(2006)In this study we test if calcite shells of the common mussel, Mytilus edulis, contain barium in proportion to the water in which they grew. Similar to all bivalves analyzed to date, the [Ba/Ca]shell profiles are characterized ...

BARIUM-RICH AUTHIGENIC CLINOPTILOLITE IN SEDIMENTS FROM THE JAPAN SEA-A SINK FOR DISSOLVED BARIUM? (1999)Exceptional barium-rich clinoptilolite, a heulandite-group zeolite, with Ba contents of up to 1.83 wt.% BaO occurs in Miocene sediments from the Yamato Basin of the Japan Sea (ODP Site 797). The clinoptilolites with highest ...
-
(2006)The basal plane reactivities of the sheet silicates apophyllite and phlogopite have been studied by hydrothermal atomic force microscopy (HAFM) in situ in aqueous solutions at temperatures from 20 to 140 °C. At pH 4-5.6 ...
-
(2005)The Siberian Traps represent one of the most voluminous continental flood basalt provinces on Earth. The mass extinction at the end of the Permian was the most severe in the history of life. In the present paper, these two ...
-
(2003)Mesozoic intraplate continental basaltic volcanism at the Franz Josef Land (FJL) archipelago is related to the activity of the Iceland plume [1, 2]. The volcanic activity was less significant but genetically close to the ...
-
(2001)This paper discusses the petrography, petrochemistry and geochemistry of basalts of the Erdagou volcanic-cherty Formation in the Taukha terrane, Southern Sikhote-Alin. The mid-Jurassic (Callovian) age of the basalts is ...
-
(2000)A mineralogical classification of sulfides containing base metals (BM) and platinum group elements (PGE) is proposed based on BM-PGE ratios. Group A comprises BM sulfides carrying PGE as trace or minor elements (e.g., ...

-
(2001)Infrared (IR) spectroscopy has a long and successful history as an analytical technique and is used extensively (McKelvy et al., 1996; Stuart, 1996). It is mainly a complementary method to X-ray diffraction (XRD) and other ...
-
(2001)The Mongol-Siberian belt of rejuvenated mountains is an ordered system of large domes, zones of linear warping, and the Baikal rift zone on the broad basement doming. Its morphology is paragenetically related to the shape ...
-
(2003)Partial melting of the mantle is polybaric which implies that the phase relations change during partial melting. In addition to the pressure the composition of the melt depends on the melting mode. Various melting models ...
-
(2001)The peneplaned Archean craton of the Fennoscandian Shield served as a platform upon which a continental margin assemblage, the Karelian Supergroup, was deposited between ~2.45 and ~1.9Ga. Major subaerial unconformities ...
-
(2001)The long-term (climatic) hydrologic response of a basin may be quantified using the evaporation efficiency (E/Ep or actual evaporation ratio with potential evaporation) and runoff ratio (R/P or ratio of runoff loss to ...
-
(2003)Three large batholiths formed in the Central Asian fold belt in the period 310-190 Ma: Angara-Vitim, Hangayn, and Henteyn-Daurian. They are made up of granitoids of variable composition - from tonalities and plagiogranites ...
-
(1988)The base of the Cordylodus proavus conodont Zone is the most appropriate horizon for the Cambrian–Ordovician Boundary. At Batyrbay the horizon reflects a significant global eustatic event that is marked by distinctive ...
-
(2003)When designing hydraulic structures, civil engineers have to evaluate design floods, i.e. events generally much rarer that the ones that have already been systematically recorded. To extrapolate towards extreme value events, ...
-
(2002)The purpose of this analytic-numerical Bayesian forecasting system (BFS) is to produce a short-term probabilistic river stage forecast based on a probabilistic quantitative precipitation forecast as an input and a deterministic ...
-
(1999)We present a source model for the beginning of earthquakes based on the Griffith's fracture criterion. The initial state is a critical state of pre-existing circular fault, which is on the verge of instability. After the ...
-
(1988)New information has recently been obtained from experimental research on gold and silver solubilities in magmatic melts and fluid systems. This paper considers whether gold and silver are lost from volcanic rocks, by means ...
