“…Similarly, new high precision U -Pb zircon ages of numerous ash layers in the Donets basin (Davydov et al 2010) are consistent with the classic interpretation of shallow marine to continental sequences of Carboniferous age in terms of astronomical forcing and glacio-eustatic sea-level change (e.g. Heckel 1986;Heckel et al 2007). …”

“…Anderson (1982Anderson ( , 2011 used annual laminae thickness counts to interpret Milankovitch forcing of more than 260 000 marine evaporite varves in the Late Permian (Ochoan) Castile Formation. Classical shallow marine cyclothems of the Carboniferous have been related to the c. 100 kyr and especially 405 kyr eccentricity cycles (Heckel 1986(Heckel , 1994. They have been correlated from the Donets Basin in the Ukraine to their North American counterparts, suggesting a global forcing mechanism of sea level at Milankovitch timescales (Davydov et al 2010;Martin et al 2012).…”

The Milankovitch theory of climate change is widely accepted, but the registration of the climate changes in the stratigraphic record and their use in building high-resolution astronomically tuned timescales has been disputed due to the complex and fragmentary nature of the stratigraphic record. However, results of time series analysis and consistency with independent magnetobiostratigraphic and/or radio-isotopic age models show that Milankovitch cycles are recorded not only in deep marine and lacustrine successions, but also in ice cores and speleothems, and in eolian and fluvial successions. Integrated stratigraphic studies further provide evidence for continuous sedimentation at Milankovitch time scales (10 4 years up to 10 6 years). This combined approach also shows that strict application of statistical confidence limits in spectral analysis to verify astronomical forcing in climate proxy records is not fully justified and may lead to false negatives. This is in contrast to recent claims that failure to apply strict statistical standards can lead to false positives in the search for periodic signals. Finally, and contrary to the argument that

“…Cyclothemic deposition is recognized as representing rapid and high-magnitude fluctuations in sea level, linked to global climate change (Heckel, 1986(Heckel, , 1995. The ultimate drivers of these changing climates, which appear to have been controlled by Milankovitch-scale orbital parameters, remain conjectural (Montailez and Soreghan, 2006).…”

“…The duration of the classical midcontinent cyclotherms is estimated to approximately 400 kyr (Heckel, 1986), capped cycles overprinted by Microcodium. It is relatively uniform in thickness across the study area, 75-84 m, being thickest in the distal localities towards the west and thinnest in the crestal areas along Billefjorden.…”

This paper presents the first comprehensive study of the Wordiekammen carbonate platform on the Nordfjorden High, Central Spitsbergen. The Wordiekammen succession is divided into four depositional sequences bounded by subaerial exposure surfaces and consists of 12-84 m-thick wedgeshaped sequences being thickest in the distal area and thinner on the crest of the High. The uppermost Finlayfjellet Beds (Tyrrellfjellet sequence 2) represents in contrast a uniform sequence. The Wordiekammen Formation is composed of 11 depositional carbonate facies and three overprint facies which are grouped into 10 facies associations. Each association represents a predictable pattern of facies, 0.5-22 m thick, which is repeated many times producing a distinct cyclicity in the succession. The Wordiekammen Formation is composed of 50 depositional cycles, 21 cycles in the Kapitol Member and 29 cycles in the Tyrrellfjellet Member. Analysis of the well-dated Tyrrellfjellet Member indicates that the succession was controlled by mixed 100 kyr and 400 kyr cyclicity signals which are believed to be a reflection of eustatic sea-level fluctuation and tectonic instability. Allocyclic control on the deposition dominated the majority of the Wordiekammen succession, and an abrupt change in depositional style in the uppermost Finlayfjellet Beds is believed to reflect the break-down of the Gondwanaland ice sheets and the end of glacio-eustaic control. Four key lithological intervals and unconformities have been correlated across the Billefjorden Fault Zone to the time-equivalent succession in Bünsow Land. Based on the correlation, it is considered that the distal part of the Nordfjorden High towards the west and the carbonate platform on Bünsow Land reflected a similar geological setting while the up-dip and crestal part of the Nordfjorden High was a positive feature that divided the two carbonate platforms during sea-level lows. Finally, it is believed that the Nordfjorden High remained a homoclinal carbonate ramp up to at least Late Asselian times.
