Radiometric dating methods assume:

a) that no decay product was present initially, or that initial quantities
can be accurately estimated
b) that the decay system was closed through the years, and
c) that the decay rate was constant over time

What conditions could invalidate these assumptions?

In the article,"The Dating Gap" Marvin L. Lubenow writes:


*"It is impossible to give an evolutionary sequence to the human fossils
because *there is a coverage gap involving the dating methods which
evolutionists *believe are the most reliable radiocarbon and
potassium-argon (K-Ar). This gap *is from about 40,000 ya (years ago) to
about 200,000 ya on the evolutionist's *time scale. It covers roughly the
period known as the Middle Stone Age (MSA). *This coverage gap lies beyond
what is considered the effective range for *radiocarbon and prior to what
is considered the effective range for *potassium-argon. This problem period
may be even larger because: (1) some *dating authorities believe that the
effective range for K-Ar doesn't begin *until about 400,000 ya, and (2)
many of the older fossils are found at sites *that lack the volcanic rocks
necessary for K-Ar dating and hence cannot be *dated by this method at all.

*Although young-earth creationists challenge the legitimacy of all of the
dates *obtained by the long-term radiometric methods, even evolutionists
are beginning *to admit that this dating gap presents a problem for them.
However, the real *seriousness of this problem seems to elude them, even
when they occasionally *refer to it in their writings.[1]
