(2001)This paper presents a considerably revised biostratigraphy for Upper Albian through Coniacian pelagic limestone and shale sequences in the northeastern Caucasus region based primarily on planktic foraminiferal distributions. ...
-
(1988)Because commercial fluorite mineralization in the southern Tien Shan was deposited in late Hercynian and early Alpine metallogenic epochs, the numerous finds here of fluorite occurrences dating from late Alpine time were ...
-
(PANGAEA, 1999-10-22)On the Taymyr Peninsula and Severnaya Zemlya Archipelago, Central Siberia, a joint German/Russian multidisciplinary research project focuses on the Late Quaternary history of climate and environment. Within the scope of ...
-
(2004)Geological mapping showed that the northeastern part of the Belomorian mobile belt consists of metamorphic rocks (amphibolites and schists) and plagiogneisses resting on a granite basement. The close spatial association ...
-
(2004)Late Archean rocks of the North Karelian system of greenstone belts and overlying Early Proterozoic sequence of the Kukasozero structure provide insights into the entire evolution of Early Precambrian tectonogenesis and ...
-
(2004)This paper presents new data on the age and composition of granitoids from the Charnokitovyǐ and Drevnestanovoy complexes of the Dambukinskiǐ block in the eastern Dzhugdzhur-Stanovoy fold belt. Based on the results of U-Pb ...
-
(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 ...
-
(2006)Component natural remanent magnetizations derived from u-channel and 1-cm3 discrete samples from ODP Site 919 (Irminger Basin) indicate the existence of four intervals of negative inclinations in the upper Brunhes Chronozone. ...
-
(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 ...
