How to solve radioactive dating problems
This is particularly important in light of the Biblical flood.
How a rock is formed is important to understanding its isotopic make-up and any dates derived.
For allegedly older samples K-Ar is used to "date" the standard and as such it still has the same problems as K-Ar dating.
Radioactive decay problems are solved by using a formula for exponential decay where the final amount of radioactive material equals the initial amount times e to the power of k times time.
Now in all fairness Ar-Ar dating can get the right age for a sample of known age, but it can also date samples as way too old, but without a known date there is no way of knowing when it is too old.One key factor is the fact that Ar-Ar dating needs a standard of "known" age.If the standard is of historically known age, such as would likely be used for testing Ar-Ar dating on sample of known age, then one would be more likely to get the correct age.However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock.Ages of Rocks in Millions of Years Sometimes different methods used on the same rock produce different ages.
If a sample shows only one-fourth of its estimated original quantity of , how old is it?
