Attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth. A recent article about U-series dating of Paleolithic art in 11 caves in Spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting questions about the scientifically accepted age of the Earth. Although Paleolithic art has nothing to do with evolution, the article does give us an opportunity to talk about dating techniques in general, and U-series dating in particular. Furthermore, the measured levels of uranium isotopes are nowhere near what the Old Earth model predicts. All dating methods depend upon measurement of something that varies with time.
How are C and U dating used together in order to determine fossil ages? | Socratic
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. Because this method is useful for the period of time from about , years to 1,, years before the present, it helps in bridging the gap between the carbon dating method and the potassium-argon dating method.

Uranium—uranium dating is a radiometric dating technique which compares two isotopes of uranium U in a sample: uranium U and uranium U. It is one of several radiometric dating techniques exploiting the uranium radioactive decay series , in which U undergoes 14 alpha and beta decay events on the way to the stable isotope Pb. Other dating techniques using this decay series include uranium—thorium dating and uranium—lead dating. This decays with a half-life of 6. This isotope has a half-life of about , years.
