We are very pleased to announce the next Landscapes Live online seminar by Nathan Brown (University of Texas, Arlington) this Thursday, November 3rd at 16:00 CET (Amsterdam/Berlin/Paris).
Abstract: Luminescence dating is commonly used to constrain when sediment was last exposed to sunlight. For mineral grains within the dark interior of a rock outcrop, however, the luminescence signals relate to thermal exposure. For example, with grains kept at a constant temperature for time periods longer than several hundred thousand years, luminescence signals can be used to estimate that storage temperature over a wide range, from upper-crustal through atmospheric temperatures (paleothermometry). Conversely, grains which have changed temperature recently can embed information about their time-temperature history (thermochronology). In this presentation, I will review the basic principles underlying luminescence thermochronology, some example applications, and future research directions, with emphasis on understanding surficial processes. Advantages of this technique include the ubiquity of target minerals (primarily K-feldspar), its sensitivity to low temperatures and recent time periods, as well as the diversity of luminescence signals which can be measured from a single sample to gain additional information of a sample's geothermal history.
The seminar will be live on Zoom and open to anyone interested (limit of 300 participants). Register in advance for this meeting: https://ucmerced.zoom.us/meeting/register/tZMrfu2uqjkoGt3s5__RNRLV95G-HG2emSHM
