-
(1996)The article summarizes some of the author's conclusions and results obtained during experimental and mathematical studies of granitization. The following main points are discussed: the possibility that granitization may ...
-
(2001)This article presents the results of a study of the velocity characteristics and deep structure of the upper lithosphere in Precambrian shields, based on data from regional seismic investigations. An opinion on incompatibility ...
-
(1988)Any fluctuations in the ground water table which disrupt the capillary equilibrium of the moisture result in desorption of radon from the capillary surfaces. This fact is extremely important both for explaining the nature ...
-
(1988)Based on previous calculations by the authors, they conclude that of all of the containing compounds, the main source of diamond in the upper mantle (the zone were diamonds are thermodynamically stable) is methane. Since ...
-
(2006)The analysis of the flood hazard related to the areas downstream of landslide dams is one of the most interesting aspects of studying the formation and the failure of natural dams. The BREACH code [14], simulating the ...
-
(1990)In the treeless mountains of the Baikal rift zone (U.S.S.R.), which is a very cold environment, cryogenic weathering of gold-quartz veins takes place resulting in the formation of mechanical, aqueous and biogeochemical Au ...
-
(2002)Microseism time-series are non-stationary, non-linear and stochastic, and these characteristics can be reproduced by a forced non-linear damped oscillator. In the present study we show that such an oscillator is also able ...
-
(2004)Viscoelastic inversion is developed for a realistic, simple, causal hereditary model with a power-law attenuation. In this class of models the energy travels with a delay behind the wave front because the effective speed ...
-
(2002)Standard engineering weathering classifications, most of which are based on weathered granite, typically describe the appearance and condition of the weathered material (e.g. whether or not it is friable), the condition ...
-
(2006)The energetic aspects of redistribution of chemical bonds of lithospheric material during metamorphism, metasomatism, and hydrothermal activity attract interest in connection with the behavior of chemical elements ...
-
(1988)The association of many epithermal ore deposits with focal and dome volcanic structures, as well as the control of mineralization by major fault zones with no relationship to the volcanic structure, are expressed fairly ...
-
(2003)Nowadays, it is universally accepted that the majority of carbonate sediments accumulate under the direct or indirect influence of biota. The carbonate material is deposited in a purely biogenic way in the form of skeletal ...
-
(2002)The microstructures of two contrasting garnet grains are mapped using automated electron backscatter diffraction. In both cases there is a very strong crystallographic preferred orientation, with measurements clustered ...
-
(1993)The Chernobyl nuclear accident took place on 1986-04-26, and resulted in radionuclide pollution of vast regions of Byelorussia. This has raised several geochemical problems: (1) investigation of the distribution and behaviour ...
-
(2004)Ichnology straddles the boundary between palaeontology and sedimentology, and is becoming an increasingly important tool in both fields. For the palaeontologist, trace fossils allow insight into behaviour and biomechanics ...
-
(1992)Hutton's procrastination on the subject of unconformities left his cyclic vision of geology in the shadows, while his success in demonstrating the igneous origin of granite led on to Classical Magmatism, a paradigm of ...
-
(2000)The study of Upper Quaternary sedimentary sequences in the Pechora Sea by means of vibrocoring revealed three sediment units. The (youngest) sandy unit accumulated in marine environments later than 5000 years B.P. The ...

-
(2006)Supercontinents containing most of the earth's continental crust are considered to have existed at least twice in Proterozoic time. The younger one, Rodinia, formed at ~1.0 Ga by accretion and collision of fragments produced ...
-
(2002)Porphyry copper-gold, skarn copper-gold, sediment-hosted (Carlin-style) gold, breccia pipe, low-sulphidation epithermal gold, pluton-related (mesothermal or orogenic) gold vein and volcanogenic massive sulphide deposits ...
