Cosmogenic Isotope Dating

Landscape reconstruction using cosmogenic isotope dating

Cosmogenic in-situ produced terrestrial radionuclides 10Be, 26Al and 36Cl are now used extensively for determining the exposure history of bedrock surfaces, glacially transported boulders, sedimentary deposits, fans, buried cave sands, dune and river sands and fault scarps to determine glacial chronologies, basin wide erosion rates, burial ages, fault and slip rates, landscape change in paleo-geomorphology and climate change.

Cosmogenic isotope dating and tracing can be performed on quartz bearing rocks, granites, carbonates, sediments and ice. The correct capability to utilise depends on the sample type and the isotope(s) of interest.
