(2003)A Cenozoic multi-species record of benthic foraminiferal calcite Sr/Ca has been produced and is corrected for inter-specific offsets (typically less than 0.3 mmol/mol) and for the linear relationship between decreasing ...
-
(2006)Major and trace element, whole rock Sr and Nd isotope and zircon Hf isotope data are reported for a suite of A-type granites and mafic microgranular enclaves from the Early Cretaceous (126 ± 2 Ma) Qianshan pluton, Liaodong ...
-
(2000)Remains of a heterosporous plant from the Late Cretaceous of the Tchulymo-Yenisey Basin, Western Siberia, are peculiar in having solitary sporangia on the laminar sporophyll pinnules. The sporangia produce a large number ...
-
(2001)Multituberculates are the best represented mammals of the Late Cretaceous in Asia and most of them are from Outer Mongolia. The djadochtatherioidean multituberculate Kryptobaatar mandahuensis n. sp. is described on the ...
-
(1998)We collected 47 sites of Upper Triassic to Middle Jurassic siltstones and sandstones and two sites of Lower Cretaceous andesites in a large basin located south of the Mongol–Okhotsk suture. The suture separates the Siberian ...
-
(1992)From the unique perspective of the geological record, it appears that the ‘Greenhouse Earth’ was a feature of climate for up to 80 % of the last 500 Ma, and that therefore our present glacially dominated climate is an ...
-
(2001)The Early Cretaceous is rapidly being recognized as a crucial time in the origin and dispersal of living vertebrate groups. Cretaceous trackways in Korea are among the most abundant in the world and include the smallest ...
-
(2004)We report a detailed rock magnetic and Thellier paleointensity study from Autlan volcanic succession in western Mexico. The whole rock K-Ar age obtained for these lavas, 67.4 ± 1.2 Ma, together with the magnetostratigraphy ...
-
(2003)Acid rain from the Cretaceous-Tertiary (K-T) boundary impact event should have caused significant damage to freshwater life, but only minor extinctions of freshwater species are actually observed. We propose a mechanism ...
-
(1990)87Sr/86Sr ratios, trace element and REE compositions, and textural characteristics were determined for three hydrogenetic Fe-Mn crusts, one hydrothermal deposit, and two mixed hydrothermalhydrogenetic crusts from the ...
-
(1989)The first occurrences of lamproites in Soviet Union were identified on the Aldan Shield, in the region of the Murun Pluton and in the Central Aldan block. By the geological position of the lamproite bodies and the geological ...
-
(1999)Different views on the composition and stratigraphic succession of the Cretaceous floras in northeastern Asia are considered. These floras populated different landscapes of that time and their correlation are difficult to ...
-
(2004)The stratigraphy and ammonite faunas of the Cretaceous succession in Sakhalin are discussed. A high-resolution bio-stratigraphic zonation (24 zones in total) is proposed; it is correlated with adjacent areas and corresponds ...
-
(2006)The precise cause and timing of the Cretaceous-Paleocene (K-P) mass extinction 65 Ma ago remains a matter of debate. Many advocate that the extinction was caused by a meteorite impact at Chicxulub, Mexico, and a number of ...
-
(2006)We present new palaeomagnetic results from Late Cretaceous red beds of the Paomagang Formation collected at 42 sites in the Yichang area (30.7°N, 111.7°E), middle-northern part of the South China Block. A high unblocking ...
-
(2006)Twenty-six groundwater samples were collected from the Eastern Thessaly region and analysed by ICP-ES for these elements: Al, As, P, Pb, Zn, Mn, Fe, Cr, Sb, Cu, Na, Br, Cl, Si, Mg, Ag, Be, Bi, Dy, Er, Eu, Au, Ge, Ho, In, ...
-
(2006)Complex bio- and magnetostratigraphic studies of Lower Cretaceous deposits in the central Volga region, Northern Caucasus, and other regions carried out by the authors of the present communication for more than 10 years ...
-
(1997)About 10,000 years ago, at the Pleistocene-Holocene border, some important events occurred: the glaciation stopped abruptly; the sea level elevated, and quick (for 20-50 years) climatic and ecological changes took place, ...
-
(2006)The Baimazhai Ni-Cu-PGE (platinum-group-elements) sulfide deposit, southeast Yunnan Province, is hosted in mafic-ultramafic intrusions of the Permian Emeishan large igneous province, with which it is temporally and genetically ...
-
(2003)A new horned dinosaur, Bainoceratops efremovi gen. et sp. nov., is described on the basis of vertebral series from the well-known Bain-Dzak locality (Mongolia). The new form is distinguished from Protoceratops andrewsi ...
