This provides an ideal method for determining when a glacier retreated from a region, hence exposing the ground beneath.
Technological developments in the last few decades have allowed more precise measurements of their concentration in terrestrial rock samples and this dating technique is becoming increasingly popular.
Towards a better understanding of Beryillium-10 and Beryllium-9 dynamics in river sediments.
R., Trodick, C., Dejong, B., Greene, S., and Pavich, M. Background rates of erosion and sediment generation in the Potomac River basin, USA, derived using in situ ¹⁰Be, meteoric ¹⁰Be, and ⁹Be GSA Bulletin.
In the future we hope to prepare targets for protein-specific Cosmogenic nuclides are used to determine exposure ages and erosion rates of landforms and sediments, and exhumation rates of catchment basins.
Production rates of these radioisotopes in minerals exposed to cosmic rays are very low (i.e.I collected the samples in the field in 20: Having collected the samples in the field and received funding to run them, I went up to the Scottish Universities Environmental Reserach Centre (SUERC) laboratories in East Kilbride to start the process!As 10-Beryllium and 26-Aluminium preferentially build up in quartz, the aim of the first week was to crush down the samples and extract as pure quartz as we could.Atmospheric atomic bomb testing in the 1950's and 60's bolstered the concentration of tritium in the atmosphere where it can become incorporated into a water molecule and enter the water cycle.During precipitation events this tritiated water enters groundwater and can be used as a dating tool for recharge.For C we are still in development mode, so it is not possible to estimate the quene time.
