Terrestrial in situ cosmogenic nuclides: theory and application

  title={Terrestrial in situ cosmogenic nuclides: theory and application},
  author={J. Gosse and F. Phillips},
  journal={Quaternary Science Reviews},
The cosmogenic nuclide exposure history method is undergoing major developments in analytical, theoretical, and applied areas. The capability to routinely measure low concentrations of stable and radioactive cosmogenic nuclides has led to new methods for addressing long-standing geologic questions and has provided insights into rates and styles of surficial processes. The different physical and chemical properties of the six most widely used nuclides: 3He, 10Be, 14C, 21Ne, 26Al, and 36Cl, make… Expand

Cosmogenic dating of fluvial terraces, Fremont River, Utah
Absolute dating of river terraces can yield long-term incision rates, clarify the role of climate in setting times of aggradation and incision, and establish the rates of pedogenic processes. WhileExpand
Geomorphology and In-Situ Cosmogenic Isotopes
The answer, of course, is literally "blowing in the wind" for any geomorphologist with a dust-collecting network and infinite patience. But those results are not yet in, and if we wish to makeExpand
