(2001)Direct measuremens of orthoclase (001) were performed using in situ atomic force microscopy (AFM) and synchrotron X-ray reflectivity to reveal the Α-scale dissolution process as a function of pH and temperature. Distinct ...
-
(1997)He and Ne isotope data from 48 mantle-rich well gases (3He/4He>0.1Ra) in 6 different regions of crustal extension around the world are used to derive both the average mantle He/Ne elemental ratio beneath the extensional ...
-
(1999)Speciation determinations involve uncertainty in system definition and experimentation. Identification of appropriate metals and ligands from basic chemical principles, analytical window considerations, types of species ...
-
(1989)Empirical data indicate that many properties of ground water and gas systems are unstable, e.g., the water films sorbed on the rock matrix, the oil-gas ratio and viscosity of the liquid, intrapore turbulence, dilatancy ...
-
(2004)Resonant Ultrasound Spectroscopy (RUS) uses normal modes of elastic bodies to infer material properties such as elastic moduli and Q. In principle, the complete elastic tensor can be inferred from a single measurement. For ...
-
(2001)The problem of seepage from a stream into an adjacent unconfined aquifer of semi-infinite extent, underlain by an impermeable sloping bed was considered in this study as a problem of one-dimensional unsteady-state groundwater ...
-
(1990)We discuss the behavior of the aggregate characteristics (salinity, gas factor) of groundwater-gas systems in the Turkmen forecasting network in the period 1988 to 1989. The measurement sites of this network are located ...
-
(2003)During the Late Barremian and Early Aptian (about 120 million years ago) intense volcanic degassing and extremely rapid release of methane hydrates contained in marine sediments added high amounts of carbon to the ocean ...
-
(1989)The present paper discusses the response of the free gases filling the jointed space of the Khibiny nepheline-syenite pluton to an engineering explosion. This pluton is one of the youngest igneous structures of the Kola ...
-
(1999)The δ13C record of total organic carbon in the Lake Baikal core BDP-93-2 over the last glacial/interglacial transition shows remarkable correlation with atmospheric CO2 fluctuations and the negative isotopic shift of 3.5–4‰ ...
-
(2001)Late Carboniferous and Early Permian strata record the transition from a cold interval in Earth history, characterized by the repeated periods of glaciation and deglaciation of the southern pole, to a warm-climate interval. ...
-
(2002)The effect of the speed of a time-domain reflectometry (TDR) pulse through the core rod and the shield rod(s) of TDR probes on the dielectric constant and water content of a soil with heterogeneous water content distribution ...
-
(1993)The Earth's lithosphere deforms when subjected to vertical and horizontal tectonic forces because it is not perfectly rigid. The deformation has both elastic (flexural) and inelastic (brittle and ductile creep) components. ...
-
RESTRUCTURING OF POLYGALACTURONATE ON ALUMINA UPON HYDRATION-EFFECT ON PHOSPHATE SORPTION KINETICS (2006)Hydration of organic coatings in soils is expected to affect the sorption of oxyanions onto hydrous Fe and Al oxides. We hypothesized that the hydration of polygalacturonate (PGA) coatings on alumina (Al2O3) increases their ...
-
(1997)The results of paleomagnetic studies of moraine deposits are analyzed. The observation data imply that moraine beds display a considerable scatter of magnetization vectors regardless of the rock age. It is inferred that ...
-
(2001)This paper examines the results of comprehensive structural (structural-geometric analysis of plane elements and kinematic analysis of faults and associated shear fractures) and paleomagnetic data for Jurassic rocks of the ...
-
(2003)Prominent negative δ13C excursions characterize several past intervals of abrupt (<100 kyr) environmental change. These anomalies, best exemplified by the >2.5‰ drop across the Paleocene/Eocene thermal maximum (PETM) ca. ...
-
(2003)Evidence is presented for retrograde reaction of silicate minerals with saline brine inside fluid inclusions during post-entrapment cooling. Ferropyrosmalite [(Fe,Mn)8Si6O15(OH,CI)10, where Fe>>Mn] has previously been ...
