-
(2004)Early Mesozoic geological events played an important role in the structural evolution of Eastern and Central Asia. They involved collision between Siberia and Sino-Korean continents. This was accompanied by the closure of ...
-
(2000)The evaluated area and volume of ice sheets on the Earth during the Last Glacial Maximum (18-20 thousand years ago, oxygen isotope stage 2) are adjusted to the most recent data and our subglobal to global paleoglaciological ...
-
(2003)Investigated is a series of granitoid massifs in the composition of Yankansky, Tukuringrskii, Jagdinsky, Seledjino-Kerbinsky, Tokursky terrenes. The results of U-Pb-geochronologic, geochemical and Sm-Nd-isotope-geochemical ...
-
(2003)One of the key aims of geochronology, and the subject of the papers in this Special Publication, is the linkage of isotopic ages to petrological and textural information. A close link between the two types of information ...
-
GEODETIC EFFECTS OF THE OCEAN RESPONSE TO ATMOSPHERIC FORCING IN AN OCEAN GENERAL CIRCULATION MODEL (2004)We have adapted the Coupled Large-scale Ice-Ocean (CLIO) model in order to include atmospheric pressure forcing in addition to the classical atmospheric forcing ( heat and freshwater fluxes and wind stress). We have compared ...
-
(2002)Fluid fluxes within subsurface reservoirs give rise to surface displacements, particularly over periods of a year or more. Observations of such deformation provide a powerful tool for mapping fluid migration within the ...
-
(1996)Geodetic measurements have been conducted since the early 1970s to monitor surface deformation for seismic hazard assessment in Kamchatka. This paper is concerned with length measurements carried out at a geodetic network ...
-
(2003)A 'gravity anomaly' is essentially the difference between the gravitational acceleration caused by the Earth's masses and that generated by some reference mass distribution. However, there are numerous subtleties to the ...
-
(1990)Seismic tomography suggests the existence of broad variations of seismic velocity in the mantle. Regions with moderate velocities occupy a much smaller area than regions with anomalously low or high values. It follows that ...
-
(2002)Dismembered ophiolites occur in the Dinaride Ophiolite Zone (DOZ) that is related to the open-ocean Tethyan realm, whereas highly dismembered ophiolites occur in the Vardar Zone (VZ) related to a back-arc basin. The ...
-
(1987)A discussion is presented of geodynamic effects produced by distant earthquakes, as exemplified by the active Karachaganak gas-condensate field, located in a seismically inactive zone in northwestern Kazakhstan. The upper, ...
-
(2001)This paper deals with the geodynamic evolution and some problems of metallogeny of the Central Asian and Mongol-Okhotsk fold belts. It has been established that throughout its history (from Proterozoic to Cenozoic) all ...
-
GEODYNAMIC EVOLUTION OF THE EUROPEAN VARISCAN FOLD BELT: PALAEOMAGNETIC AND GEOLOGICAL CONSTRAINTS (1997)The Variscan fold belt of Europe resulted from the collision of Africa, Baltica, Laurentia and the intervening microplates in early Paleozoic times. Over the past few years, many geological, palaeobiogeographic and ...
-
(1998)Deep geodynamic (tectonic and magmatic) activity disturbs matter and temperature balance established previously in the Earth's crust; this results in metamorphism of the rocks. Five types of metamorphism can be recognized: ...
-
(2004)The similarity of the Early Proterozoic Udokan sedimentary basin to complexes of passive continental margins was established during analysis of the geodynamic environments of the southern framework of the Siberian Craton. ...
-
(2004)Systematic differences are observed in the petrology and major element geochemistry of natural peridotite samples from the sea floor near oceanic ridges and subduction zones, the mantle section of ophiolites, massif ...
-
(2001)It is proposed that there are three types of gold deposits in Eastern and Central Transbaikalia (Trans-Baikal province), namely: (i) high-sulphide intrusion-related deposits with some signs of porphyry deposits, (ii) ...
-
GEODYNAMICAL IMPLICATIONS FROM THE CORRELATION OF SURFACE GEOLOGY AND SEISMIC TOMOGRAPHIC STRUCTURE (1995)We have investigated the relationship between the lateral seismic structure in the mantle and the geological features associated with major mantle upwellings, the oceanic ridge system and hotspots. Using the technique of ...
