Sedimentation experiments: Nature finally catches up!
Back in 1988 we published in this journal the English translation of a significant paper1 that was originally presented to the French Academy of Sciences in Paris on November 3, 1986 and then published in the Academy’s Proceedings.2 This was followed with our publication of a subsequent paper3 in 1990 that had also been initially presented to the French Academy of Sciences in Paris on February 8, 1988 and published in the Academy’s Proceedings.4
The author on both occasions was Guy Berthault, and his important experiments have demonstrated how multiple laminations form spontaneously during sedimentation of heterogranular mixtures of sediments in air, in still water, and in running water (see Figure 1). In subsequent research Berthault has teamed up with Professor Pièrre Julien in the Engineering Research Center of the Civil Engineering Department at Colorado State University, Fort Collins (USA). We published their results in 1994,5 after their research had been published by the Geological Society of France.6 Their sedimentation experiments are continuing.
The significance of this research has been repeatedly pointed out by creationist geologists. On June 12, 1980 a 25 foot (7.6 m) thick stratified pyroclastic layer accumulated within a few hours below the Mt St Helens volcano (Washington, USA) as a result of pyroclastic flow deposits amassed from ground-hugging, fluidised, turbulent slurries of volcanic debris which moved at high velocities off the flank of the volcano when an eruption plume collapsed (see Figure 2).7 Close examination of this layer revealed that it consisted of thin laminae of fine and coarse pumice ash, usually alternating, and sometimes cross-bedded. That such a laminated deposit could form catastrophically has been confirmed by Berthault’s sedimentation experiments and applied to a creationist understanding of the Flood-deposition of thinly laminated shale strata of the Grand Canyon sequence.8 Berthault’s experimental work and its implications have also been featured on videos.9,10
Now Nature has finally caught up! That is, the weekly international science journal Nature, arguably the world’s leading scientific publication, has just published and commented upon the results of experiments similar to those performed by Berthault,11,12 thus finally acknowledging what a creationist researcher has been demonstrating for more than ten years. However, not surprisingly, Berthault’s work is neither mentioned nor referenced in the Nature articles.
And what did the Nature authors discover? Makse et al. found that mixtures of grains of different sizes spontaneously segregate in the absence of external perturbations; that is, when such a mixture is simply poured onto a pile, the large grains are more likely to be found near the base, while the small grains are more likely near the top.13 Furthermore, when a granular mixture is poured between two vertical plates, the mixture spontaneously stratifies into alternating layers of small and large grains whenever the large grains have a larger angle of repose than the small grains. Application—the stratification is related to the occurrence of avalanches.
Fineberg agrees.14 Both the stratification and segregation of a mixture of two types of grains can be observed to occur spontaneously as the mixture is poured into a narrow box, the mixture flowing as the slope of the ‘sandpile’ formed steepens. When the angle of repose of the larger grains is greater than that of the smaller grains, the flow causes spontaneous stratification of the medium to occur, and alternating layers composed of large and small particles are formed, with the smaller and ‘smoother’ (lower angle of repose) grains found below the larger and ‘rougher’ grains (there was a beautiful colour photo in Nature). Even within the layers, size segregation of the grains occurs, with the smaller grains tending to be nearer the top of the pile.
We are naturally heartened by this ‘high-profile’ confirmation of Berthault’s experimental results, but readers of Nature could have read all about it more than a decade ago in the Creation Ex Nihilo Technical Journal. However, what this also confirms is that creation scientists do undertake original research, in this case, research on sedimentation that is applicable to the catastrophic processes of deposition during the Flood, contrary to the establishment’s uniformitarian (slow-and-gradual) interpretation of the formation of such sedimentary strata. And furthermore, creation scientists not only do original research applicable to Flood geology (even if Nature doesn’t recognise it), but the type of research they do is valid and good enough to be published in peer-reviewed secular scientific journals.
