-
(2002)Experimental results of a study of electromagnetic fields due to detonation of high explosive charges with mass of a few kilograms are presented in this paper. Data show that in the initial stage of explosion the fields ...
-
(2003)The mineral, triclinic astrophyllite, was investigated using the Mossbauer effect. The Mossbauer spectra of triclinic astrophyllite at 298 K, 180 K and 90 K were measured, and the quadrupole splitting distributions (QSDs) ...
-
(2001)Traditional ichnofabric-descriptive (semiquantitative:l schemes rely upon subjective estimates of the degree to which original sedimentary fabrics have been disrupted. This paper presents an objective method of quantifying ...
-
(2001)The total organic carbon (TOC) of many recultivated mine soils is composed of a fraction that is lignite-derived as well as a fraction that is derived from recent plant litter. In these soils, precise quantification of the ...
-
(2002)Determination of Fe3+/ΣFe in minerals at submicrometre scale has been a long-standing objective in analytical mineralogy. Detailed analysis of energy-loss near-edge structures (ELNES) of the Fe L23 core-loss edges recorded ...
-
(2004)The paramagnetic clay mineral illite can have important controls on fluid permeability and microporosity in sedimentary rocks. Increases in illite content of a few percent can reduce permeability by several orders of ...
-
(2003)In this paper isotope ratio mass spectrometry is used to determine the methane (CH4) oxidation fraction in the rhizosphere of intact rice plant-soil systems. Earlier studies on quantification of the methane oxidation were ...
-
(2003)A quantitative physical model is presented which includes the factors that control the presence, or absence, of internally derived excess 40Ar or excess 4He in geological systems. In particular, the model incorporates the ...
-
(2003)This paper deals with the errors introduced in the construction of cross-sections due to the use of apparent dips and thicknesses when projecting data onto the plane of section. These errors are analyzed under the perspective ...
-
(2002)Measurements of CO2 fluxes from ground surface of the atmosphere (soil respiration) are needed to quantify biotic and abiotic reaction rates in unsaturated zones and to gain insight into the importance of these processes ...
-
(2001)A computationally efficient method to direct and evaluate the sufficiency of site characterization data is demonstrated on two synthetic subsurface geometries. This method, entitled reliability-based exploration (RBE), ...
-
(2002)The Box-Cox transformation is widely used to transform hydrological data to make it approximately Gaussian. Bayesian evaluation of parameter uncertainty in stochastic models using the Box-Cox transformation is hindered by ...
-
(2004)Apatite, titanite and olivine samples were bombarded with a ~150 MeV proton beam to produce ~108 atoms/mg of spallation 3He. High-precision stepped-heating experiments were then performed in which the artificial 3He and, ...
-
(2002)The effect that recent relief changes may have on the distribution of rock ages with elevation is investigated for a range of thermochronometers. From the solution of the heat transport equation in a crustal block undergoing ...
-
(2000)This paper reviews the investigations that quantify metal-bacteria, organic-bacteria, and bacteria-mineral adsorption reactions. The studies are divided into the two main approaches used to quantify adsorption: bulk ...
-
(1999)A method for analyzing low abundances of the platinum group elements (PGEs) and gold has been developed using cation exchange chromatography and ultrasonic nebulization inductively coupled plasma mass spectrometry (USN-ICP-MS). ...
-
(2001)A series of five Cenozoic atmospheric general circulation model (AGCM) experiments has been performed using a new set of paleogeographic reconstructions for 55, 40, 33, 20 and 14 Ma. The five continental reconstructions ...
-
QUANTIFYING THREE-DIMENSIONAL SILICATE FABRICS IN CUMULATES USING CUMULATIVE DISTRIBUTION FUNCTIONS (2004)We present a new method for quantifying three-dimensional silicate fabrics and the associated uncertainties from grain orientation data on three orthogonal sections. Our technique is applied to the orientation of ...
-
(2003)A critical aspect of the debate about the origin and conditions of metamorphism of the Alpe Arami (AA) peridotite is the disagreement over how much ilmenite is contained in the older generation of olivine and therefore how ...
