A 900-Years Larch Chronology for North-Western Siberia on the Bases of Archaeological Wood of the UST-Voykar SettlementDuring 2003-2006 summer excavation seasons of the Ust-Voykar settlement (65°40' N, 64°30' E) located in northwestern Siberia on the left bank of Gornaya Ob river, 121 samples of larch were collected. Living trees collected nearby were used to cross-date settlement construction. On the basis of living larch trees a 446 year (1554-1999) chronology has been constructed. Calendar dates for 101 samples of archaeological wood were established by cross-dating. Together, the living and archeological material result in a 903 year long chronology. This chronology shows similar variations as the Yamal and Polar Ural chronologies and provides new material that can be included in future climatic reconstructions.

Abstract This study is focused on the quantification of dust load on snow cover and chemical elements content in the solid phase of snow cover in the impacted areas of cement plants (the south of Western Siberia). Applying the instrumental neutron activation analysis, we identified chemical composition in the samples of the solid phase of snow cover. The results demonstrated that the dust load corresponded to the permissible pollution levels in the living zones. Dust pollution level varied from moderately hazardous to highly hazardous in the north-western impacted zone of the cement plants and raw material open pits. It was found that the predominant chemical element is Ca, as well as a group of rare-earth (Yb, Tb, Sm, La, Ce, etc.) elements in the solid phase of snow cover from the impacted zone of the cement plants.

Blattinopsis indefinitus Rasnitsyn et Aristov, sp. n. is described from the Lower Permian Fokina locality (the upper Burgukla subhorizont of the upper Kungurian Stage) in North-Western Siberia. It is the latest record of the genus Blattinopsis Giebel, 1867.
