...V.S. Volkova Abstract The paper is concerned with the structure of the Arctic shelf sediments in the Ob’ region in the Paleogene and Neogene, sampled from boreholes drilled on the Yamal Peninsula, in the lower reaches of the Pur and Taz Rivers. The specifics of Paleogene marine sedimentation...

.... Deposits with similar associations were exposed by BH-38 in the center of the Taz Peninsula at depths of 194–150 m below the Ob’ River level. Pollen is unevenly distributed in the sediments. One half of the sequence contains occasional spores and pollen grains. The other half contains notable amounts...

...F.I. Enikeev Abstract Paleogeographic reconstructions for the Samarovo, Taz, Murukta, and Sartan glaciations reveal the formation conditions of proglacial lakes dammed by ice in intermontane depressions and valleys of large rivers in eastern Transbaikalia. Middle–Late Pleistocene climate change...

... in the Touro Passo River, dead shells are rapidly destroyed at the TAZ (also characterized by a subtropical climatic condition). Thus, the fossilization potential of the present-day shells in the Touro Passo River death assemblage was low or extremely improbable. Hence, those shells might have a low residence...

... ( Figs. 1 and 2 ), the Kazantsevo marine deposits with the Kazantsevo complex of foraminifers are situated between the Taz and Ermakovo (Lower Zyrjanka) moraines, as it is established on the lower reaches of the Ob’ River, in the Salekhard reference terrain, as well as in the section of BH-4 drilled...

... (Pustoe and Karapovskoe winter stations), and in northern Yamal [ 34 ]. The portland transgression did not reach the Yenisei valley. Its traces are absent from the entire territory from Taz River to Putorana Plateau. In the valley of the lower and middle Ob’, the upper stage appears as the Kolpashevo...

...Fig. 8. Areal boundaries of the Sanchugovka-Salemal sea and the Taz glaciation. 1 –Sanchugovka-Salemal paleobasin, marine sediments; 2 – southern boundary of the transgression; 3 – gulfs and deltas; 4 – river valleys, alluvial, mainly sandy deposits; 5 – the bound of the maximum...

.... The Tobol’ River from the southwest and the Irtysh River from the south join the Ob’River from the southeast near the middle of the basin. The Ob’ flows northward along the west side of the basin to the Arctic Ocean. The northeast part is drained by the Pur and Taz Rivers. Some geologists believe the basin...

... characteristics relative to residence times within the TAZ and above the DFB. Note that contours of all plots except skewness (D and G) are logarithmic. Dashed lines represent depression contours. Shaded areas indicate the extreme values of standard deviation and skewness for shell ages from Colorado River Delta...

... in the subsurface SZ is one long-suspected means of increasing the persistence of shells exhumed back to the TAZ through Ostwald ripening (crystallite coarsening), mineral coatings, or micritization both in siliciclastic and carbonate environments (Jenkyns 1975 ; Kidwell 1989 ; Reid et al. 1990 ; Rivers et al...

... lower reaches of the Ob’ and Yenisei Rivers. The main glacier features are the Ob’, Polui, Nadym, Pur, Taz, and Yenisei lobes ( Fig. 4 ). The orientation of glaciodepressions and bands of marginal glacier formations, outlining them in an arch-like fashion from the south, indicates that within three...

... molluscs from the Taphonomically Active Zone (TAZ) in marine core SV#23, Gulf St. Vincent. The results of some earlier gas chromatography analyses are also reported in this work relating to a marine vibracore from southern Gulf St. Vincent, southern South Australia (next section). The analytical...
