(2003)Information on Paleocene deposits of Western Siberia is scarce and fragmental. The palynological analysis of new materials is important therefore, and the data obtained can be used in stratigraphy and for interregional ...
-
(1996)Success in establishing high precision crystallization ages with the U/Pb zircon method is highly dependent on the ability to isolate or remove the effects of inherited xenocrystic components or secondary lead-loss, or the ...
-
(2003)Prominent negative δ13C excursions characterize several past intervals of abrupt (<100 kyr) environmental change. These anomalies, best exemplified by the >2.5‰ drop across the Paleocene/Eocene thermal maximum (PETM) ca. ...
-
(2004)In several recent papers, M.-P. Aubry et al. have argued that “Hedbergian” principles of chronostratigraphy are being violated by the International Commission on Stratigraphy (ICS) when selecting Global Stratotype Sections ...
-
(2000)In the southwestern Crimean Mountains, the lower Paleocene deposits (from 40-45 to 80-85 m thick) are perfectly exposed and fully characterized by macro- and microfossils. Two parts of the sequence are sharply different ...
-
(2003)Data on a series of boreholes drilled in the central trans-Urals are used to characterize the Paleocene marine deposits of the Talitsa Horizon, which are widespread all over the trans-Urals and in West Siberia. Presented ...
-
(1998)Data on stratigraphy and foraminifers from the Paleocene and Eocene deposits in western Siberia are correlated and the boundaries between the two series are verified. New results for boreholes 1, 2, 3, and 4 on the Kaimysov ...
-
(2004)For several hours following the Chicxulub impact, the entire Earth was bathed with intense infrared radiation from ballistically reentering ejecta. The global heat pulse would have killed unsheltered organisms directly and ...
-
(2001)A lower jaw containing complete tooth rows of the earliest hapalodectid mesonychian, Hapalodectes dux sp. nov., is described from the Upper Paleocene of Tsagan-Khushu, Mongolia (Naran Bulak Formation, Zhigden Member). The ...
-
(2004)Gobigeolabis verigranum gen. et sp. nov. is described based on jaw fragments from the Upper Paleocene Zhigden Member of the Naran Bulak Formation of the Tsagan-Khushu locality (Mongolia). This is the first Asian member of ...
-
(2001)In the Upper Paleocene sedimentary sequence of the Eastern Peritethys, there is a bed highly enriched in organic matter (sapropel). Investigation of microbiota, mainly of foraminifers, showed that the bed accumulated in ...
-
(2004)Upper Cretaceous and Lower Paleocene deposits of the Kronotskii Peninsula and their foraminiferal and radiolarian faunas are considered. As is shown, marine sedimentation during the Late Cretaceous - Early Paleocene was ...
-
(2000)We studied two sections that accumulated during the Paleocene–Eocene transition in shelf waters in the northeastern Tethys. Stable carbon isotopic compositions of marine and terrestrial biomarkers are consistent with a 13C ...
-
(2001)An almost complete skull with teeth of Archaeoryctes euryalis sp. nov., one of the earliest members of the family Didymoconidae, is described from the Tsagan-Khushu locality in Mongolia (Upper Paleocene, Naran Bulak ...
-
(2011)Арманская флора происходит из вулканогенно-осадочных отложений арманской свиты бассейна р. Армань и нараулийской свиты междуречья Нельканджа Хасын. В состав флоры входят 82 вида ископаемых растений, относящихся к печеночникам, ...
-
(1999)Аутигенные минералы цемента являются хорошими индикаторами среды осадконакопления и процессов преобразования осадков от начала их захоронения до глубинных степеней метаморфизма. В окраинных морях они пока не исследованы, ...
-
(2018)Результаты проведенного геохронологического, петролого-минералогического и изотопно-геохимического изучения Танадонского золоторудного месторождения на Большом Кавказе (Республика Северная Осетия – Алания) позволили ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Московский государственный университет им. М. В. Ломоносова», 2011)На северном крыле складчатого сооружения Северо-Западного Кавказа в долине р. Убинка установлена мощная олистостромовая толща позднепалеоцен-раннеэоценового возраста, что свидетельствует о значительной роли раннекайнозойских ...
-
(2003)Изучен литологический состав и фациальные особенности шельфовых отложений головнинской свиты о. Кунашир, которые могут служить промежуточным звеном при корреляции осадков окраинных морей и Тихого океана. На основании ...
-
(Томский политехнический университет, 2010)Изучены отпечатки голосеменных растений, впервые обнаруженные из отложений палеоцена-эоцена на юго-востоке Западной Сибири (район г. Томска). Приведена полная систематика голосеменных растений. Показано, что новое ...
