The third cycle, which was about 50 years long, agrees with no well-established rhythm. Steve Austin wrote: "Thin, rhythmic silt and clay layers found in lakes are frequently called 'varves,' with each layer being considered to represent annual repetitions of a slow sedimentary process.
Observations of modern glaciers and recent climate simulations show that the ice sheets during the Ice Age melted rapidly, much faster than indicated by varves.
A further investigation of varves demonstrates that other mechanisms deposit varve-like couplets in a short time. A method to distinguish between annual depositional sequences and other mechanisms is difficult to apply.
Richard Foster Flint, in his famous textbook, Glacial and Pleistocene Geology, describes more modern varves ("rhythmites") that have been studied in Switzerland: Rhythmites deposited in a lake near Interlaken in Switzerland are thin couplets, each consisting of a light-colored layer rich in calcium carbonate and a dark layer rich in organic matter.
Proof that these rhythmites are annual and are therefore varves is established on organic evidence.
Then the curves or such parts of them as included undisturbed varves of normal variation and thickness were selected for constructing the normal curve, and those curves were discarded that showed great difference in thickness from the majority or poor agreement in the shape of the curve.
Varves have been used to set up the first "absolute" chronology, which significantly exceeds the Scriptural time scale from Genesis.
Thus, varve chronology is not scientifically sound.
PREDICTION 10: Corings taken anywhere in the bottom of any large lake will not show laminations as thin, parallel, and extensive as the varves of the 42,000-square-mile Green River Formation, perhaps the world’s best known varve region.
Similar laminated carbonates and evaporites occur in Alberta.
