Uranium lead dating method

By then, the relative ages (order) of the geologic column had already been worked out in some detail.

Radiometric dating would later confirm the relative ages of the strata and tie them to absolute dates.

Your chances are 6.2 billion to one of getting the right order for all thirteen.

If most of the geologic column were created during Noah's flood, would it really matter whether a zircon crystal was found in Cambrian strata or Cretaceous strata, in Jurassic strata or Tertiary strata?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.(Far from being a rubber stamp, radiometric dating would go on to revolutionize our understanding of the Precambrian.) Thus, it became possible to date strata directly from index fossils.Note that evolution has nothing to do with how the index fossils are used to date strata!
