In our original theory of ice ages (1) we proposed that Quaternary glaciation is initiated by the migration of the geographic poles to regions of thermal isolation-that is, to the Arctic Ocean and Antarctica. Glacial-interglacial alternations were explained by the variability in the moisture supply for glacial growth, a variability resulting from the alternations of ice-covered with ice-free states of the Arctic Ocean.Although we still adhere to the fundamentals of this twofold model, important modifications have been made on the basis of new material that has become available. The changes in the model which apply to the glacialinterglacial aspect are, in summary, as follows: (i) the freezing of the Arctic Ocean surface, initially postulated to have occurred at the termination of a glacial stage (about 11,000 years ago in the case of the Wisconsin, or Wuirm, stage) must have occurred considerably earlier; (ii) the moisture source for the growth of the southern half of the North American ice sheet must have been, not the Arctic Ocean, but the rich southerly source usually assumed for the growth of the entire ice sheet; (iii) the termination of a glacial stage is a consequence of a dearth of atmospheric moisture for precipitation-a dearth caused by glacial growth rather than by freezing of the Arctic Ocean surface as a result of the lowering of sea level below some critical sill depth, as originally postulated.Our purpose in this article is to present the revised theory, including a discussion of the time of onset of glaciation and a consideration of the heat Dr.

“…) to relate the observed differences in the positions of the paleomag netic poles of the coeval rocks of the different (tecton ically incoherent) crustal blocks, including the conti nental ones, to the continental drift have faced exten sive criticism. A particular focus of the criticism laid in the accuracy and datings of the paleomagnetic deter minations (Rezanov, 1961;1968;Meyerhoff, 1979). The conclusion of these authors was quite cer tain: "…the paleomagnetic determinations have been so inaccurate and controversial that they cannot be used as arguments validating or refuting the hypothesis of the relative displacements of continents or their parts" (Rezanov, 1968, p. 47).…”

The analysis of Meso–Cenozoic paleomagnetic poles and the apparent polar wander path of Siberia

The Meso Cenozoic paleomagnetic data for the Siberian Platform and its closest folded framing are analyzed for compliance with four criteria: structural tectonic coherence, the accuracy of dating the rocks and the corresponding characteristic component, quality assurance of the paleomagnetic field and lab oratory procedures, and the degree of grouping of the characteristic components around the mean. It is estab lished that (1) the reliable paleomagnetic data are highly nonuniformly distributed in time. The intervals 0-60, 80-120, and 180-220 Ma lack any paleomagnetically reliable poles. Three intervals (60-80, 160-180, and 220-240 Ma) are only characterized by a single reliable pole for each interval. Two intervals (120-140 and 140-160 Ma) have three reliable poles for each of them. The largest number of the reliable paleo magnetic poles (29) falls in the interval 243-251 Ma.(2) The analysis of the paleomagnetic data for the Mesozoic of the Siberian Platform, the Mesozoic segment of the apparent polar wander path (APWP) con structed from these data, and its comparison with the global APWP curve in the coordinates of stable Europe (Torsvik et al., 2008) discredit the hypothesis of the tectonic incoherence between Siberia and stable Europe throughout the Mesozoic. The available paleomagnetic data are in favour of complete tectonic coherence of the Siberia Platform and stable Europe from the Late Jurassic (150 Ma). The position of the Triassic poles of Siberia relative to the coeval poles of the global APWP in the coordinates of stable Europe suggests a clockwise rotation of the former relative to the latter by at least 14°-15°, which probably took place in the Late Triassic.
