This review article focuses in particular on their claim that the good correlation between “varve” counts in Japan’s Lake Suigetsu (Fig.
1) and the radiocarbon ages for plant fossils found within the lake’s sediments present an unanswerable argument for an old earth.
Likewise, on November 12, 2012, the author of the Naturalis Historia blog posted a lengthy article on Lake Suigetsu (https://thenaturalhistorian.com/creationism/) which included a reproduction of Figure 7 from the Davidson and Wolgemuth (2010) paper. Alternating patterns of distinct laminae are commonly identified within glacial lake deposits and are generally interpreted in the following way: during the summer months as meltwaters increase flow to the lakes, layers of more coarse sediment are formed, whereas the decreased meltwater in winter results in thinner, more clay-rich layers.
A varve is defined as “A sedimentary bed or sequence of laminae deposited in a body of still water within one year’s time . The net result, in theory, is an “annual” varve consisting of a summer and winter depositional couplet layer.
However, careful examination of the papers they cite shows that this apparent agreement is the result of the typical uniformitarian circular reasoning.
Furthermore, Davidson and Wolgemuth made numerous errors in their article (even within their own uniformitarian framework) which cause one to question whether they carefully read all of the technical papers they cited.
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). The Bio Logos Foundation has published a popular-level article by old-earth geologists Gregg Davidson and Ken Wolgemuth presenting arguments for an old earth. One such argument involves counts of sedimentary laminations (“varves”) within the floor of Japan’s Lake Suigetsu. “SG06, A Fully Continuous and Varved Sediment Core from Lake Suigetsu, Japan: Stratigraphy and Potential for Improving the Radiocarbon Calibration Model and Understanding of Late Quaternary Climate Changes.” Quaternary Science Reviews 36: 164–176. 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.
