In Kronprins Christian Land the end-Cretaceous Kronprins Christian Land Orogeny constitutes a fairly narrow, NW-SE oriented transpressional zone of deformation characterized by a high-intensity axis with diverging thrust displacement and a rapid, symmetric drop in deformational intensity and - probably - thermal alteration away from the axis. Strike-slip dominated deformation is centered along a system of prominent, reactivated along-axis faults, whereas compressional structural elements dominate in the areas between the main faults. The two axial tectono-stratigraphic terranes represent, respectively, the north and south verging flanks of a major flower structure. The Kilen Terrane exposes upper stockwerk level deformation characterized by oblique, en échelon domal folds with minor reverse faults and late, small-scale tear faults. The lngeborg Terrane exposes deformation from a lower stockwerk level characterized by thrust fault ramp-and-flats, thrust fault folding, as weil as by zones of chaotic cataclastic breccias, Vertical separation between the two levels is approximately 3 km; in spite of this, localized high-pressure zones in the lower level have reached greenschist fades metamorphic grades.
