He did not need to wait long. They are mathematically clever, and we may explore them in a future article. The time at which a given potassium atom converts to argon atom cannot be predicted in advance. But age is not a physical property. While uranium is water-soluble, thorium and protactinium are not, and so they are selectively precipitated into ocean-floor sediments , from which their ratios are measured. In this type of method, we have good theoretical reasons to assume at least one of the initial conditions of the rock. If the dating methods are all objective and reliable, then they should give similar dates. Ernest Rutherford and Frederick Soddy jointly had continued their work on radioactive materials and concluded that radioactivity was due to a spontaneous transmutation of atomic elements. But we must still make an assumption about the rate at which dust accumulated in the past. This scheme has application over a wide range of geologic dates.

    Carbon dating is not used on rocks, because rocks do not have much carbon in them.

    And since helium is a gas, it can leak through the rocks and will eventually escape into the atmosphere.

    In fact, they constitute an essential part in any precise isotopic, or absolute, dating program. This involves inspection of a polished slice of a material to determine the density of "track" markings left in it by the spontaneous fission of uranium impurities.
