Two of the main methods used to justify an old earth are radiometric dating, which will be the subject of a future blog and ice core dating, which we will discuss here.
These layers are presumed to be the result of annual fluxuations in climate, and using this method, uniformitarians purport ages of over 100,000 years.
Creationists, such as Michael Oard, contend that these laminations are from subannual events, including layering due to dust to be found in a post-flood ice age.
It cannot be applied to prove what has happened in the past because it is not possible to go back into the past.
Second, the evolution story requires very long ages to give it any credibility.
The layers in the cross-section of ice are then counted.
The proposed method yields new dating scenarios simultaneously for several cores by making a compromise between the chronological information brought by glaciological modeling (i.e., ice flow model, firn densification model, accumulation rate model), and by gas and ice stratigraphic constraints.
This method enables us to gather widespread chronological information and to use regional or global markers (i.e., methane, volcanic sulfate, Beryllium-10, tephra layers, etc.) to link the core chronologies stratigraphically.
2006) and to 1642±5 BC by identifying a volcanic fallout layer in the Greenland ice cores (Vinther et al. However, archaeologists have estimated the eruption almost a century later than the other datings.
The disagreement between the datings has caused a debate about the reliability of the different dating methods, with archaeologists questioning the radiocarbon and ice core datings as they do not agree within 2σ errors.Each layer of snow is different in chemistry and texture, summer snow differing from winter snow.
