Radiactive dating

Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.A popular and supposedly foolproof method was used on two lava flows in the Grand Canyon that should be ideal for radioactive age estimation. Young basalt rock at the Canyon's top produced an age estimate 270 million years older than ancient basalt rock at the Canyon's bottom.The problem seems to arise from basic wrong assumptions in the method (rubidium-strontium isochron).The Carbon-14 age estimating method is, at best, only useful for estimating the age of things that are thousands of years old, not millions or billions.And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.Theoretically, Creationism remains workable within a wide range of age estimates.

Two of the most widely-known systems are the potassium-argon method and the uranium-lead method.Similarly, the radioactive element uranium decomposes into lead and some other elements.How are these processes used to estimate the age of rocks?What are some of the assumptions made by most Evolutionists in using these systems?"It is obvious that radiometric techniques may not be the absolute dating methods that they are claimed to be.
