Perhaps the most straightforward geologic processes to constrain with (U-Th)/He thermochronology are those that cause the direct cooling of rocks, including exhumation caused by erosion (e.g., Kirby et al., 2002; Ehlers and Farley, 2003) or normal faulting (e.g., Stockli et al., 2000; Reiners et al., 2002 ). Date-elevation sampling strategies ...

232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th.The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days. 233 Pa decays (negative beta …

spiked with suitable uranium and thorium isotopes (235 U and 230 Th) and the resulting 238 U/ 235 U and 232 Th/ 230 Th ratios are determined. These spikes were chosen because of their low or zero abundance in natu-ral samples, but there are other options (e.g., 229 Th). The advantage of using isotope spiking is twofold: the
