Can radiometric dating be used on sedimentary rocks victoria bc dating sites
For some other materials, the event is the end of a metamorphic heating event in which the rock gets baked underground at generally over radioactive dating igneous rocks thousand degrees Fahrenheitthe uncovering of a surface by the scraping action of a glacier, the chipping of a meteorite off of an asteroid, or the length of time a plant or animal has been dead.
Today the Earth is known to be approximately 4.5 billion years old.
According to theory, electron-capture is the most likely type of decay to show changes with pressure or chemical combination, and this should be most pronounced for very light elements.
This would probably have a larger effect lower down, where the pressure of argon would be higher.
The only correlation I know about that has been studied is between K-Ar and Rb-Sr dating on precambrian rock.
Let us consider again the claim that radiometric dates for a given geologic period agree with each other.
Though Hutton believed in uniformitarianism, the idea was not widely accepted at the time.
