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.
U dates of R33 and 500 Ma solution are 419.88 ± 0.94 Ma (n = 7; MSWD = 6.8) and 500.50 ± 0.19 Ma (n = 9; MSWD = 0.84), respectively.
These results demonstrate that the CA-ID-TIMS procedure is well established at GIGCAS.
Because varves are by definition “annual,” they have been used to measure the ages of lake deposits and as proof of ages of millions of years.
Likewise, interpretation of other rock units consisting of many thin laminations makes more sense if one assumes that the laminae were formed rapidly.
Geologists have known for quite some time that multiple laminae may form very rapidly.
French creation scientist Guy Berthault performed groundbreaking laboratory experiments demonstrating that multiple laminations can form spontaneously when sediment mixtures consisting of particles of different sizes are deposited in air, running water, or still water.
For instance, the sediments of the Green River Formation in Wyoming are thought to represent many million years of continuous deposition (Bradley 1929a, b).
Yet bat, bird, fish, plant and many other fossils within the Green River Formation strongly suggest rapid, rather than slow and gradual, deposition of these fine laminae (Grande 1984).
