In situ-produced cosmogenic krypton in zircon and its potential for Earth surface applications
Abstract. Analysis of cosmogenic nuclides produced in surface rocks and sediments is a
valuable tool for assessing the rates of processes and the timing of events that
shaped the Earth surface. The various nuclides that are used have specific
advantages and limitations that depend on the time range over which they are
useful, the type of material they are produced in and not least the
feasibility of the analytical effort. Anticipating novel applications in
Earth surface sciences, we develop in situ-produced terrestrial cosmogenic
krypton (Krit) as a new tool, the motivation being the availability of
six stable and one radioactive isotope (81Kr, half-life 229 kyr) and of
an extremely weathering-resistant target mineral (zircon). We provide proof
of principle that terrestrial Krit can be quantified and used to
unravel Earth surface processes.
