| Abstract
|
:
|
The large increase in the knowledge of nuclear physics and radiochemistry occasioned by the Manhattan Project during World War II has had important ramifications in most other fields of experimental science. Not only did the Project produce many new ideas and techniques, but also numerous young scientists who were interested in the application of these techniques to other areas of study. In earth science, geochemistry and nuclear geophysics have been profoundly affected by these developments. This is particularly true of the general area of age determination of rocks and minerals. More research in quantitative geochronometry has been conducted during the past decade than in the previous five years. In this chapter an attempt is made to review the status of the significant isotopic clocks. There has been no attempt to cover the literature exhaustively. The discussion is be concerned primarily with the developments of the past decade ending with the summer of 1954. This chapter starts with the discussion of the “lead methods” used to designate the age measurement. The other methods that have been discussed in this chapter are: the carbon-14 method, the strontium method, the potassium methods, the helium method, and the ionium method.
