Direct trapped charge dating of Quaternary sediments and rock surfaces: testing a fundamentally new approach using infrared photoluminescence from feldspar Ghent University
Luminescence dating of quartz and K-feldspar is now widely used for establishing sediment deposition chronologies in a wide range of Quaternary research. The method is also increasingly applied in exposure and burial dating of rock surfaces. Recently, a fundamentally new signal from feldspar has been discovered: infrared photoluminescence (IRPL). IRPL directly taps the dosimetric information recorded by the minerals (the trapped electrons). ...
