(2001)An example of apparent polytypism in micas, i.e. twinning ofa polytype giving a diffraction pattern which simulates that of a different polytype with longer periodicity, is reported from the Ruiz Peak ferric phlogopite, ...
-
(2004)Small-scale shear zones inclined at intermediate angles to an earlier anisotropy are often observed in deformed rocks. They are traditionally described as shear-bands, C-bands, extensional crenulation cleavage or normal ...
-
(1996)Apparent stresses of 105 moderate-sized (magnitude m9 from 4.5 to 6.0) shallow earthquakes from the subduction zone near Kamchatka Peninsula (NW Pa-cific) were analyzed. Our results allowed us to formulate the following ...
-
(2002)A sound understanding of solute transport under stormflow conditions is crucial for assessing groundwater and stream water contamination risk. The vadoze zone exhibits its maximum protective effect, when solute transport ...
-
(2004)This paper describes the use of a backprojection algorithm to reconstruct subsurface images of the electrical resistivity in horizontal planes parallel to the surface. The algorithm can be applied to detect buried objects ...
-
(1989)In the Vochelamba test area (Kola Peninsula) the author has found unusual small tongue-shaped folds in Archaean leucocratic plagiogneisses. The folds were carefully removed from the rock, making it possible to examine them ...
-
(2001)The aim of this paper is to study the impact of boreal spruce forest on heat and water exchange between the land surface and the atmosphere by means of an advanced land surface model SWAP, which adequately treats the energy ...
-
(1989)A new preparative pyrolysis technique enabling the recovery and fractionation (into saturated hydrocarbons, unsaturated hydrocarbons, and aromatic hydrocarbons) of the total C6+ hydrocarbon fraction (instead of the C13+ ...
-
(2001)We developed an algorithm especially adapted to single-station wavelet detection of geomagnetic events, which precede or accompany the earthquakes. The detection problem in this situation is complicated by a great variability ...
-
(1996)We are using atomic-force microscopy (AFM), to address the interactions of a Pseudomonas sp. aerobic soil microbe with Fe(III)-(hydr)oxides. Research results to date show that AFM is a viable technique for in-situ and ...
-
(2003)The nearest neighbour method of strain analysis is re-evaluated and a method for objectively determining nearest neighbours, namely the Delaunay triangulation, is applied. A simulation study and application to a real set ...
-
(2004)We successfully applied deterministic deconvolution to real ground-penetrating radar (GPR) data by using the source wavelet that was generated in and transmitted through air as the operator. The GPR data were collected ...
-
(2001)Diamondoid distributions in solvent extracts from marine siliciclastic shales, marine carbonates, and coals of a wide variety of maturities were determined by GC-MSD. For this sample set, published diamondoid maturity ...
-
(2001)Sodic, calcic and subcalcic amphiboles are expressed by the combination of tremolite, edenite, tschermakite, glaucophane, magesioriebeckite and Fe-tremolite. Because such complex compositions of amphiboles provide enough ...
-
(2006)Electrical resistivity imaging is a widely used tool in near surface geophysical surveys for investigation of various geological, environmental and engineering problems including landslide. In this study, an electrical ...
-
(2004)Until recently, the concept of atomization energy was mainly applied to the explanation of physical properties of minerals. The introduction of the term specific atomization energy offered wide possibilities for determining ...
-
APPLICATION OF FAST WAVELET TRANSFORM FOR THE SOLUTION OF DIRECT PROBLEM OF GRAVIMETRIC PROSPECTING (2004)The approximation of real distribution of physical inhomogeneities in a geological medium by a number of bodies of correct geometrical form is a necessary stage in the analytical solution of the direct problem of gravimetric ...
-
(2003)Over 100 high-precision Fe isotope analyses of rocks and minerals are now available, which constrain the range in δ⁵⁶Fe values (per mil deviations in 56Fe/54Fe ratios) in nature from −2.50‰ to +1.5‰. Re-assessment of the ...
-
(2003)Fault geometry is a primary control on hanging wall deformation. In order to examine their geometrical relationships, a positive inversion analogue experiment was conducted using a rigid fault surface of listric geometry. ...
-
(2003)Fault geometry is a primary control on hanging wall deformation. In this study, a series of positive inversion analogue experiments was conducted using rigid fault surfaces of true 3D geometry, with consistent listric ...
