(2002)New data prove that a major rise in the Baikal water level (to 120-150 m) in the Middle Pleistocene may have been caused by tectonic uplift of the western side of the Baikal basin and is marked by medium and high terraces ...
-
(2003)We report Thellier paleointensity results from single plagioclase crystals derived from ca. 2.45 Ga border dikes of the Burakovka layered intrusion (Karelia, Russia). Rock magnetic and transmission electron microscope ...
-
(2002)Research of the past 15 years has reported the manifestations of seismically induced liquefaction that occur in the sedimentary conditions commonly found in continental settings. And, criteria have been developed and ...
-
(2003)This paper presents a new methodology for studying the evolution of curved mountain belts by means of paleomagnetic analyses performed on analogue models. Eleven models were designed aimed at reproducing various tectonic ...
-
(2006)Closure of the Neo-Tethyan Ocean in the Turkish sector of the Alpine-Himalayan orogen by ca. 12 Ma was succeeded by deformation of a domain between the Eurasia plate, presently bounded by the North Anatolian fault, and the ...
-
(2006)A combined geochronological and paleomagnetic study is reported from Miocene basalts from Halaqiaola and Paleocene to Eocene red beds from Fuyun at the southern Altai Mountains, northern Xinjiang. Three new 40Ar/39 Ar ages ...
-
(1999)The Eocene to Lower Miocene strata in the Bykov region of south Sakhalin Island, Far East Russia, show a mean paleomagnetic direction of Dec. = 28.7°, Inc. = 55.7°, α95=6.7, and N=22, and a paleomagnetic pole at 66.3°N, ...
-
(2002)The Omolon massif in northeastern Russia forms the core of the Kolyma-Omolon superterrane. The massif has an early Precambrian crystalline basement and is surrounded by the Paleozoic shelf deposits of the Omulevka terrane ...
-
(2002)Paleomagnetic and rock-magnetic studies on a hydraulic piston core (Ver98-1, St.6) from Academician Ridge, Lake Baikal showed the occurrence of a reversal excursion at 670–696 cm depth, which is at the base of marine oxygen ...
-
(2006)At least two supercontinents - Rodinia and Gondwana - have been proposed for the 1200-500 Ma time interval on the basis of stratigraphic, geochronological and paleomagnetic grounds. Although the exact configuration of ...
-
PALEOMAGNETIC REFERENCE INTERVALS OF THE LATE PLEISTOCENE IN THE CENTRAL AREA OF THE RUSSIAN PLAIN (1988)In the Pleistocene, which is encompassed entirely by the 0.73 million years long Brunhes paleomagnetic epoch, paleomagnetic episodes such as the Blake Espisode cannot be reliably traced. As a result, efforts to improve the ...
-
(2002)This paper presents new paleomagnetic results on Cenozoic rocks from northern central Asia. Eighteen sites were sampled in Pliocene to Miocene clays and sandy clays of the Zaisan basin (southeastern Kazakhstan) and 12 sites ...
-
(2001)Where tectonic deformation reorients rocks without penetrative strain, their paleomagnetic vectors may be restored to their original attitudes by untilting. For strata, paleomagnetic inclination is readily restored but the ...
-
(1995)The Siberian traps were emplaced near the Permo-Triassic boundary and are among the largest continental igneous provinces. A 1750 m thick section of traps from the western Taimyr (72.9°N, 84°E) has been sampled. This section ...
-
(2006)Paleomagnetic, rock magnetic, and petrophysical results are presented for impactites and target rocks from the Lake Jänisjärvi impact structure, Russian Karelia. The impactites (tagamites, suevites, and lithic breccias) ...
-
(2006)The Ionian zone is a classic thin-skinned linear fold and thrust belt forming a part of the external Hellenides, in westernmost Greece. The region has been a focus of intensive paleomagnetic investigation since the early ...
-
(1991)A stable and well defined magnetization with D = 350°, I = 55.5° and alpha95 = 4°, carried by hematite, is isolated in the red beds of the Tajik basin. The fold test is positive (99% probability) and this magnetization ...
-
(2001)The Hokkaido-Sakhalin fold system stretches for ~˜1500 km along the eastern coast of Asia and consists of several N-S trending tectonic belts. Studies in South Sakhalin show that the northern part of the Tonino-Aniva ...
-
(1994)We have carried out structural and paleomagnetic studies in the Tadzhik depression in order to evaluate the main features of the Alpine tectonics of this area. About 340 cores from 43 sites of Lower Cretaceous red beds ...
