(2004)The reconstruction of the Late Weichselian glacial limits is based on geomorphological evidence combined with geological data. The maximum extension of the Last Glaciation has been established in Southeastern Lithuania. ...
-
(2001)Recent work with broadband sensors has demonstrated that useful data can be obtained from seismic sensors deployed on the deep seafloor for periods as long as 300 sec, but ocean-bottom seismometer (OBS) systems using ...
-
(1994)Four sections from the mid-Atdabanian to lowest Toyonian (middle Cambrian) along the Lena River of Siberia were sampled for carbon isotope stratigraphy. These show a mainly heavy but highly oscillatory δ13C signature for ...
-
(2001)A new computational method for the calculation of shallow water flows with moving physical boundaries is presented. The procedure can cope with shallow water problems having arbitrarily complex geometries and moving boundary ...
-
(2003)A Cenozoic multi-species record of benthic foraminiferal calcite Sr/Ca has been produced and is corrected for inter-specific offsets (typically less than 0.3 mmol/mol) and for the linear relationship between decreasing ...
-
(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 ...
