In fact, he would have been equally happy with any date a bit less than 200 million years or a bit more than 30 million years.They would all have fitted nicely into the field relationships that he had observed and his interpretation of them.Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.These were then eroded and Sedimentary Rocks B were deposited.In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.Creationists would generally agree with the above methods and use them in their geological work.And then, depending on the assumptions we make, we can obtain any date we like.
However, this error is not the real error on the date.
it matches what they already believe on other grounds. A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.
The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.
We can crush the rock and measure its chemical composition and the radioactive elements it contains.
But we do not have an instrument that directly measures age.
The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.
