Radiometric Dating _____ (print name) We can determine e age of e Ear by using e ay of radioactive elements or isotopes. e elements most frequently used are Uranium 238 and Lead 206 (from e mineral Zircon). Potassium 40 and Argon 40 (from e Mica minerals). Rubidium 87 and Strontium 87 (from Feldspar minerals). Uranium-Series Dating. Radiometric dating me ods were developed in e twentie century, and have revolutionized Quaternary Science. In 1902, physicists Ernest Ru erford and Frederick Soddy had discovered at radioactive elements broke down into o er elements in a definite sequence or series, rough e process of nuclear fission. (Accurate Radiometric Dating can only be obtained if e mineral remained in a closed system during e entire period since it's formation.) Radiocarbon Dating. Me od, using carbon-14, for determining age by comparing amounts of carbon-14 to carbon-12 in a sample. It is used for dating once living material.
