A multi-disciplinary study of Phanerozoic landscape development in West Greenland

• The western margin of the Greenland craton has been muchless stable in the Phanerozoic than previously thought. Thisnew insight has come from close integration of independentdata sets: geomorphological analysis of large-scale landscapes,apatite fission track analysis (AFTA), onshore and offshorestratigraphy and analysis of onshore fault and fracture sys -tems. Each data set records specific and unique parts of theevent chronology and is equally important to establish a con-sistent model. A key area for understanding the Mesozoic-Cenozoic landscape evolution and into the present is theuplifted part of the Nuussuaq Basin, where remnants of pla-nation surfaces cut across the Cretaceous to Eocene sedimen-tary and volcanic rocks. Our integrated analysis concludedthat the West Greenland mountains were formed by lateNeogene tectonic uplift (Fig. 1) and also provided newinsight into early Phanerozoic development. To understandour model, we present the different methods and the resultsthat can be deduced from them.
