Summary

While recognition and measurement of strain markers in active tectonic settings have improved over the past half century, our capacity to establish rates and timing of neotectonic processes lagged due to difficulties in dating the deformed landforms. The development and refinement of geochronology strategies based on the interpretation of terrestrial in situ produced cosmogenic nuclides (TCN) have provided a means to directly date fault surfaces and estimate rupture frequency, date or bracket the timing of deformation events, and demonstrate more clearly than ever the relationships between sediment fluxes and tectonic processes. With an effective range of decades to 107 years, theTCNmethod bridges the gap between geodetic time scales and chronologies of longer time scale processes associated with orogen-scale crustal dynamics. This chapter provides a summary of current TCN approaches for assessing the erosion and exposure history of surfaces and sediments in tectonically active regions.
