“…Tagami and Shimada (1996) discussed a ZPAZ between $230 and 320°C for a heating duration of about 10 6 years. Fission-tracks in zircon grains from Miocene to Pleistocene sandstones and Miocene to Pliocene rhyolites of two drill holes in a sedimentary basin in Japan give indications for a value above 200°C for the low temperature limit of the ZPAZ at a stable temperature of about 1 Ma (Hasebe et al 2003). Furthermore, results of laboratory annealing experiments point towards a similar temperature range of the ZPAZ (Yamada et al 1995;Tagami et al 1998).…”

The southwestern part of the Lower Saxony Basin (LSB) is characterized by gravity and magnetic anomalies and by an extremely high thermal maturity of organic matter. This was for many years attributed to a Late Cretaceous intrusion, but actually deep burial is being debated. The complex thermal history of the area has been studied by fission track analysis. Zircon data provide evidence for widespread (hydro)thermal activity during the Permian and Upper Jurassic/Lower Cretaceous. Apatite ages indicate a major cooling event in the mid Cretaceous ($89-72 Ma) reflecting the time of inversion of the LSB. During the Cretaceous, the cooling of the basin centre was rapid compared to the basin margins. Apatite fission track ages from borehole samples which are recently within the upper part of the APAZ indicate a young heating of the sedimentary sequences until present.

“…Zircon has been dated by the U-Pb method since the early 1950s (Larsen et al 1952), and was one of the first minerals to be dated with the fission-track (FT) method (Fleischer et al 1964). Because annealing of FTs in zircon commonly takes place at subgreenschist facies conditions on a geologic time scale, this dating method has mainly been used to study late-stage cooling, together with other chronometers (e.g., Zeitler 1985;Hurford 1986), or near-surface thermal histories (e.g., Hasebe et al 1997Hasebe et al , 2003. To accomplish this goal, zircon samples have been sampled at or below the surface in order to gain an on-site exhumation history.…”

“…The annealing of etchable FTs in zircon was shown to occur at 400-800 °C in short-term laboratory experiments (Carpéna 1992;Yamada et al 1995;Tagami et al 1998) and at 200-350 °C for geologic time spans (Tagami and Shimada 1996;Tagami et al 1995a;Brandon et al 1998;Hasebe et al 2003). In contrast, for the annealing of α damage in zircon under laboratory and geologic conditions, a variety of observations gives a very complex picture: Garver and Kamp (2002) showed that zircon color, which is a result of point defects in crystalline areas, is annealed during geologic time scales at reasonably low temperatures of 350-400 °C, i.e., at conditions above the FT PAZ.…”

A zircon fission track-annealing model is calculated on the basis of annealing experiments from the literature with induced tracks in α-decay event damage-free zircon samples. Empirically derived parallel and fanning equations for this "zero-damage" model yield an excellent fit to the data, with the fanning model providing slightly better statistical parameters. A comparison between annealing models with fanning iso-annealing lines but different α-decay event damage densities reveals that annealing temperatures and closure temperatures for the estimated partial annealing zone are highest for the zero-damage model.Compilations of existing geologic constraints on the zircon partial-annealing zone on one hand and the zircon closure temperature on the other show that these constraints do not or only partly overlap with curves of proposed models for the zircon partial-annealing zone and closure temperature. This finding is consistent with the fact that the annealing behavior of zircon from long-duration temperature evolutions is increasingly influenced by the accumulated α-decay event damage. Zircon samples of young age or low U content show a behavior closest to the predictions of the zero-damage model, and are in the predicted range of published models with low α-decay event damage density. For thermal events of more than 10 myr duration, however, constraints from field studies show marked differences from proposed partial-annealing zone boundaries of the zero-or low-damage models.The applicability of the zero-damage model is threefold.(1) It predicts correct closure temperatures in the case of very rapid cooling across the partial annealing zone where basically no α-decay event damage is accumulated. (2) It predicts an uppermost boundary for complete annealing of a mixture of zircon components of different age, as found in sedimentary samples, and in this case may be used as a thermometer. (3) It represents an important reference for the establishment of a more comprehensive model of zircon fission-track annealing that also includes the influence of α-decay event damage. For such a model, two different equations are discussed. However, additional detailed experimental and field data are needed for a more robust annealing model that includes the influence of α-decay event-damage annealing.

The eastern margin of the East European Craton (EEC) has a long lasting geological record of Precambrian age. Archaean and Proterozoic strata are exposed in the western fold-and-thrust belt of the Uralides and are known from drill cores and geophysical data below the Palaeozoic cover in the Uralides and its western foredeep. In the southern Uralides, sedimentary, metamorphic and magmatic rocks of Riphean and Vendian age occur in the Bashkirian Mega-anticlinorium (BMA) and the Beloretzk Terrane. In the eastern part of the BMA (Yamantau anticlinorium) and the Beloretzk Terrane, KAr ages of the <2-m-size fraction of phyllites (potassic white mica) and slates (illite) give evidence for a complex pre-Uralian metamorphic and deformational history of the Precambrian basement at the southeastern margin of the EEC. Interpretation of the K-Ar ages considered the variation of secondary foliation and the diagenetic to metamorphic grade. In the Yamantau anticlinorium, the greenschist-facies metamorphism of the Mesoproterozoic siliciclastic rocks is of Early Neoproterozoic origin (about 970 Ma) and the S1 cleavage formation of Late Neoproterozoic (about 550 Ma). The second wide-spaced cleavage is of Uralian origin. In the central and western part of the BMA, the diagenetic to incipient metamorphic grade developed in Late Neoproterozoic time. In postUralian time, Proterozoic siliciclastic rocks with a cleavage of Uralian age have not been exhumed to the surface of the BMA. Late Neoproterozoic thrusts and faults within the eastern margin of the EEC are reactivated during the Uralian deformation.
