The history of Earth in the Solar System has been unraveled using natural radioactivity. The sources of this radioactivity are the original creation of the elements and the subsequent bombardment of objects, including Earth, in the Solar System by cosmic rays. Both radioactive and radiogenic nuclides are harnessed to arrive at ages of various events and processes on Earth. This collection of chapters from the Treatise on Geochemistry displays the range of radioactive geochronometric studies that have been addressed by researchers in various fields of Earth science. These range from the age of Earth and the Solar System to the dating of the history of Earth that assists us in defining the major events in Earth history. In addition, the use of radioactive geochronometry in describing rates of Earth surface processes, including the climate history recorded in ocean sediments and the patterns of circulation of the fluid Earth, has extended the range of utility of radioactive isotopes as chronometric and tracer tools.

After the discovery that elements were commonly composed of isotopes, there developed a range of studies of the variability of isotopic compositions in Earth materials, which was able to add to our understanding of Earth processes and history. This collection of chapters from the Treatise on Geochemistry describes the range of isotopic studies. The chapters are grouped into the following categories: light stable isotopes, radiogenic tracers, noble gases and radioactive tracers. The first three groups depend on mass spectrometric measurements. The section on radioactive tracers employs both radioactive counting techniques and the newly developed accelerator mass spectrometric techniques.

Excerpt from Keplers Traum vom Mond Was wirst Du sagen, wenn ich Dir zur Erheiterung meine 'astro nomie des Mondes, oder der Himmelsersoheinungen auf dem Monde' zueignete? Verjagt man uns von der Erde, so wird mein Buch als Führer den Auswanderern und Pilgern zum Monde nützlich sein. Dieser Schrift gebe ich Plutarchs, Mondgesicht' bei, von mir neu übersetzt und in den meisten lückenhaften Stellen nach dem Sinn ergänzt, was dem Kylander, der kein Astronom war, nicht ge lingen konnte. Das ist Alles, was wir in K oglers Schriften über das 'samnium' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
