Summary: | International audience A compilation of fission track data is presented here to show from where fission track data are available in Fennoscandia and to highlight potential targets for future research. Because of the relatively small number of fission track data for zircon and titanite, emphasis is put on apatite fission track data. Because of the constraints the apatite fission track database puts on vertical movements, it is a valuable tool for example for work on regional geomorphology and can be used as a baseline for onshore offshore correlations. On the basis of sample elevation, rock type, apatite chemistry, analytical approach and data quality, a selection of apatite fission track ages and mean track lengths are presented to focus attention on first order patterns in the available datasets. The patterns of ages and mean track lengths are clearly representative of Mesozoic and Cenozoic vertical movements along the present-day Norwegian Atlantic margin, and of Paleozoic and older vertical movements further into the cratonic interior. Previously published interpretations of the available data are discussed here in brief. The current compilation will be updated when new data become available, and be available as an electronic supplement from the Geological Survey of Norway. |
