnest stable continental crust ...
-
(2003)To better understand the extended X-ray absorption fine structure (EXAFS) spectroscopic information obtained for complex materials such as those encountered in Earth materials, we propose to use the Continuous Cauchy Wavelet ...
-
(2005)Multianvil melting experiments in the system CaO–MgO–Al2O3–SiO2–CO2 (CMAS–CO2) at 3–8?GPa, 1340–1800°C, involving the garnet lherzolite phase assemblage in equilibrium with CO2-bearing melts, yield continuous gradations ...
-
(2004)A continuous record of the geomagnetic field direction during of cooling of the Monchegorsk (2.5Ga), Kivakka (2.45 Ga) and Bushveld (2.06 Ga) layered intrusions was conducted for the first time. The low-Ti titanomagnetites ...
-
(2002)Among the minerals of the selenide assemblage at the Niederschlema-Alberoda uranium deposit, Erzgebirge, Germany, members of the mercurian giraudite-hakite solid solution intergrown with berzelianite and galena have been ...
-
(1996)In spite of the major importance of monazite as a repository for the rare earths and Th in the continental crust, for U-Th-Pb geochronology, and as a possible form for high-level nuclear waste, very little work has been ...
-
(2003)Clinozoisite and topaz are examined to pressures of 36 and 24 GPa, respectively, at 300 K using infrared spectroscopy. Both minerals metastably persist throughout this pressure range at ambient temperature. Both stretching ...
-
(1997)Microthermometry and stable isotope data enable us to distinguish between two contrasting sets of fluids involved in the Hercynian and Alpine metamorphic events in the Western Carpathians. High-temperature smoky quartz ...
-
(2004)Distinct cyclicity in lithology and microfaunal distribution in sediment cores from the Mendeleev Ridge in the western Arctic Ocean (water depths ca. 1.5 km) reflects contrasting glacial/interglacial sedimentary patterns. ...
-
(2019)The paper presents new original data and a review of previous studies on the Late Carboniferous – Early Permian granitoids of the Kunush and Kalguty intrusive complexes from the Kalba fold belt (East Kazakhstan). These ...

(PANGAEA, 2016-05-19)
-
(2002)The Paleoproterozoic Svecofennian Orogen in the Fennoscandian shield can be regarded as one entity or as a collage of several accretionary units. To test for the possible occurrence of a suture zone dividing the Svecofennian ...
-
(1996)Trace element compositions of amphibole (+/-phlogopite) - bearing spinel lherzolite xenoliths have been investigated with regard to their oxidation state and tectonic setting to evaluate the processes associated with the ...
-
(2002)The induced magnetic signature at satellite altitude associated with crustal and mantle electrical heterogeneities is examined using five different Earth models. The three-dimensional induction problem is solved in these ...
-
CONTRIBUTION OF CARBONATE ACCUMULATION RATE TO DECLINE IN CONCENTRATION OF PHOSPHORUS IN LAKE SEVAN (1989)The eutrophication of Lake Sevan that has resulted from the drawdown of its level has destabilized the calcium carbonate systems, which in turn has affected the precipitation of calcium carbonate by disrupting the natural ...
-
(1997)To study whether tungsten isotopic ratios observed in terrestrial samples relative to W ratios in an iron meteorite could be made by neutron-capture reactions in the iron meteorite, the fluxes of thermal and epithermal ...
-
(1987)Numerous independent observations contradict the hitherto accepted notions as to the contribution that shear-induced metamorphism makes to the overall metamorphic process. The authors attempt to review this, based primarily ...
