“…5), as evidenced by a decrease in U concentrations and increased Th/U and Sm/U ratios. This is the same temperature range as was observed for goethite and hematite in previous studies (Vasconcelos et al, J o u r n a l P r e -p r o o f 2013; Danišík et al, 2013;Reiners et al, 2014). Hematite samples showed a more consistent U-loss temperature than goethite samples.…”

“…Several studies have lowered extraction temperatures for both goethite and hematite to 500-850°C because U volatilization was observed at temperatures above 1000°C (Danišík et al, 2013;Reiners et al, 2014;Garcia et al, 2018;Wells et al, 2019). For very fine-grained hematite samples, which likely have low helium-retentivity, these temperatures might be sufficient to completely extract helium.…”

“…The Th/U ratio is frequently used as a criterion to assess possible U-loss in iron-oxides (e.g. Danišík et al, 2013;Vasconcelos et al, 2013;Evenson et al, 2014;Ault et al, 2015;Calzolari et al, 2018;Garcia et al, 2018).…”

“…This compilation highlights the longevity of continental landscapes and protracted laterite formation during multiple weathering episodes. In addition, supergene hematite or goethite formation can also be used to date paleochannel evolution and water table drawdown during climate (e.g., Danišík et al, ; Heim et al, ) or landscape (Monteiro, Vasconcelos, & Farley, ; Riffel et al, ) changes.…”

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.
