Aarhus Cosmogenic Nuclides Group apply cosmogenic nuclides to quantify rates of geomorphic processes in cold, mountainous, and desert regions of the world—with an aim to understand how climate and tectonics drive the evolution of landscapes over thousands to millions of years.
We specialise in pairing cosmogenic nuclide analysis with computational modelling to resolve questions related to:
Field sites include Scandinavia, Greenland, Svalbard, Nepalese Himalaya, arid central Australia, and Egypt's Eastern Desert.
Our laboratory has the capacity for full preparation of samples for cosmogenic nuclide measurement plus a wide range of sedimentological and geochemical analyses. Our computational toolbox includes purpose-built landscape evolution models and Markov-Chain Monte Carlo algorithms.
We work closely with the director of the AMS facility, Jesper Olsen, in the Department of Physics and Astronomy at Aarhus University.
