“…Scapolite BB1 with 3.1 wt. % Cl was used as the Cl calibration standard (Kendrick, 2012) and Durango apatite analysed as an unknown gave a Cl concentrations within the previously reported range (Marks et al, 2012;Nadzri et al, 2017).…”

“…This results from the large aspect ratios of the tracks that are approximatly 10 nm in diameter but tens of micrometers long 15 . The variation of the scattered intensity along the narrow curved streaks contains information about the radial density profile of the tracks 3,15 . Figure 1(d) shows a scattering image after annealing at 250 °C for the duration of 5 min under a pressure of approximately 1 GPa.…”

“…Natural so called 'fission tracks' are comparable in size and structure to ion tracks with a diameter of approximately 10 nm and lengths of several micrometres, as the fundamental mechanisms for their generation are the same as for ion tracks. Ion tracks generated under controlled conditions in large accelerator facilities are thus often used as a proxy to better understand important parameters and relevant properties of fission tracks 3 .…”

“…The ion tracks consist of amorphous material with a density different from that of the surrounding crystalline matrix 15 . As SAXS is sensitive to density changes on nanometre length scales, ion tracks in apatite can be readily measured using the technique 3,15,16 . Compared to the analysis using chemically etched tracks, where the original track damage is removed, SAXS has the great advantage of providing direct information on the track damage without the use of chemical etching.…”

“…Compared to the analysis using chemically etched tracks, where the original track damage is removed, SAXS has the great advantage of providing direct information on the track damage without the use of chemical etching. We have previously demonstrated that SAXS is well suited for the study of ion tracks in minerals with high precision and with sufficient time resolution for in situ measurements 3,15 . Annealing under pressure was performed using heatable diamond anvil cells (DACs).…”

Fission track thermochronology is routinely used to investigate the thermal history of sedimentary basins, as well as tectonic uplift and denudation rates. While the effect of temperature on fission track annealing has been studied extensively to calibrate the application of the technique, the effect of pressure during annealing is generally considered to be negligible. However, a previous study suggested elevated pressure results in a significantly different annealing behaviour that was previously unknown. Here, we present a method to study track annealing in situ under high pressure by using synchrotron-based small angle x-ray scattering (SAXS). To simulate fission tracks in a controlled environment, ion tracks were created in apatite from Durango, Mexico using 2 GeV Au or Bi ions provided by an ion accelerator facility. Samples were annealed at 250 °C at approximately 1 GPa pressure using diamond anvil cells (DACs) with heating capabilities. Additional in situ annealing experiments at ambient pressure and temperatures between 320 and 390 °C were performed for comparison. At elevated pressure a significantly accelerated annealing rate of the tracks was observed compared with annealing at ambient pressure. However, when extrapolated to geologically relevant temperatures and pressures, the effects become very small. The measurement methodology presented provides a new avenue to study materials behaviour in extreme environments.
