(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 ...
-
(1996)Due to the large partition coefficients of garnet for Lu compared to Sm, Nd, and Hf, garnet residual from crustal melting events has a large potential for retaining Lu and, over time, producing high reservoirs in the lower ...
-
(2004)The concentrations of major and minor elements were determined in the surface water in different parts of the waste processing system (sludge pond, precipitation pits, and drainage streams) of the tailings dumps of a Pb-Zn ...
-
(2005)Polycyclic aromatic hydrocarbons (PAHs) with a hydrous or an unhydrous mineral matrix were impacted and analyzed, to study the behavior of PAHs against shock. Results of the shock experiments suggested that volatiles ...
-
(2001)Oceanic sediments (volcanoterrigenous mud and hemipelagic and eupelagic clay) were leached by IM NH2OH · HCl + 25% CH3COOH at different solid/liquid ratios (from 1/800 to 1/20) to study the REE behavior in the leachates. ...
-
(1989)The behavior of scandium during lateritization of any given rock is based on how it is distributed among the main (rock-forming) and weathering-resistant accessory minerals of the rock. Scandium most likely is leached ...
-
(2004)The behavior of isotopic systems (Sm-Nd, Rb-Sr, K-Ar, and U-Pb) in minerals from Archean plagiogneisses in the outer-contact zone of an alkaline-ultramafic intrusion points to an age discordance that resulted from the ...
