Abstract [en]

The western margin of the Greenland craton has been much

less stable in the Phanerozoic than previously thought. This

new insight has come from close integration of independent

data sets: geomorphological analysis of large-scale landscapes,

apatite fission track analysis (AFTA), onshore and offshore

stratigraphy and analysis of onshore fault and fracture sys -

tems. Each data set records specific and unique parts of the

event 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 the

uplifted 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 concluded

that the West Greenland mountains were formed by late

Neogene tectonic uplift (Fig. 1) and also provided new

insight into early Phanerozoic development. To understand

our model, we present the different methods and the results

that can be deduced from them.
