Radiometric Dating Methods, Uses & the Snificance of Half-Life. The three main parameters that have to be set are the orinal amount of uranium and lead in the sample, the rate at which uranium and lead enter and leave the sample, and how much the rate of decay changes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.
Radiometric dating age of earth - Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock. Before 1955, ages for the Earth based on uranium/thorium/lead ratios were. the lead isotope ratios of certain meteorites in the Holmes-Houtermans equation.
Uranium-lead dating facts, information, pictures. The radiometric dater then uses the half-life of all four isotopes to find an age range the rock should be in. Uranium-lead dating All naturally occurring uranium contains 238U and 235U in the ratio 137.71. Both isotopes are the starting points for complex decay series.
