-
(2001)A new method to estimate strain and competence contrast from natural fold shapes is developed and verified by analogue and numerical experiments. Strain is estimated relative to the nucleation amplitude, AN, which is the ...
-
(2003)Infrared powder-absorption spectra of nine natural and five synthetic olivine samples across the forsterite-fayalite join have been investigated at room temperature in the range 70-1400 cm-1. Variations of peak positions ...
-
(1999)Strain properties of rocks were classified as a function of lithology, origin, porosity, water content, and permafrost in the Baikal region. Velocities of elastic waves were found to overlap for rocks of different origins ...
-
(2003)A new technique to determine flattening strain from initially concentric folds is described in this paper. The proposed method is simple and involves direct measurements on fold profiles. It requires measurement of the ...
-
(2003)To test the accuracy and reliability of the strain gauge technique for calcite e-twin analysis, calcite e-twin strain and finite strain were determined using a new tectonic marker, inoceramid shells (macrofossils composed ...
-
STRAIN ESTIMATION FROM FLATTENED PARALLEL FOLDS: APPLICATION OF THE WELLMAN METHOD AND MOHR CIRCLE (2006)Parallel folds exhibit a characteristic orthogonal relationship between the tangent and the corresponding isogon drawn at any point on folded surface. Modification of parallel fold to flattened parallel fold by superimposition ...
-
(2004)In order to describe and explain the effect of bowing of marble facade panels, neutron time-of-flight diffraction was applied to determine residual macro- and microstrain on the calcite mineral phase. The measurements were ...
-
(2004)We use forward models based on recent high-pressure experimental data on mantle minerals to predict the seismic anisotropy produced by plastic strain of orthorhombic wadsleyite, the dominant mineral in the upper transition ...
-
(2001)The shape preferred orientation (SPO) of porphyroclasts was determined in high temperature mylonites. The porphyroclasts approach rhomboidal (sillimanite) or elliptical (garnet, plagioclase, sillimanite) shapes, and exhibit ...
-
(2002)Magma mixing structures from three different lava flows (Salina, Vulcano and Lesbos) are studied in order to assess the possible chaotic origin of magma mixing processes. Structures are analysed using a new technique based ...
-
(1990)The prediction problem of a stochastic point process in terms of loss function γ is considered. Losses depend on prediction errors: , the fraction of failures-to-predict; and τ̊, the fraction of alarm time. The structure ...
-
(2004)On the basis of the use of broadband (25–150 s) Rayleigh wave group speeds to estimate the 2ψ component of azimuthal anisotropy, we present evidence for a stratification of anisotropy in the uppermost mantle at large scales ...
-
(2001)Scaling models of geofields attempt to capture the strong and wide-range variability ubiquitous in geosystems. Unfortunately, they are generally both isotropic (self-similar) and monofractal (non-intermittent, quasi-Gaussian). ...
-
(2001)In Paper I, we showed how anisotropic scaling spectral (second-order) models of the magnetization (M) were realistic at both high- and intermediate-wavenumber regimes of the surface magnetic field (B). However, in order ...
-
(2001)Foraminiferal assemblages from the Belaya Glina basin, which extended from the Black Sea to the Aral-Turgai region and eastern Central Asia, and from the inner seas of Transcaucasia are analyzed. The assemblages mainly ...
-
(2003)Stratigraphic and geographic distribution of corals of the family Agetolitidae Kim is analyzed. The family is a unique group bearing characters of both tabulatomorphic and rugose corals.
-
(2000)Seismic reflection profiles from the Lake Baikal Rift reveal extensive details about the sediment thickness, structural geometry and history of extensional deformation and syn-rift sedimentation in this classic continental ...
-
(1996)Vendian to Cambrian age sedimentary rocks of the northern Siberian craton record Early Cambrian rifting from ˜ 543 to 530 Ma and the onset of regional thermal subsidence in early Tommotian time. A similar tectonic history ...
-
(2004)First data on the Late Cretaceous floras occurring in association with diverse invertebrate and vertebrate faunas at 11 localities of southern Mongolia are reported. Ages and stratigraphic position of studied plant remains ...
-
(1996)A new stratigraphic scheme of the Quaternary deposits of Belarus is discussed. The scheme is based on the principle of succession in evolution of the fossil biota during the interglacial Pleistocene epochs. Stages in the ...
