How old is the earth based on radiometric dating dating slang vanilla
Radiometric dating of granitic intrusions associated with the Caledonian orogeny yields ages between about 430 million and 380 million years.The igneous activity that produced such intrusions...There is no absolutely reliable long-term radiological 'clock'." "The age of our globe is presently thought to be some 4.5 billion years, based on radio-decay rates of uranium and thorium.Such ‘confirmation’ may be shortlived, as nature is not to be discovered quite so easily.Two of the most widely-known systems are the potassium-argon method and the uranium-lead method.
Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.
It disintegrates at a measured rate into calcium and argon.
Similarly, the radioactive element uranium decomposes into lead and some other elements.
Age estimates which are obviously wrong or contradictory are sometimes produced.
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 speed of the disintegration process is measured.
