“…The etching response of zircon is related to radiation damage in the grain (Gleadow, 1978;Kasuya and Naeser, 1988;Garver et al, 2000a). The result of the radiation damage is that grains with high radiation damage etch easily and tracks are quickly revealed in a few hours.…”

“…The purpose of this study is to examine whether it is possible to detect all major cooling age components in a drainage area with one detrital sample, despite the variable etching response of detrital zircon (Naeser et al, 1987;Kasuya and Naeser, 1988). Furthermore, we are also interested to see, if detrital zircon FT results are reproducible.…”

Fundamental aspects of detrital zircon fission-track analysis in provenance and exhumation studies include etching of fission-tracks in zircon, decomposition of grain-age distributions, detection of major bedrock age components, and reproducibility of results. In this study, we present new detrital zircon fission-track data of sediment samples from eight Italian rivers, draining the European Alps and previously published data from the Rhône delta in southeastern France. These samples are used to demonstrate that variable etching rates in detrital zircon, which have been shown elsewhere to necessitate a multi-etch procedure during sample preparation, are not a significant problem for zircons from the Alps. Etching response in zircon is a function of radiation damage, principally caused by α-decay. Spontaneous fission-track density can be used as a proxy for total radiation damage. We use spontaneous track density, fission-track cooling age, and uranium content to define a "window of countability" for detrital zircon. We also show that detrital zircon fission-track results are reproducible, by comparing results from modern sediments from the same river drainage. The results also compare well with the known distribution of bedrock cooling ages in each drainage. On a regional scale, our data illustrate that a few samples can provide an overview of the fission-track age pattern of a whole orogen, which is useful for exhumation and provenance studies.

“…These estimates represent 10% and 90% annealing isopleths (strictly not the top and bottom of a PAZ), and are assigned to the component of zircon grains having the youngest FT ages in their samples, considered to be those which had the greatest amount of radiation damage and most susceptibility to annealing. This assignment is based on the fact that the thermal stability of fission tracks in zircon decreases with increasing a-damage (Kasuya and Naeser, 1988). Together, these points suggest that the temperature limits of a ZPAZ are dependent upon the timetemperature history of the sample host rocks, the degree of radiation damage contained in the crystals on entering the PAZ, and whether or not the stratigraphic/structural extents of fossil PAZs are picked from the central ages for samples or from a subset (least thermally stable) of the dated grains within samples.…”

“…This estimation was made without quantification of damages of the crystal lattice by alpha-decay. The accumulation of radiation damages caused by alphadecay is an important factor influencing the temperature range of the ZPAZ which can substantially lower its temperature boundaries (Kasuya and Naeser 1988;Brandon et al 1998). This is especially valid for samples, which were never heated up to temperatures exceeding the ZPAZ for a time allowing for total annealing (Rahn et al 2004;Timar-Geng et al 2004).…”

“…2) is probably related to the different annealing kinetics of the individual grains. The distinct annealing behaviour is probably related to variable amounts of accumulated a-damage and/or compositional variations (Green et al 1985;Kasuya and Naeser 1988;Brandon et al 1998). …”

The thermal history of the south-westernmost Black Forest (Germany) and the adjacent Upper Rhine Graben were constrained by a combination of apatite and zircon fission-track (FT) and microstructural analyses. After intrusion of Palaeozoic granitic plutons in the Black Forest, the thermal regime of the studied area re-equilibrated during the Late Permian and the Mesozoic, interrupted by enhanced hydrothermal activity during the Jurassic. At the eastern flank of the Upper Rhine Graben along the Main Border Fault the analysed samples show microstructural characteristics related to repeated tectonic and hydrothermal activities. The integration of microstructural observations of the cataclastic fault gouge with the FT data identifies the existence of repeated tectonic-related fluid flow events characterised by different thermal conditions. The older took place during the Variscan and/or Mesozoic time at temperatures lower than 280°C, whereas the younger was probably contemporary with the Cenozoic rifting of the Upper Rhine Graben at temperatures not higher than 150°C.
