-
(2003)Fossil bivalves bearing oblique ribs first appeared in the Mid Ordovician but their diversity remained low during the Palaeozoic. The diversity soon increased after the Early Triassic, peaking in the Early Cretaceous. The ...
-
(2006)Large submarine canyons incise most continental margins, but outcrops of comparably sized ancient examples are relatively rare. A preserved cross section of a filled Cretaceous-Paleocene submarine canyon, tens of kilometers ...
-
(2004)In the northeastern Peri Tethys, the Goryachii Klyuch facies of the upper Paleocene are much more widespread than it was believed before. The facies correspond to dark colored, predominantly carbonate-free sediments bearing ...
-
(1997)This is the first reliable record of the genus Platanus based on pistillate heads and leaves from the Paleocene of Western Kamchatka. The leaves were previously described as P. basicordata Budants. A new species, P. ...
-
(2006)Rock-Eval pyrolysis and microscopic analyses of Palaeogene terrestrial strata from the western Kamchatka coastal margin, Russia, indicate that good oil-prone source rocks are present in both coals and shales. Hydrogen ...
-
(2003)Pre-Quaternary terrestrial climate records in which time has been calibrated using astronomical cycles are, with the exception of lacustrine proxies, poorly represented in the geological record. This omission is a significant ...
-
(2006)The uplifted plutons of the eastern Coast Plutonic Complex (CPC) of the northern Canadian Cordillera are in contact with coeval volcanic suites of the early Tertiary Sloko-Skukum Group, offering a unique opportunity to ...
-
(2002)We present paleomagnetic results of Paleocene welded tuffs of the 53–50 Ma Bogopol Group from the northern region (46°N, 137°E) of the Sikhote Alin volcanic belt. Characteristic paleomagnetic directions with high unblocking ...
-
(2006)The Izmir-Ankara-Erzincar suture zone (IAESZ) in the Central and the Eastern Pontides comprises a stack of thrust sheets of mainly Late Cretaceous-Early Cenozoic age that are restored as: (1) a subduction-accretion complex; ...
-
(2006)The Outer Carpathian Basin domain developed in its initial stage as a Jurassic-Early Cretaceous rifted passive margin that faced the eastern parts of the oceanic Alpine Tethys. Following closure of this oceanic basin during ...
-
(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 ...
-
(2004)Taphofloras of the Koryak Upland and the Sagwon Locality of North Alaska are described in terms of their taxonomic composition, stratigraphic ranges, and comparison with coeval floras of Northeastern Russia and Alaska. ...
-
(2006)The tectonic evolution of the Rhodope massif involves Mid-Cretaceous contractional deformation and protracted Oligocene and Miocene extension. We present structural, kinematic and strain data on the Kesebir-Kardamos dome ...
-
(2006)Talc deposits, located mainly in three areas of north-central Turkey, are present in the ophiolitic series of the Cretaceous and in siliciclastic rocks of the Paleocene. Talc deposits related to ophiolites are between ...
-
(2002)Neocassandra mica Daniltshenko, 1968 from the Late Paleocene of Turkmenistan is revised and assigned to the order Aulopiformes. However, it substantially differs from all members of the order in the following characters: ...
-
(2003)A new monotypic genus, Archaranthus gen. nov. (Platanaceae) with A. krassilovii sp. nov. as its type species, is erected for staminate inflorescences from the Maastrichtian-Paleocene deposits of the Amur Region on the basis ...
-
(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 Paleocene, most of the present West Siberian plain was occupied by a vast epicontinental sea, which reached from the present Arctic and Atlantic oceans in the North to the Aral Basin in the South. Climate and ocean ...
-
(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 ...
