“…The application of the AFT data in the study of the North Atlantic paleolandscapes is the subject of debates (e.g., Chalmers et al, 2010;Green et al, 2011;Green et al, 2013;Japsen et al, 2013;Nielsen et al, 2009;Nielsen et al, 2010a;Pedersen et al, 2013;Redfield, 2010). Without entering details of the method and application of the AFT data to local geology, we demonstrated an overall correlation between AFT data and exhumation below our modeled paleosurface for Scandinavia.…”

“…How reasonable is this assumption? Chalmers et al (2010) and Japsen et al (2013) demonstrated that similar ages and track distributions in individual samples can be explained equally well by monotonic cooling or by episodic heating and cooling. Application of that observation to a large data set, however, is not trivial.…”

“…The downside of such an approach is the lack of widely accepted theoretical background for interpretation of AFT data onto the thermal and exhumation history. That type of interpretation is the subject of continuing discussions (e.g., Chalmers et al, 2010;Green et al, 2011;Hendriks et al, 2010;Nielsen et al, 2010a;Redfield, 2010). In contrast, in this study, we model paleolandscapes using the topographic data; and test this model statistically against AFT data, particularly against trends (or breaks of trends) in AFT ages.…”

“…Recently, Nielsen et al (2009Nielsen et al ( , 2010 argued that the present high topography is mainly a long-lived remnant of the Caledonian Mountains. This view has generated some debate (Chalmers et al 2010;Nielsen et al 2010).…”

Upper-mantleP- andS-wave velocities across the Northern Tornquist Zone from traveltime tomography

et al. 2015

S U M M A R YThis study presents P-and S-wave velocity variations for the upper mantle in southern Scandinavia and northern Germany based on teleseismic traveltime tomography. Tectonically, this region includes the entire northern part of the prominent Tornquist Zone which follows along the transition from old Precambrian shield units to the east to younger Phanerozoic deep sedimentary basins to the southwest. We combine data from several separate temporary arrays/profiles (276 stations) deployed over a period of about 15 yr and permanent networks (31 stations) covering the areas of Denmark, northern Germany, southern Sweden and southern Norway. By performing an integrated P-and S-traveltime analysis, we obtain the first high-resolution combined 3-D V P and V S models, including variations in the V P /V S ratio, for the whole of this region of study. Relative station mean traveltime residuals vary within ±1 s for P wave and ±2 s for S wave, with early arrivals in shield areas of southern Sweden and later arrivals in the Danish and North German Basins, as well as in most of southern Norway. In good accordance with previous, mainly P-velocity models, a marked upper-mantle velocity boundary (UMVB) is accurately delineated between shield areas (with high seismic mantle velocity) and basins (with lower velocity). It continues northwards into southern Norway near the Oslo Graben area and further north across the Southern Scandes Mountains. This main boundary, extending to a depth of at least 300 km, is even more pronounced in our new S-velocity model, with velocity contrasts of up to ±2-3 per cent. It is also clearly reflected in the V P /V S ratio. Differences in this ratio of up to about ±2 per cent are observed across the boundary, with generally low values in shield areas to the east and relatively higher values in basin areas to the southwest and in most of southern Norway. Differences in the V P /V S ratio are believed to be a rather robust indicator of upper-mantle compositional differences. For the depth interval of about 100-300 km, thick, depleted, relatively cold shield lithosphere is indicated in southern Sweden, contrasting with more fertile, warm mantle asthenosphere beneath most of the basins in Denmark and northern Germany. Both compositional and temperature differences seem to play a significant role in explaining the UMVB between southern Norway and southern Sweden. In addition to the main regional upper-mantle velocity contrasts, a number of more local anomaly features are also outlined and discussed.

“…There has, consequently, been considerable debate about for how long high mountains in Norway have existed (e.g. Lidmar-Bergström et al, 2000;Lidmar-Bergström and Bonow, 2009;Chalmers et al, 2010;Nielsen et al, 2009aNielsen et al, ,b, 2010aGabrielsen et al, 2010a,b).…”
