“…In the Southern Verkhoyansk region, 300 m of limestones and dolomites were accumulated under marine conditions (Ronov et al 1984;Zonenshain et al 1990;Parfenov 1991;Prokopiev 2000). In the central part of the Siberian craton a large Tunguska Basin existed in the Early Ordovician (Ronov et al 1984;Kanygin et al 1988;Zonenshain et al 1990;Bogolepova et al 2006;Artyushkov et al 2008;Fig. 6.7).…”

“…6.9). A fraction of carbonates in the deposits decreased (in the Tunguska and Southern Taymyr basins), while the fraction of terrigeneous sediments increased (Ronov et al 1984;Kanygin et al 1988;Zonenshain et al 1990;Torsvik et al 1995;Bogolepova et al 2006;Artyushkov et al 2008). In the eastern Tunguska Basin, gypsum layers and lenses indicate increased water salinity.…”

Sixty-three maps illustrate geodynamic evolution and development of palaeoenvironments and palaeolithofacies of the Circum-Arctic region during Phanerozoic times. After the break-up of Rodinia and Pannotia in the Early Palaeozoic, the major Arctic plates Baltica, Siberia and Laurentia drifted from their original position around the South Pole towards the Supercontinent Pangea, which existed in the equatorial position during Late Palaeozoic and Early Mesozoic times. During the Mesozoic and Cenozoic plates gathered around newly formed Arctic Ocean. Large continental masses were assembled from major plates and numerous small plates and terranes on the northern hemisphere and around the North Pole. All the continents were by now connected. Carbonates were abundant in Siberia and Laurentia during Palaeozoic times. Clastic sedimentation prevailed during Mesozoic and Cenozoic times. The distribution of lithofacies shows climatic change associated with continental assembly and disassembly as well as with the steady northward drift of the continents.

“…Bogolepova and A. Gubanov http://www.cambridge.org/journals/geo). A summary of the litho-and biostratigraphy of the Ordovician strata has recently been published (Bogolepova, Gubanov & Pease, 2006), and several Silurian (Telychian) faunas with their palaeogeographical implications have been discussed (Bogolepova, Gubanov & Loydell, 2000;Högström, Bogolepova & Gubanov, 2002;Bogolepova, Gubanov & Pease, 2005;Siveter & Bogolepova, 2006). The aim of the present paper is to give an overview of the conodonts discovered after processing the samples from the sections studied in 1999 and to discuss the stratigraphy of the region based on these new data.…”

Thirty samples from 22 sections collected by the SWEDARCTIC international expedition to Severnaya Zemlya in 1999 contained Ordovician and Silurian conodont faunas. Several taxa, including Apsidognathus cf. milleri, Aulacognathus cf. kuehni, Nudibelodina sensitiva, Ozarkodina broenlundi and Pterospathodus eopennatus, allow precise dating of the strata in this region for the first time. The occurrence of Aphelognathus pyramidalis and Rhipidognathus aff. R. symmetricus in samples from the Strojnaya Formation fits well with the earlier dating of these strata as latest Ordovician. However, Aphelognathus sp. in sample BG-99/14-a, collected from the upper Ushakov Formation, indicates that at least in the lower reaches of the Ushakov River the top of this formation is considerably younger than considered earlier: the sampled strata are Late, not Early Ordovician in age. In the Ordovician and Silurian the present-day Severnaya Zemlya region was dominated by extensive shallow-water, mainly semi-restricted basin environments with habitat specific faunas. The occurrence of Riphidognathus aff. R. symmetricus at some levels in the Upper Ordovician suggests extreme shallowing episodes in the basin. On Severnaya Zemlya, 'normal-marine' faunas (including Pt. eopennatus) invaded the distal peripheral regions of the wide shallow-water platform at times of maximum sea-level rise only. The occurrence of Oz. broenlundi and N. sensitiva indicates that in the early Silurian the Severnaya Zemlya basin was quite well connected to the basins over modern North Greenland as well as to the Baltic Palaeobasin. The lower Silurian conodont assemblages in the Vodopad to Samojlovich formations are most similar to those described from the eastern Timan-northern Ural region.
