Cosmogenic nuclide dating ppt

Applications in Hungary The Danube, the major river of the Pannonian Basin system, is the only river cutting through the NE-SW Transdanubian Range (TR).

Those rocks and sediments are suitable for burial dating which once were exposed to cosmic irradiation, but have been buried since then.Radioactive nuclides reach their secular equilibrium after 3-4 half-lives, which defines the applicability range of the method.See more about the method in: Gosse and Phillips (2001); Dunai (2010); Granger et al. Exposure age determination Exposure age of a rock is the time elapsed since it has been exposed to cosmic irradiation.Cosmogenic nuclide dating uses the interactions between cosmic rays and nuclides in glacially transported boulders or glacially eroded bedrock to provide age estimates for rock at the Earth’s surface.It is an excellent way of directly dating glaciated regions.

During 2014-2015, partial treatment of a sample sets (crushing, sieving, quartz purification and etching) occurred in our lab and the extraction chemistry of the cosmogenic nuclides occurred at the CEREGE LN2C (Aix en Provence, France), the location of the accelerator mass spectrometry (AMS) measurements (Ruszkiczay-Rüdiger et al., 2016b).
