-
(1986)This contribution summarizes and brings up to date the recommendations made by the IUGS Subcommission on the Systematics of Igneous Rocks for the classification of volcanic rocks when modal analyses are lacking. The ...
-
(1997)This study quantifies metal adsorption onto cell wall surfaces of Bacillus subtilis by applying equilibrium thermodynamics to the specific chemical reactions that occur at the water-bacteria interface. We use acid/base ...
-
(2004)This paper describes a chemical model that calculates solute and solvent activities and solid-liquid equilibria in the H-Na-K-OH-Cl-HSO4-SO4-H2O system from dilute to high solution concentration within the 0° to 250°C ...
-
(1995)A chemical separation method of Hf from rocks is presented. A procedure involving three stages of ion-exchange columns and sulfuric acid as an eluant produces consistent Zr- and Ti-free Hf separations. The methods described ...
-
(2003)A new empirical method has been devised for classification of mantle-derived garnets in kimberlite. Simple chemical screens have been developed to distinguish between garnets from different parageneses, based on Mg, Fe, ...
-
(1995)Classical ion-exchange chromatography combined with high-performance ion chromatography has been used for the separation of Nd and Sm for isotopic analysis of geological samples by mass spectrometry. The procedure has ...
-
(2003)In an attempt to delineate the base of a landfill and map the geometries of the host sediments, we have recorded a high-resolution seismic profile. To obtain sufficient resolution in the heterogeneous landfill environment, ...
-
(1993)A comparative analysis has been carried out for maps of recent vertical crustal movements (RVCM) for the European territory of Russia published at various times. We present maps for differences of rates of RVCM (1963–1971, ...

-
(1999)In terms of their chemistry, most of the Early Miocene volcanic rocks of Sakhalin can be referred to a tholeiitic series and merely a small amount, to a calc-alkalic series. Early Miocene volcanic eruptions occurred mainly ...
-
(2005)Fibrous zeolites (FZ) are the only group of natural zeolites that have been well investigated under pressure. The high-pressure (HP) behaviour of several FZ has been studied by means of in situ HP-single-crystal/powder ...
-
(2000)In this study the chemical structure of algaenans isolated from the freshwater algae Tetraedron minimum, Pediastrum boryanum and Botryococcus braunii are compared with their fossil counterparts by means of RuO4 oxidation. ...
-
(2002)Opaque minerals in the Qingzhen (EH3) and MacAlpine Hills (MAC) 88136 (EL3) enstatite chondrites were studied and compared with other EH and EL chondrites. All opaque minerals usually occur in multi-sulfide-metal clasts ...
-
(1996)Linear potential theory was used for a comparative study of tsunami excitation efficiency by piston-type and traveling-wave bottom motion. Wave energy was determined as a function of the size of excitation area, basin ...
-
(2004)Two automatic ways of estimating the regularization parameter in underdetermined, minimum-structure-type solutions to non-linear inverse problems are compared: the generalized cross-validation and L-curve criteria. Both ...
-
(2003)Velocity and water transport through the Windward Passage is estimated from a review of prior investigations and a new analysis of mooring observations conducted on February, 18, 1965 and November, 19-23, 1970 in the former ...
-
(1999)Short-period regional P/S amplitude ratios hold much promise for dis-criminating low-magnitude explosions from earthquakes in a Comprehensive Test Ban Treaty (CTBT) monitoring context. However, propagation path effects ...
-
(1996)Long-term resistance to displacement along frozen surfaces is an important characteristic of the strength of frozen ground. A knowledge of the value of this characteristic is necessary when calculating the load-carrying ...
-
(2004)The article presents experimentally determined physical and mechanical properties and elastic anisotropy of three core samples of metamorphic rocks (gneisses), which were drilled out and lifted from depths of 6849 – 8411 ...
