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.

(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.All the canyon layers are ocean bottom sediments, filled with fossils of ocean-dwelling creatures and plants almost a mile high from top to bottom.The Cardenas Basalt bottom layer (below the Cambrian explosion) is usually dated with Rhobidium -Strontium and calculated to be about 1 billion years old.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.Radioisotope dating, using the trace amounts of radioactive elements within the rock, was quickly accepted as proof the earth is millions and millions of years old. The Radioactive elements decay from heavier larger atomic elements (parent) into smaller atomic elements (daughter) that are more stable. The rate of decay and the amount of parent / daughter elements present today in a rock sample is used to calculate back to the estimated age of when the rock was first formed.

That concept began with eighteenth-century French naturalist Georges Cuvier, picked up steam with Charles Lyell, and it has been in vogue ever since.
