-
(2006)In the northern Baltic Shield, diorites, monzodiorites, and quartz diorites are constituents of postorogenic granite massifs, the localization of which was controlled by NE- and NW-trending fault zones. The NE-trending ...
-
(2006)In the coastal (shallow-water) part of Lake Baikal, we studied gas from several ice holes, which represent polynyas (ice-free water areas) typically formed at the end of March–beginning of April due to intense gas release ...
-
(2006)Friable sediments of different glacial and interglacial epochs are abundant in the White Sea and adjacent land areas influenced by Pleistocene glaciations. Numerous studies carried out in neighboring areas of the Kola and ...
-
(2006)The transformations (density, composition, or shape alterations) of fluid inclusions under isobaric cooling and isothermal compression have been experimentally modeled. The H2O-CO2 -CH4 inclusions used in the model experiments ...
-
(2006)In the 1990s, peculiar Late Mesozoic structures of intracontinental extension, the so-called metamorphic core complexes (MCC), previously considered inliers of the Early Precambrian basement, were defined in the Transbaikal ...
-
(2006)It is known that high-order spectra (second order) and coherences (greater than two) are used to detect phase-correlated oscillations in stationary time series. High-order coherences (HOCs) serve as a measure of phase ...
-
(2006)The fineness of gold from endogenic gold deposits varies from 500 to 999. The causes of this wide variation have been discussed by many researchers and were comprehensively considered by Petrovskaya. Differences in depth ...
-
(2006)Principal trends in the development of mathematical geophysics at the modern stage include the comprehensive development of the approximation approach. Researchers widely use approximations of external elements of gravitational ...
-
GENERATION AND PROPAGATION OF CATASTROPHIC TSUNAMIS IN THE SEA OF OKHOTSK BASIN: POSSIBLE SCENARIOS (2006)Because of the probability of the occurrence of a strong earthquake in the central part of the Kuril–Kamchatka Arc, which corresponds to the seismic gap (SG) region, it is necessary to take into account the possibility of ...
-
(2006)The monazite group minerals (LREE, Ca, Th)[PO4] are the most important LREE-carriers in the rocks of the Earth. Monazite-(Ce) is considered the most abundant REE-bearing mineral. The monazite group includes anhydrous ...
-
(2006)Reconstruction of the parameters of stress tensor based on focal mechanisms of earthquakes occurring before the Sumatra–Andaman earthquake (SAE) showed that deviatory stresses and all-round compression in the western Sunda ...
-
(2006)The anomalous position of Eu in chondrite-normalized REE patterns of minerals has attracted the attention of geochemists for several decades. The works by J.A. Philpotts (1966–1973) on behavior of Eu and other REEs in ...
-
(2006)We have already carried out analysis of the unified scaling law for earthquakes (hereafter, USLE) both for global and several regional earthquake catalogues. In this paper, we present results of an analysis and mapping of ...
-
(2006)Variations in the composition and mineral assemblages of boronaluminosilciates (serendibite, grandidierite, kornerupine, and tourmaline) were studied in the abyssal and hypabyssal skarns of New York and California, United ...
-
(2006)Gem-quality chrysolite (peridot) from a phlogopite deposit related to the Kovdor ultrabasic-alkaline massif in the Kola Peninsula, Russia, was studied using a variety of techniques (optical mineralogical microscopy, chemical, ...
-
(2006)Micrometer-sized inclusions in dark gray diamond crystals of octahedral habit from Yakutian kimberlites were studied by analytical scanning electron microscopy and analytical transmission electron microscopy. In addition ...
-
(2006)To obtain reliable age data on the Ni-bearing intrusions of Kamchatka and to support their correlation with similar complexes of northeastern China, we dated them with 40Ar/39Ar and U–Pb methods. For this purpose we selected ...
-
(2006)Experiments simulating impact melting and vaporization were performed to study variations in the valence state of P on the Moon. It was shown that P changes its valence and is partially transformed from oxidized (phosphate) ...
-
(2006)Polylithionite is a characteristic lithium mica of alkaline pegmatites, metasomatized peralkaline granites, and zones of alkaline metasomatism. Among lithium-bearing micas, polylithionite shows the highest lithium oxide ...
-
(2006)The South Anyui Suture (SAS) resulted from the closure of a past oceanic basin and subsequent collision between the North American and North Asian continents. Many geological aspects of this essential tectonic element of ...
