Meridional relations of Late Cretaceous marine biota of the Northern Hemisphere
The latitudinal climatic zonation complicates the realization of biostratigraphic comparisons on the south-north vector. At the same time, Upper Cretaceous biostratigraphic schemes of northern regions can be correlated to the International Startigraphic scheme only on the basis of precise meridional correlations. Among the conditions favourable to get over the climatic barriers were shallow-water epicontinental meridional seas-straits, which connected Paleoarctic basin with the Tethyan sea: the Western Interior Basin in North America and Turgay Strait – Western Siberian Sea system in Eurasia. The paper considers their specific features and formulates the proposals for future researches of meridional connections of Late Cretaceous marine biota.

Palaeotemperature curve for the Late Cretaceous of the northwestern Pacific (Hokkaido, Sakhalin, Eastern Koryakiya)
In the northwestern Pacific two main trends in the Late Cretaceous temperature change can be recognized. (1) In general, a recurrent warming trend is thought to have begun in the Turonian-Campanian, reaching temperature maxima in the early Late Santonian (19.6oC) and early Late Campanian (18.1oC), and temperature minima in the earliest Santonian (with an average of about 8.0oC) and perhaps early Campanian (not more than 13.3oC). (2) During the Maastrichtian, temperatures decreased sharply (up to 7.0oC), with only a slight relative warming in the early Late Maastrichtian. The existence of a thermal maximum at the Coniacian-Santonian boundary being previously postulated was not confirmed by new isotopic datings.

Jurassic – Early Cretaceous volcanic-chert complex of the Manoma river area, Northern Sikhote-Alin: a fragment of the paleooceanic plate sedimentary cover
The original stratigraphic sequence of the Early Jurassic – Early Cretaceous volcanic-chert formations of the Manoma river area, Kiselevka-Manoma terrane, was reconstructed on the basis of lithological study of the exposures and radiolarian dating. The Jurassic part of this section consists of platy red chert with layers of basic volcanic rocks and compact cherty breccias. Cretaceous layers contain a larger amount of clayey red chert and siliceous mudstones; chert-laminite and tuffites are less common. The deposits are about 300 m thick. In other areas of the Kiselevka-Manoma terrane the volcanic-chert complex has a similar composition and the same lithostratigraphic elements. It is correlated with analogous formations developed on the Sakhalin island and in Japan. Considerable age range (more than 100 Ma), small thickness (from the first hundreds of meters), association of pelagic deposits with intraplate oceanic volcanic rocks suggest that the complex is a fragment of an ancient ocean plate sedimentary cover.

Cretaceous pull-apart basins of South-East Korea: stratigraphy, facies, formation mechanism
In the southeastern Korean Peninsula, a series of epicontinental basins of the Hauterivian-Albian age occur along the Konju-Ymsong and Kwanju-Endong lef-lateral strike-slip zones. Judging from their geometry and facies distribution, they are typical pull-apart basins. The formation of the Cretaceous basins of Southeast Korea is closely related to the episodes of left-lateral strike-slip displacement activity along the Tan-Lu fault system. As a whole, the environment of the transform margin is reconstructed for the Early Cretaceous in this area of the East Asian margin.

A new Upper Cretaceous section in the Northern Sakhalin
A continuous 2400 m-thick section of Cretaceous deposits exposed by a parametric hole in the northern Sakhalin is described. Composition and physical parameters of rocks, mollusc and foraminifer remains have been studied. The section is correlated with other Cenonian sections from Sakhalin, Kamchatka and the Koryak Upland.

Stratigraphy of the Alchansky Cretaceous epicontinental basin (West Sikhote-Alin)
Aptian-Cenomanian deposits of the Alchansky basin and enclosing deposits of floral and faunal remains are described. Detailed analysis of facies composition and change in time of floral and faunal taxa allowed reconstruction of the environments in this region at the Early to Late Cretaceous boundary. Within the basin synsedimentation Guberovsky and Zmeino-Stolbovskoy grabens, and Silanshansky horst-anticline, separating them, which developed autonomously have been distinguished.

Faunal evidence of successive accretion of the Taukha terrane paleooceanic fragments (Southern Sikhote-Alin)
Based on the microfaunal study of the Gorbousha subterrane chert-clastic deposits, three successive radiolarian assemblages of different ages have been distinguished. They are Xitus gifuensis, Stichomitra doliolum and Pseudodictyomitra carpatica assemblages. The age of transitional layers from cherts to turbidites has been determined. Biostratigraphic data on the Gorbousha subterrane transitional layers from different regions suggest at least two-times recurrence of Gorbousha subterrane chert-terrigenous section within the Taukha accretionary prism resulting from paleooceanic plate successive accretion, but not from post-accretionary synfolding thrusts. A short description of radiolarian assemblages is given.

Stratigraphy and age of the continental deposits of Central and East Chukotka
Stratigraphy of volcanic sediments developed on the left side of the Palyvaam River and adjacent areas has been examined. It has been substantiated that the five members of the Chaun series, Central Chukotka, are of the Turonian–Coniacian age. The Chaun floral complex is considered as a single association.
Upper Cretaceous deposits along the middle reaches of the Amguema River and northern coast of the Krest Bay have been described for East Chukotka. From floral complexes established, the age of Nyrvakinot (Late Albian-Cenomanian, probably, Late Albian–Early Cenomanian) and Amgen (Turonian), Ekitykan (Coniacian), and Leurvaam (Santonian) suites has been determined. Flora of the Leurvaam suite is correlated with the Arkagalinsky floral complex of the Arkagala coal-bearing area.

Some Early Cretaceous ammonites from Sikhote Alin
Representatives of some Early Cretaceous ammonites from Sikhote Alin have been determined and figured. Totally 36 specimens were studied and 11 taxa were identified. These are representatives from four ammonite superfamilies: Desmocerataceae, Tetragonitaceae, Phyllocerataceae, and Turrilitaceae. Ddetail locations of all findings are shown. The most part of taxa is common with the Aptian – Albian and, in some cases, Early Cenomanian age of the containing deposits is confirmed.

On some Albian–Cenomanian Inoceramids from Northwestern Kamchatka, and their implications for correlation
Palaeontological material available from the Cretaceous deposits of the northwestern coast of Kamchatka has been analyzed. A new species Inoceramus omgonensis sp. nov. of Late Albian–Early Cenomanian age has been identified. The ways to correlate suites of the northwestern coast of Kamchatka and Cretaceous suites of stratotype region of the Penzhin basin have been outlined.
