Be a bit more specific please.
Absurd. It's been 'preached' (actually 'known' is more precise) not for decades but for centuries. longer than evolution.
From Talk origins discussion of the geological column
My comments in bold
The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith. By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles. It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata. Studies done on the European continent soon demonstrated the universal validity of index fossils
decades before Darwin.
Note that evolution has nothing to do with how the index fossils are used to date strata! Any kind of object clearly restricted to a specific point in the geologic column would do just fine. If green dice were found only in the middle Ordovician strata, they would make excellent "index fossils."
Evolution should be seen as an explanation of the faunal succession....
Radiological methods give absolute ages, and these agree in ordering with those that had been previously established by creationists (ie pre-darwinian) scientists. (There is no way to know how many of these early geologists would have become evolutionists if they had been exposed to the theory).
It continues:
Creationists, on the other hand, must explain to us how sediment and rock laid down in a mere year can yield such fantastic, orderly differences in radiometric ages....
...And so on. Please read the cited site and explain where the logic is circular
