Uranium dating is used for
A speck of radioactive element such as Uranium, for example, will leave a sphere of discoloration of characteristically different radius for each element it produces in its decay chain to lead Decaying radioactive particles in solid rock cause spherical zones of damage to the surrounding crystal structure.
Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium-234 (234 U) and uranium-238 (238 U).
Since the flood was accompanied by much volcanism see Noah's Flood… , How did animals get from the Ark to isolated places? The lead and helium results suggest that rates of radioactive decay may have been much higher in the recent past. Therefore, one can assume that the entire lead content of the zircon is radiogenic , i. We are a research and service division of: Total 14 C is also proportionately lowered at this time, but whereas no terrestrial process generates any more 12 C, 14 C is continually being produced, and at a rate which does not depend on carbon levels it comes from nitrogen.

How Old is that Rock?
It is very much driven by the existing long-age world view that pervades academia today. So, we start out with two isotopes of uranium that are unstable and radioactive.

The isotope 14 C, a radioactive form of carbon, is produced in the upper atmosphere by neutrons striking 14 N nuclei.

Uranium—uranium dating , method of age determination that makes use of the radioactive decay of uranium to uranium; the method can be used for dating of sediments from either a marine or a playa lake environment. It is the principle fuel for nuclear reactors, but it also used in the manufacture of nuclear weapons.

A stronger magnetic field deflects more cosmic rays away from the Earth. The secular scientific literature lists many examples of excess argon causing dates of millions of years in rocks of known historical age.

For example, potassium decays to argon; uranium decays to lead via other elements like radium; uranium decays to lead; rubidium decays to strontium; etc.
