(1998)Global sea-level fluctuated markedly during the early Silurian, probably as a result of the waxing and waning of ice-sheets in the South American portion of Gondwana. The highest sea-levels of the Silurian are recorded by ...
-
(1998)We present results of a study of the 53Mn-53Cr systematics in various solar system objects: angrites, eucrites, chondrites, diogenites, pallasites, the Earth and the Moon, and SNC meteorites. The primary goal of this study ...

Early stage of the Central Asian Orogenic Belt building: evidences from the southern Siberian craton (Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2017)
-
(1988)The predominant rocks of the Anabar shield are basic pyroxene-plagioclase schists, metaultramafics, and various gneisses and granites with a minor number of partings of amphibolite, quartz, marble, calciphyre and other ...
-
(2001)The main peculiarity of the tectonic and magmatic development of the Moon is its resemblance to the Paleoproterozoic stage of the Earth development. The Moon shows no analogues of both the ancient (Archean) terrestrial ...
-
(2000)We report detailed high precision combined single grain U-Pb and Lu-Hf studies of early zircons to obtain more reliable indications of the extent of mantle depletion and crustal recycling in the Archean. Despite the ...
-
(2002)Very different palaeogeographical reconstructions have been produced by a combination of palaeomagnetic and faunal data, which are re-evaluated on a global basis for the period from 500 to 400 Ma, and are presented with ...
-
(2004)Palaeomagnetic and faunal data have been re-evaluated on a global basis for the period from 400 Ma (early mid-Devonian) to 250 Ma (latest Permian). The boundaries of the major terranes are considered and defined. Six new ...
-
(1999)Earth system science has influenced and continues to influence our understanding of the relationship between humans and nature. The first important lessons were that our planet is not the center of the universe and we are ...
-
(1989)Vertical displacements of the solid surface of the earth resulting from lunar-solar high and low tides are asymmetrical relative to the zero position, in that the amplitudes of the high tides are greater than those of the ...
-
(2001)The Earth's main magnetic field, arising in the core, should, in the ocean, have a well-defined uniform gradient with depth. Superimposed upon this uniform gradient may be magnetic signals due to a variety of sources. These ...
-
(1998)The lowest magnitude of complete reporting and its variations in space and time are estimated for several regional earthquake catalogs. The discussion focuses on questions of methodology and the space-time inhomogeneity ...
-
(2003)Earthquakes are an important source of knowledge on mode of deformation and strength of rocks. According to the available hypocenter locations and recent relocations, most of seismicity in the Baikal rift is confined to ...
-
(1990)The system of stresses in the lithosphere (0–59 km) and upper asthenosphere (60–150 km) was analysed on the basis of focal-mechanism data for events of M > 5.0 in 1964–1982. The zoning was made considering types of faulting ...
-
(2003)Engineering seismology is the link between earth sciences and engineering. The main input of engineering seismology in engineering design are loading conditions which must satisfy certain conditions regarding their level ...
-
(1997)Earthquake prediction is an area of research of great scientific and public fascination. The reason for this is not only that earthquakes can cause extremely large numbers of fatalities in a short time, but also because ...
-
(2004)The recent scientific advances in understanding the hierarchical nature of the lithosphere and its dynamics based on systematic monitoring and evidence of its space-energy similarity at global, regional, and local scales ...
-
(1988)A new seismometer design based on the interaction of the sensor component of the instrument with the earth's magnetic field significantly broadens the range of frequencies recordable by a single instrument. This design ...
