-
(2003)Temporal characteristics of secular variations (SV) over the last hundred of years are studied using the wavelet transformation, providing estimates of dispersion and energy parameters of the process analyzed. The presence ...
-
(2005)Wavelet coherence analysis is defined and used to analyze the relationships between Length-Of-Day (LOD) variations and El Niño-Southern Oscillation (ENSO) on interannual scales. Using the newest observation data, this study ...
-
(2002)Magma mixing is a common process and yet the rates, kinematics and numbers of events are difficult to establish. One expression of mixing is the major, trace element, and isotopic zoning in crystals, which provides a ...
-
(2001)We have addressed the problem of subduction initiation with a solid-mechanical and fluid-dynamical approach, using a finite-element method. The setup has been extended by a rate-sensitive coupling at the bottom of a ...
-
(2003)Explicit equations for approximate linearized reflection-transmission coefficients at a generally oriented weak-contrast interface separating two generally and independently anisotropic media are presented. The equations ...
-
(2001)There are many observations in naturally deformed rocks on the effects of mineral reactions on deformation, but few experimental data. In order to study the effects of chemical disequilibrium on deformation we have ...
-
(2001)Weathering profiles developed on the top surface of a bentonite (containing Al-Mg montmorillonite) and a K-bentonite (containing mixed-layer illite-smectite (I-S)) under Central European temperate conditions were studied ...
-
(2002)This paper characterizes the weathering products of the two-mica Oporto granite in terms of its mineralogical, chemical, geotechnical and physical properties. This information is used to identify a physical property that ...
-
(2004)Weathering occurs over a wide range of scales. To link features through these scales is a major challenge for interdisciplinary weathering studies. Fractal approach seems to be specially useful for this purpose. We introduce ...
-
(2011)В статье обсуждаются различные построенные и только строящиеся информационные и технологические компоненты портала «Геология Дальнего Востока России» для хранения и интеграции различных типов данных и объединение этих ...
-
(2002)A method for the calculation of the factor of safety by using the limit equilibrium method and considering the dilatancy of discontinuities on which the wedge rests is addressed. The direction of shear force on each ...
-
(PANGAEA, 2010-04-04)Cryolithological, ground ice and fossil bioindicator (pollen, diatoms, plant macrofossils, rhizopods, insects, mammal bones) records from Bol'shoy Lyakhovsky Island permafrost sequences (73°20'N, 141°30'E) document the ...
-
(2004)During recent years there has been a re-assessment of the glacial history of the Russian Arctic, from the Kola Peninsula in the west to the Lena Delta and beyond in the east. In this context, work has been carried out on ...
-
(PANGAEA, 2001-10-28)A large section near the village of Hongurei on the Pechora River, ca. 100 km inland from the Barents Sea coast, reveals the following stratigraphic record of the last glaciation: The lowest units are lacustrine silt ...
-
(2001)Pumping tests in an outwash sand at the Camp Dodge Site give hydraulic conductivities (K) approximately seven times greater than conventional slug tests in the same wells. To determine if this difference is caused by skin ...
-
(1989)Unusual glass pebbles and fragments were found in northwestern Siberia several years ago and studied by us after our geologic and geomorphic survey of the localities. Our assumption that these glasses are tektites predetermined ...
-
(1996)The paper discusses the history of East Gondwana and its relationship with West Gondwana in the period preceding the collision, and with the Prototethys. The relationships between East and West Gondwana and the Prototethys ...
-
(PANGAEA, 2011-09-14)
-
(2001)Iterative comparison between experimental work and numerical simulations has been used to predict oil-recovery mechanisms in fractured chalk as a function of wettability. Selective and reproducible alteration of wettability ...
