Short summary
This study demonstrates the utility of laser-ablation-based detrital biotite Rb–Sr geochronology to investigate the rates of exhumation and burial in active mountain-building systems. It is further demonstrated that additional chemical data collected during spot analyses can be used to determine temperatures recorded in biotite. The method used has advantages over traditional methods in speed, ease of acquisition, and the ability to collect additional chemical information.
