Industrial revolution radiocarbon dating
"[d] Deep ocean deposits supposed to contain remains of most primitive life forms are dated within 40,000 years. "[b] Only three of the 15,000 reported ages are listed as `infinite.' "[c] Some samples of coal, oil, and natural gas, all supposedly many millions of years old have radiocarbon ages of less than 50,000 years.If reading that article on its own you think that section needs more explanation, I might try too add some.The Hallstatt plateau is just one of many, but it is an especially prominent and well known one.
But subsequent investigations have revealed it to be wholly inadequate for accurate dating of ancient materials. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts. This is because, with a half-life of only 5,730 years, initial radiocarbon in a fossil decreases in about ten half-lives to a level too low to be measured."—Robert E.
Since then atmospheric observations show the levels have been dropping, and are now close to the pre-industrial proportions.
The scientists seem unaware of carbon-14 reported from coal (9/25/03), diamonds, and dinosaur bones (see 6/18/15).
Second, it is assumed that within any given sample, no parent or daughter elements ever entered or left the sample.
Third, the rate of radioactive decay has remained constant.
