“…This explanation is in accord with studies reported by several workers from elsewhere in the Fennoscandia shield (e.g. Zeck et al 1988;Nikishin et al 1996;Samuelsson & Middleton 1998;Larson & Tullborg 1998;Larson et al 1999Larson et al , 2006Cederbom et al 2000;Cederbom 2001;Lorencak 2003;Huigen & Andriessen 2004;Murrell & Andriessen 2004;Kohonen & Rämö 2005). Furthermore, the AFT data show a low proportion of long tracks in their HCTL distributions, and this is in accordance with published thermal history models for eastern Fennoscandia, which suggest that final cooling (from c. 60 to 65 8C) occurred relatively late (Late Cretaceous -Early Tertiary) in the cooling history (Lorencak 2003;Murrell & Andriessen 2004).…”

We assess the proposal of Hendriks & Redfield (Earth and Planetary Science Letters, 236, 443-458, 2005) that cross-over of the predicted apatite fission track (AFT) . (U-Th-Sm)/ He (AHe) age relationship in the southeastern Fennoscandian shield in southern Finland reflects a-radiation-enhanced annealing (REA) of fission tracks at low temperatures and that more robust estimates of the denudation history are recorded through reproducible AHe data. New AHe results from southern Finland showing variable dispersion of single-grain ages may be biased by different factors operating within grains, which tend to give a greater weighting towards older age outliers. AHe ages from mafic rocks show the least dispersion and tend to be consistently lower than their coexisting AFT ages. In general, it is at the younger end of the single-grain variation range from such lithologies where most meaningful AHe ages can be found. AHe data from multigrain aliquots are, therefore, of limited value for evaluating thermal histories in southern Finland, especially when compared against coexisting AFT data as supporting evidence for REA.New, large datasets from the southern Canadian and Western Australian shields show the relationship between AFT age, single-grain age or mean track length as a function of U content (determined by the external detector method). These do not display the moderately strong inverse correlations previously reported from southern Finland in support of REA. Rather, the trends are inconsistent and generally exhibit weak positive or negative correlations. This is also the case for plots from both shields, as well as those from southern Finland, where AFT parameters are plotted against effective U concentration [eU] [based on U and Th content determined by inductively coupled plasma-mass spectroscopy (ICP-MS)], which weights decay of the parents more accurately in terms of their a-productivity. Further, samples from southern Finland yield values of chi-square x 2 .5%, indicating that there is no significant effect of the range of uranium content between grains within samples on the AFT ages, and that they are all consistent with a single population.The oldest AFT ages in southern Finland apatites (amongst the oldest recorded from anywhere) are found in gabbros, which also have the highest Cl content of all samples studied. We suggest, that it is Cl content rather than REA that has influenced the annealing history of the apatites, which have experienced a history including reburial into the partial annealing zone by Caledonian Foreland basin sedimentation. The study of apatite from low U and Th rocks, with relatively low levels of a-radiation damage may provide the most practical approach for producing reliable results for AFT and AHe thermochronometry studies in cratonic environments.

“…In the Palaeozoic, marine transgression resulted in a sedimentary cover (Koistinen et al, 2001) which, according to apatite fission track analyses (Zeck et al, 1988;Tullborg et al, 1996;Larson et al, 1999;Cederbom, 2001), reached a thickness of several km. Subsequent uplift caused erosion leading to a near complete removal of the sedimentary cover in late Tertiary (Lidmar-Bergströ m, 1996;Cederbom, 2001;Sö derlund et al, 2005).…”

“…Available apatite fission track (AFT) data (Fig. 58) document a broad, regional-scale pattern of post-rift denudation and uplift (Rohrman et al, 1995;Cederbom, 2001;Hendriks and Andriessen, 2002;Rohrman et al, 2002;Huigen and Andriessen, 2004;Murrell and Andriessen, 2004;Redfield et al, 2004;Hendriks and Redfield, 2005). However, there is a lack of data on denudation rates at the finer resolution scale required for constraining numerical models for surface and deeper lithospheric or even asthenospheric processes.…”

TOPO-EUROPE addresses the 4-D topographic evolution of the orogens and intra-plate regions of Europe through a multidisciplinary approach linking geology, geophysics, geodesy and geotechnology. TOPO-EUROPE integrates monitoring, imaging, reconstruction and modelling of the interplay between processes controlling continental topography and related natural hazards. Until now, research on neotectonics and related topography development of orogens and intra-plate regions has received little attention. TOPO-EUROPE initiates a number of novel studies on the quantification of rates of vertical motions, related tectonically controlled river evolution and land subsidence in carefully selected natural laboratories in Europe. From orogen through platform to continental margin, these natural laboratories include the Alps/Carpathians-Pannonian Basin System, the West and Central European Platform, the Apennines-Aegean-Anatolian region, the Iberian Peninsula, the Scandinavian Continental Margin, the East-European Platform, and the Caucasus-Levant area. TOPO-EUROPE integrates European research facilities and know-how essential to advance the understanding of the role of topography in Environmental Earth System Dynamics. The principal objective of the network is twofold. Namely, to integrate national research programs into a common European network and, furthermore, to integrate activities among TOPO-EUROPE institutes and participants. Key objectives are to provide an interdisciplinary forum to share knowledge and information in the field of the neotectonic and topographic evolution of Europe, to
