(1987)On a cryogenic investigation solid H2S was successively observed after freezing CO2 in water-poor fluid inclusions in halite of Cambrian Siberian salts. Melting of a H2S solid phase occurs at nearly eutectic temperatures ...
-
(2001)The high field strength elements (HFSE) play a critical role in the interpretation of chemical variation within subduction-related magmas by providing an assumed mantle-dominated 'baseline' from which enrichments in many ...
-
(1999)Standard partial molal thermodynamic parameters for the aqueous chlorinated-ethylene species, perchloroethylene (PCE), trichloroethylene (TCE), 1,1-dichloroethylene (1,1-DCE), cis-1,2-dichloroethylene (cis-1,2-DCE), ...
-
(2001)Extension of Ar-Ar methodology has been used to determine mineralisation ages from mica inclusions and to simultaneously evaluate the noble gas and halogen composition of inclusion fluids within irradiated quartz vein ...
-
(1989)The role of volatiles in island-arc magma generation is widely discussed in the geologic literature. Two of the most important volatile mineralizers are fluorine and chlorine, whose principal accumulator minerals in igneous ...
-
(2003)We describe the structure of a listric growth fault system from SE Asia, using high-resolution, 3-D seismic data. The fault system shows systematic changes in geometry and kinematics that are sympathetic with along-strike ...
-
(1996)The structure of haploandesitic magma was modeled via in situ, high-temperature Raman spectroscopy along the join K2Si4O9-K2(KAl)4O9 from 25 to 1236°C. These glasses and melts consist of Q^4, Q^3, and Q^2 structural units. ...
-
(2002)Powder infrared spectra of perovskites across the CaTiO3-SrTiO3 solid solution have been collected at room temperature for the range 20–700 cm−1. Frequency, intensity, and line broadening parameters vary with a pattern ...
-
(Федеральное государственное автономное образовательное учреждение высшего образования «Северный (Арктический) федеральный университет им. М.В. Ломоносова», 2018)The paper presents an analysis of the physico-chemical properties of hard-to-recover, high quality oils in the Russian sector of the Arctic. In view of the insufficient knowledge of the properties and conditions occurrence ...
-
(PANGAEA, 2010-04-12)Lower jaws (containing the teeth), eyes, and skin samples were collected from harp seals (Pagophilus groenlandicus) in the southeastern Barents Sea for the purpose of comparing age estimates obtained by 3 different methods, ...
-
(2004)The effect of H2O on harzburgite-saturated melts has been quantified with a series of hydrous and anhydrous melting experiments using a piston-cylinder device. Experimental conditions were 1.2–2.2 GPa and 1175–1500°C. Melt ...
-
(2004)A NS trending Cenozoic fold-and-thrust belt has developed in the western part of the Hidaka Collision Zone (HCZ), central Hokkaido, Japan. A quantitative estimation of the late Cenozoic convergence rate at the front of the ...
-
(2003)Dicynodont therapsids have long played an important role in global Late Permian and Triassic biostratigraphy, including recent studies of the effects of the extinction at the Permian-Triassic boundary on terrestrial ...
-
(2000)Design seismic forces depend on peak ground acceleration (PGA) values and on the shape of response spectra (RS) dictated by building codes or that need to be evaluated on a site-specific basis. The PGA values and RS strictly ...
-
(2005)Rare gases have been measured in ultramafic xenoliths from European volcanic provinces, Dreiser Weiher (Germany), Massif Central (France) and Kapfenstein (Austria), to characterize the rare gas signature of a proterozoïc ...
-
(PANGAEA, 2018-11-08)Two separate field excursions were carried out in 2017 to investigate subsea permafrost degradation offshore of the Bykovsky Peninsula in Siberia. In April, four ice cores were drilled offshore to measure sea ice thickness, ...
-
(2001)The heat capacities of 27 glasses have been determined from room temperature to temperatures corresponding to supercooled liquid behavior. The investigated compositions are based on a haplogranite (near the 2-kbar pH2O ...
-
(1999)Six members of the annite-siderophyllite join were synthesized in a three step process - crystallization of biotite from gels, decomposition of the fine-grained biotite under oxidizing conditions and resynthesis of Fe-Al ...
-
(2002)From heat capacities measured adiabatically at low temperatures, the standard entropies at 298.15 K of synthetic rutile (TiO2) and nepheline (NaAlSiO4) have been determined to be 50.0 ± 0.1 and 122.8 ± 0.3 J mol-1 K, ...
