“…Ongoing development of ESR thermochronometry (Fang et al, 2018;Grün et al, 1999) may overcome the limitation of signal saturation. ESR signals saturate over timescales of up to~2 Myr (Rink, 1997), potentially extending the applicability of trapped charge thermochronometry methods to more environmental settings (e.g., Bartz et al, 2018) and longer timescales.…”

A transformative advance in Earth science is the development of low‐temperature thermochronometry to date Earth surface processes or quantify the thermal evolution of rocks through time. Grand challenges and new directions in low‐temperature thermochronometry involve pushing the boundaries of these techniques to decipher thermal histories operative over seconds to hundreds of millions of years, in recent or deep geologic time and from the perspective of atoms to mountain belts. Here we highlight innovation in bedrock and detrital fission track, (U–Th)/He, and trapped charge thermochronometry, as well as thermal history modeling that enable fresh perspectives on Earth science problems. These developments connect low‐temperature thermochronometry tools with new users across Earth science disciplines to enable transdisciplinary research. Method advances include radiation damage and crystal chemistry influences on fission track and (U–Th)/He systematics, atomistic calculations of He diffusion, measurement protocols and numerical modeling routines in trapped charge systematics, development of 4He/3He and new (U–Th)/He thermochronometers, and multimethod approaches. New applications leverage method developments and include quantifying landscape evolution at variable temporal scales, changes to Earth's surface in deep geologic time and connections to mantle processes, the spectrum of fault processes from paleoearthquakes to slow slip and fluid flow, and paleoclimate and past critical zone evolution. These research avenues have societal implications for modern climate change, groundwater flow paths, mineral resource and petroleum systems science, and earthquake hazards.

“…Due to the expected Early to Middle Pleistocene age of the fluvial terraces of the lower Moulouya it was challenging to establish luminescence chronologies. Quartz and K feldspar luminescence signals of the studied deposits had reached saturation, suggesting fluvial deposition at least as early as the Middle Pleistocene (Bartz et al, 2018;Fig. 2).…”

“…The ages range between Chronological correlation between the on-site archive (occupation phases of the rock shelter Ifri n'Ammar) and the off-site archives (ephemeral stream deposits of Wadi Selloum and fluvial terrace deposits of the lower Moulouya). Chronological data of the two fluvial systems are based on optically stimulated luminescence (OSL), thermoluminescence (TL) (see Bartz et al, 2015), thermally transferred OSL (TT OSL) (see Bartz et al, 2019), post-infrared infrared stimulated luminescence and electron spin resonance (ESR) dating (see Bartz et al, , 2018. From these results, phases of morphodynamic activity and stability can be deduced.…”

“…However, electron spin resonance (ESR) dating offered a useful alternative way to gain further chronological information. Based on the multiple-centre approach in fluvial environments (Duval et al, 2015), aluminium (Al) and titanium (Ti) centres were measured in quartz; this was cross-checked with palaeomagnetic analyses (Bartz et al, 2018). Thus, a robust geochronological framework was established for the fluvial terraces, with numerical ages dating back to the Early Pleistocene and ranging between ∼ 1.5 and ∼ 1.1 Ma (Bartz et al, 2018) (Fig.…”
