This method is used only on metamorphic and igneous rocks – not sedimentary rocks (which are rocks laid down by water – and is where the fossils are primarily found).The radio-dating calculations are based on a series of Assumptions: 1) The decay rate has not changed.Actually the assignment of a certain number of millions of years to a rock formation does not derive from the strata itself.The standard Geological Column became the reference point, even though it does not appear anywhere on earth except in text books.Then they ALWAYS come back dated at 100,000s to millions of years old. NEVER do they come back from the lab, with the note: Too young to measure. If you know the date of the source of the rock, they say you don’t have to accept this dating technique’s numbers… But recently, the RATE research team has conclusively demonstrated (with independent lines of evidence) that radioactive decay rates, widely used to bolster deep time, were dramatically accelerated in the past.but if its an unknown sample, then they say: “Oh, you can trust the lab dates! You see, the radiometric dating technique’s do not work when you can check the dates, but you should trust them when you can’t check them. RATE found 3 indicators that strongly indicate decay rates changed in the past, all pointing to a young age for the rocks and the earth.Much later after the Grand canyon was already formed, igneous rocks were formed from a volcano on top of the canyon, that Indians saw erupt, only about 1000 years ago.(The volcano lava flows have Indian artifacts in them, and go over the canyon walls.) These rocks were dated using the same method in the lab and were assigned an age of 1.3 billion years old.
However, research by geologist John Woodmorappe (a pen name) revealed that the radiometric methods used today were actually hand-picked to coincide with the dates previously assumed for the geologic column diagrams.
This is a real and common problem with radiometric dating techniques.
Consider also: ALL of the samples taken from volcanic eruptions of known times and dates are carefully collected and sent to the labs. It is the prime reason many scientists have had doubts about radiometric dating all along.
That concept began with eighteenth-century French naturalist Georges Cuvier, picked up steam with Charles Lyell, and it has been in vogue ever since.
This is despite the fact that it causes more problems for interpreting rock strata than it solves.

These dating methods rely on a series of assumptions about the amounts of the parent-daughter elements, and a constant rate of decay. It has been accepted that a rock is formed when it first cools down from a molten or semi-molten state, which may include a variety of elements, including radioactive ones. For the last 100 years we have been able to measure the decay rate, and during this time it has been very steady, very consistent.
