However, recent research by Schieber, Southard and Thaisen (2007) and Schieber and Yawar (2009), using the Indiana University Flume Laboratory, has demonstrated that the commonly observed laminated mudrocks, so prevalent throughout the rock record and around the globe, formed by moving water, and energetic deposition. Their experiments showed that mudrocks, and laminae in particular, form not by slow deposition out of a stagnant water column, but by flowing water at speeds of 0.3 m/sec (1 ft/sec). Even uniformitarian geologists have acknowledged that stratification can occur quickly. Almost ten years later, the results of similar experiments were published in Nature (Makse et al. There are some varve pairs that form in a single year, but in many cases, the observational evidence shows that multiple supposed varve couplets can and have formed in a single year (Buchheim and Biaggi 1988; Lambert and Hsü 1979; Makse et al. In fact, it has been documented that at least five pairs of varve couplets can form in a single year due to fluctuations in water flow (Lambert and Hsü 1979). It appears then, that claiming a varve is an annual event is an assumption in itself; one steeped in uniformitarian thought, but not reality. “Improved C Dating of a Tephra Layer (AT Tephra, Japan) Using AMS on Selected Organic Fractions.” Nuclear Instruments and Methods in Physics Research B (223–224): 555–559. In the past, uniformitarian philosophy taught that clay-rich mudrocks formed by slow settling out of nearly stagnant water. It also held that thick deposits of clay-rich rocks needed thousands and even millions of years of slow, stagnant clay deposition, as is observed in parts of the deep ocean today. “Spontaneous Stratification in Granular Mixtures.” Nature 386 (6623): 379–382.
Creation scientists would argue that most of the lamination couplets are not true annual events.
They made the same claims with the same example in a subsequent, virtually identical, presentation in a widely circulated Christian journal (Davidson and Wolgemuth 2012).
Other old-earth advocates (Morton 2003) also believe this to be a strong argument.
This occurs because particles of different sizes have a tendency to spontaneously segregate and stratify themselves.
Berthault’s research was published in two papers published by the French Academy of Sciences (Berthault 1986, 1988a), and English translations of these papers were subsequently published in a prominent creation research journal (Berthault 1988b, 1990).
