1997), although Nature did not acknowledge Berthault’s prior work (Snelling 1997).
Furthermore, these experimental results have been confirmed by field observations. Helens subsequent to the well-known May 18, 1980, eruption resulted in the formation of a 762 cm (25 feet) thick deposit consisting of many thin, alternating fine-grained and coarse-grained laminae very similar to varves.
This deposit formed within just a few hours (Morris and Austin 2009, 50, 52–54). “A Novel Approach to Varve Counting Using μXRF and X-Radiography in Combination with Thin-Section Microscopy, Applied to the Late Glacial Chronology from Lake Suigetsu, Japan.” Quaternary Geochronology 13: 70–80.
Likewise, interpretation of other rock units consisting of many thin laminations makes more sense if one assumes that the laminae were formed rapidly.
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.
Their article claims that the very large number of Lake Suigetsu varve counts is strong evidence for an old earth.
Creation scientists would argue that most of the lamination couplets are not true annual events.
Davidson and Wolgemuth, however, present a new “spin” on the argument: they claim that the correlation between these “varve” counts and radiocarbon dates (as well as tree-ring counts), proves that the Lake Suigetsu varves are true annual events, thus presenting an unanswerable argument for an old earth. Furthermore, they seem to misunderstand the recent results of the RATE research project that showed strong evidence of ubiquitous in situ radiocarbon within fossil specimens that should be radiocarbon “dead” by uniformitarian reckoning. Such results pose a serious challenge to uniformitarian assumptions underlying conventional radiocarbon age-dating methods. 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).
