-
(2004)The presented geochronologic and geochemical data provide full evidence for the following conclusions. 1) The obtained age estimate (2719±14 ma) corresponds to crystallization period for the rocks of the layered series of ...
-
(2002)Two types of organogenic structures of the Central Uralian Melekhov Horizon (Gzhelian Stage, Upper Carboniferous) contain essentially different schwagerinid assemblages. Owing to the diversity of its surface biotopes, the ...
-
(2003)Active deformation in the South Caspian region demonstrates the enormous variation in kinematics and structural style generated where a rigid basement block lies within a collision zone. Rigid basement to the South Caspian ...
-
(2003)Geometry and Late Cenozoic kinematics of regional and local active faults in the northern and western sides of the Hovsgol basin have been studied through remote sensing and geomorphological and structural field measurements. ...
-
(2004)The Arabia-Eurasia collision deforms an area of ∼3,000,000 km2 of continental crust, making it one of the largest regions of convergent deformation on Earth. There are now estimates for the active slip rates, total convergence ...
-
(2002)High-resolution clay mineralogical investigations and their comparison with other sedimentological data from ODP Sites 908 and 909 (central Fram Strait) were used to reconstruct the paleoclimate and paleoceanography in the ...
-
(2002)The Pamir indentor of the northwestern Himalayan syntaxis is a first-order feature demonstrating partly the northward extent of deformation due to the Cenozoic Indo-Eurasia collision. The Alai Valley of Kyrgyzstan at the ...
-
(1996)The Gobi Altai region of southwestern Mongolia is a natural laboratory for studying processes of active, transpressional, intracontinental mountain building at different stages of development. The region is structurally ...
-
(2001)Plio-Pleistocene acidic volcanism of the northeastern part of the Armenian highland is related to a continental collision zone as a result of convergence between Eurasia and Arabia lithosphere plates. The development of ...
-
(2002)Carbon stable-isotope stratigraphy provides unique insights into environmental change during the Campanian, the longest (83.5–71.3 Ma), but least well-understood stage of the Late Cretaceous. A new carbon isotope (δ13C) ...
-
(2003)We present palaeomagnetic results from Late Cretaceous welded tuffs in the Kisin Group (Monastirskaya Suite, Primorskaya Series) collected at 27 sites from the Sikhote Alin mountain range. A high unblocking temperature ...
-
LATE CRETACEOUS PALEOMAGNETIC DATA FROM THE MEDIAN RANGE OF KAMCHATKA, RUSSIA: TECTONIC IMPLICATIONS (1998)A Late Cretaceous island arc complex was sampled for paleomagnetic study in the northern part of the Median Range of Kamchatka. In most samples, thermal demagnetization in 12-18 steps revealed either a reversed characteristic ...
-
(2003)A new unit of the morphogenetic system, the stemma Duplocolpoidipolles, is established. In respect to the development of the germinative apparatus, the stemma immediately follows the stemma Duplospores Pflug., which embraces ...
-
(2003)In Russia Late Cretaceous Phaeodaria have been discovered for the first time. Two new species, Protocystis naibiensis sp. nov. and Challengeria (?) sakhalinica sp. nov., are described.
-
(1995)Welded tuffs in the Bogopol and Sijanov groups were sampled at 27 sites from 12 caldera formations in the Sikhote Alin mountain range around Kavalerovo (44.3°N, 135.0°E) for chronological and paleomagnetic studies. KAr age ...
-
(2002)The plate tectonic paradigm implies rigid plates and narrow plate boundaries. In contrast, diffuse plate boundaries are common both in the oceans and continents [R.G. Gordon, Annu. Rev. Earth Planet. Sci. 26 (1998) 615–642], ...
-
(2000)Widespread penecontemporaneous igneous activity affected NW Russia (the Kola Peninsula and adjoining areas to the SE around Arkhangelsk) during the Late Devonian (360–380 Ma). Magmatism varies from tholeiitic basalts, ...
-
(2003)Late Devonian is a crucial boundary in the evolution of the Uralian active margin of the East European Craton. This time is characterized by the beginning of collision of the East European continent with the Magnitogorsk ...
-
(2001)Late Devonian magmatism in the Pripyat Trough, Belarus was associated with the development of the intraplate Pripyat-Donets Palaeorift. Magmatic rocks belong to an alkali-ultrabasic-alkali-basaltoid suite. These are ...
-
(2003)A Late Devonian paleogeographic reconstruction for the territory of the West Siberian Plate and the surrounding regions of the Altai-Sayan folded area and the Siberian Platform has been proposed. Zones of continental, ...
