Thermal annealing of fission tracks in apatite

SAXS study of ion tracks in San Carlos olivine and Durango apatite

“…In addition, different groups have studied the annealing properties of tracks in apatite [11][12][13][14] and olivine [4,15]. These experiments predominantly utilize chemical etching and investigate empirically the effect of annealing on the number density and length distribution of the etched tracks [11][12][13].…”

Possible Jurassic age for part of Rakaia Terrane: Implications for tectonic development of the Torlesse accretionary prism

“…In these situations, FT parameters of age and length are interpreted to infer the thermal history (time-temperature history) experienced by the sample host rocks. The systematics of annealing are now well known for FTs in apatite, both at laboratory and geological time-scales, and thermal histories can be interpreted and modelled routinely for the temperature range 110-50°C Green et al 1986Green et al , 1989Laslett et al 1987;Duddy et al 1988;Gallagher 1995;Gallagher et al 1998). For zircon, the temperature range over which partial annealing occurs at geological time-scales is less precisely known, but lies within the range 210-260°C (Tagami et al 1998;Brandon et al 1998).…”

Cretaceous to Miocene cooling of Austroalpine units southeast of the Tauern Window (Eastern Alps) constrained by multi-system thermochronometry

“…The long accepted closure tempe-rature concept (Dodson, 1973) is sound and viable in many cases, however, increased understanding of track annealing and diffusion kinetics in apatite and zircon (e.g. Fleischer et al, 1964Fleischer et al, , 1965Fleischer et al, , 1975Wagner, 1968;Green et al, 1986;Carlson, 1990;Ketcham et al, 1999;Wendt et al, 2002;Farley, 2000;Meesters and Dunai, 2002;Reiners et al, 2003Reiners et al, , 2004Barbarand et al, 2003;Flowers et al, 2007;Guenthner et al, 2013) and development of user-friendly modelling packages that invert measured thermochronological data into cooling trajectories, provide scientists with much more robust tools for quantitative reconstruction of thermal histories of rocks (e.g. Gallagher, 1995Gallagher, , 2012Gallagher et al, 2005Gallagher et al, , 2009Ketcham, 2005;Ketcham et al, 2000;Meesters and Dunai, 2002).…”

For closure temperature ranges we adopted the following values: K/Ar muscovite: ~430-375°C (Hames and Bowring, 1994;Kirschner et al, 1996); Ar/Ar muscovite: ~450-350°C (Hames and Bowring, 1994;Kirschner et al, 1996;Lips et al, 1996;Harrison et al, 2009); Ar/Ar biotite: 400-300°C (Grove and Harrison, 1996;Villa, 1998); zircon fission track: 300-200°C (Wagner and van den haute, 1992); apatite fission track: 120-60°C (Green et al, 1986 Ma, respectively (Kralik et al, 1987 Scharf et al, 2013;Wölfler et al, 2008Wölfler et al, , 2011Wölfler et al, , 2012 Selverstone, 1988;Genser and Neubauer, 1989;Fügen-schuh et al, 1997;Scharf et al, 2013;Schmid et al, 2013).
