Non radiometric dating methods

In some cases these astronomical cycles in rock appear to have been laid down over some 25 million years (and radiometric dating puts the absolute age of the rock at some 200 million years).Dating Anomalies Here we outline a few dating methods or 'clocks' that present a dating anomaly when referenced to the widely accepted OE age of 4.6 billion years. At the outset we note C-14 cannot be used to directly date the earth for the simple reason that the unstable C-14 isotope has a half-life of just 5,730 years.One problem with earth dating is that the original earth surface is assumed to have eroded long ago.

More recently, work has been done on ocean sediments [S. This suggests that, given the current annual rates of erosion (some 27.5 billion tons), all earth's continents would be delivered into the oceans in just 14 million years.

These estimates give 4.4-4.5 billion years for moon rock, and 4.54 billion years for iron metreorites.

These techniques utilize the physical parameters of the earth, such as ice cores, annual lake sediments, and astronomical cycles.

Ice cores from Greenland and Antarctica show annual layers (varves) and can be traced up to about 40,000 years before the layers become too thin due to compaction.

Similarly, annual lake sediments can be used to estimate relative age and conventional interpretation for the Green River varves suggests they have been formed over some 20 million years.

This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.
