Radiocarbon dating vs ams

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.

For instance, the Institute for Creation Research has on display multiple examples of fossils from the Green River Formation. 2a) contains the fossilized fish Diplomystus dentatus and Knightia eocaena.

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.

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).

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.
