“…Samples within the HePRZ, however, can display greater ZHe age variance and dispersion due to kinetic or grain specific variations modulating the effective He diffusivity, such as radiation damage, grain size and morphology, parent nuclide distribution (zoning), or variable He age inheritance (e.g., Guenthner et al, 2013;Guenthner, Reiners, DeCelles, & Kendall, 2014;Guenthner, Reiners, & Tian, 2014;Ketcham et al, 2013;Nasdala et al, 1995Nasdala et al, , 2001Nasdala et al, , 2004Reiners et al, 2002;Reiners & Farley, 2001). Hence, partially reset detrital samples represent a particular challenge when trying to reconstruct thermal histories and perform source-to-sink analyses due to common large intrasample ZHe age dispersion (e.g., Thomson et al, 2019).…”
