Further thick sediment layers were soon deposited on top of them.

The position of the Cardenas Basalt lava flows in the overall succession of rock layers in Grand Canyon can be seen in the generalized geologic “block” diagram of Grand Canyon .

These are often characterised as the norm, rather than the exception.

I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.

A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

Unlike people, you can’t really guess the age of a rock from looking at it.

Yet, you’ve heard the news: Earth is 4.6 billion years old. That corn cob found in an ancient Native American fire pit is 1,000 years old. Geologic age dating—assigning an age to materials—is an entire discipline of its own.

For decades, the biologists have boldly proclaimed that, whereas we cannot observe today one type of creature evolving into a totally different type of creature, “Time is the hero of the plot. No one even bothers to ask what assumptions drive the conclusions.

So let’s take a closer look at these methods and see how reliable they really are.
