(2000)Late Eocene microtektites and crystal-bearing microkrystites extracted from DSDP and ODP cores from the Atlantic, Pacific, and Indian oceans have been analyzed to address their provenance. A new analysis of Nd and Sr ...
-
(2001)The results of a quantitative palynological analysis, emphasizing organic-walled dinoflagellate cysts (dinocysts), of Palaeocene–Eocene deposits exposed in the Sokolovsky Quarry (Turgay Trough, Northern Kazakhstan) are ...
-
(2003)To further understand the distribution and abundance of Apectodinium through space and time, dinoflagellate cyst (dinocyst) records from two well-calibrated Paleogene sections in the Tethys (Tunisia and Uzbekistan) have ...
-
(2001)I present a new method for reconnaissance cyclostratigraphic study of continuously cored boreholes: the generation of detailed sediment color logs by digitizing Ocean Drilling Program (ODP) core photographs. The reliability ...
-
(1989)Igneous activity is a very accurate indicator linking the surface of the Earth to its crust and mantle. Features indicative of the general heterogeneity of the lithosphere include great magmatic 'seams', many thousands of ...
-
(2003)In thе lаtе middlе tо еarliеst latе Еoсеnе, a vast dysохiс to anoхiс bаsin еxtеndеd from thе Сrimеа in thе Wеst through thе northеrn Cauсasus to thе Aгal Sеа in thе Еast' and a hugе amount оf organiс сarbon was dеpositеd ...
-
(2003)Observations of living Cernina fluctuata (Sowerby), the sole extant species of the Mesozoic and Cenozoic prosobranch gastropod family Ampullospiridae, show that this species is an algal grazer and is not a shell-drilling, ...
-
(1985)Episodic volcanism favors, as shown by examples from Europe, the USA, and Brazil, the formation of organic-rich sediments (hydrocarbon source rocks). The examples examined from Europe comprise the Lower Carboniferous ...
-
(1998)Assemblages of spores, pollen, and organic-walled phytoplankton were studied in the Middle Eocene-Oligocene sequence of Severnye Ergeni. The dinocyst zonal assemblages were described, and anomalies in their composition ...
-
(2004)Seven new species of gall midges belonging to the genera Strobliella, Campylomyza, Neurolyga, Diadocidia , and Camptomyia are described from the Eocene Rovno amber.
-
(1989)Our work gave new paleontologic and radiometric data on the age of the sedimentary, volcanogenic-sedimentary and igneous rocks in the structurally most complex northern part of Bering Island, which supplement existing ...
-
(1999)Remains of Macropterodon zelenovi, gen. et sp. nov. a very large representative of Hyaenodontinae (the size of Hyainailouros), and of a representative of the Proviverrinae gen. et sp. indet., (the size of Dissopsalis and ...
-
(2004)Two new palaeoryctids from the Eocene Asiatic genus Nuryctes are described. N. alayensis sp. nov. (terminal Lower Eocene, Alai Beds, Andarak 2 locality, Kyrgyzstan) is more primitive in the extent of premolar reduction ...
-
(2004)Fossil beetles of the family Ptiliidae are reviewed. Two new species, Micridium groehni sp. nov. and Ptinella rovnoensis sp. nov., are described from the Baltic and Rovno amber.
-
(1990)The origin of the Central Asiatic mountain belt is treated nowadays from two opposing points of view. Some researchers believe that it is a consequence of the collision of the Indo-Australian and Eurasian lithospheric ...
-
(1996)The vertical distribution of macrofossils (echinoids, biyozoans, brachiopods, bivalves, and others), and planktonic and benthic foraminifers was studied in several Paleocene and Eocene sections of western Mangyshlak. The ...
-
(2003)In the northeastern Peri-Tethys epicontinental basin stretching from the Black Sea to Tadjikistan, a sapropelitic bed with total organic carbon (TOC) contents up to 20% and enriched in redox-sensitive elements was deposited ...
-
(2001)Lithology, microfossils, and stratigraphy of the uppermost Paleocene - lowermost Eocene predominantly terrigenous and siliceous sediments from the Sokolovskii section located in the Turgay Passage, northern Kazakhstan, ...
-
(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, ...
