This illustrates the whole problem with the radioactive dating of geological events.. The same applies with all other overlapping isotope dating methods,.

It is usually a highly purified form of a low-abundance natural isotope, but an even better spike is an isotope with a mass not found in. Many material remains of mans past have no dating problem they may be, like coins, or most coins, self-dating, or they may Radioisotope Dating. Problems. Review Questions. Contributors. Atoms that have the same atomic number (number of protons), but different mass numbers (number of protons and neutrons) are called isotopes. Problems with the U-Pb Radioisotope Dating Methods1. Ironically it is the slow decay rates of isotopes such as 87Rb, 176Lu, 187Re, and 147Sm used for deep time dating that makes precise measurements of their decay rates so difficult.
