Arizona Radiogenic Helium Dating Laboratory
ARHDL

(U-Th)/He geochronology & thermochronology applied to Earth and planetary science
Founded November 2006

Decay of uranium and thorium to helium provides a versatile chronometer for examining the timing and rates of a wide variety of events and processes in earth and planetary science. (U-Th)/He dating is often used to constrain thermal histories of rocks and the timing and rate of orogenic events and the topographic evolution. Using (U-Th)/He thermochronology in this way we work with a wide range of geomorphologists and tectonicists to address problems related to uplift, erosion, faulting, and other orogenic issues. He dating is also used in a wide range of other applications, including dating young volcanic rocks, estimating meteorite thermal histories, thermal histories of sedimentary basins, and tracing the effects of wildfire on the earth's surface. In the ARHDL we work on applications such as these all over the world, and develop new ways to do and use He dating.
