A further example from a lava flow off the coast of hawaii shows similar discrepancies if dated with the carbon14 method the flow appears to be less than 17000 years old but dating with the potassium argon method gives dates of 160000 to 43 million years.
carbon dating learn about carbon dating and how it is used to estimate the age of carbonbearing materials between 58000 to 62000 years.
carbon dating gets a reset climate records from a japanese lake are providing a more accurate timeline for dating objects as far back as 50000 years.
carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
How accurate is radiocarbon dating radiocarbon ages less than 3500 years old are probably accurate however before accepting any radiocarbon date one should know how the technique works its limitations and its assumptions.
Another absolute dating method is thermoluminescence which dates the last time an item was heated it is the only method that can be used to date rocks pottery and minerals for dates that are approximately between 300 to 10000 years old.
radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon in which trace radioactive impurities were selectively incorporated when they were formed the method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products which form at a known constant rate of decay.

The following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methodscarbon 14 is used for this example which was put out by dr hovind dr hovind r1 the atmospheric c14 is presently only 13 of the way to an equilibrium value which will be reached in 30000 years this nullifies the carbon14 method as well as demonstrating.
