(2002)The Valley of Lakes, Mongolia, is a key region in which to elaborate the geochronology of biostratigraphic horizons of the continental Paleogene and Neogene. Here, basaltic volcanism is developed widely. Basalt flow units ...
-
(2004)The epiplatform (Upper Cretaceous-Paleogene) and neotectonic (Neogene-Quaternary) evolutionary stages and morphostructures are distinguished in Mongolia. The neotectonic structures are characteristic of the orogenic zone ...
-
(1998)Monazite grains are generally concordant and, with an electron microprobe, give Th-U-total Pb isochron ages in agreement with conventional U-Pb data. Monazites from four samples of post-Archean migmatite from the Ivory ...
-
(1990)Geochronological studies of a large number of precipitates from the TAG hydrothermal field and of few samples from Snakepit hydrothermal field of the Mid-Atlantic Ridge show intermittent repeated hydrothermal events at ...
-
(2004)The isotopic geochronology of a representative collection of moderately acidic volcanics from the Javakheti neovolcanic area in the northwest of the Lesser Caucasus (Georgia) is studied using the K–Ar and Rb–Sr methods. ...
-
(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 ...
-
(Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2019)This paper discusses the productive beds of the Urna and Ust-Tegus oil fields (West Siberia, Russian) and permeability and capacity properties that are influenced by geodynamic processes. Strong tectonic processes, accompanied ...
-
(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, ...
