NC Greenland NG2: Three-dimensional stratigraphic Horizon in the Northern Central Greenland ice sheet (37.5 ka)

The NG2 3D horizon is located in northern central Greenland and covers an area of approximately 690 x 55 km and reaches almost from the eastern to the western outlet systems. The age of NG2 is 37.5 ± 2.1 ka (thousand years). NG2 extends in the east into the NEGIS trunk and shows in this area similar...

Description
Summary:The NG2 3D horizon is located in northern central Greenland and covers an area of approximately 690 x 55 km and reaches almost from the eastern to the western outlet systems. The age of NG2 is 37.5 ± 2.1 ka (thousand years). NG2 extends in the east into the NEGIS trunk and shows in this area similar short-wavelength folds, which are observed in the NEGIS shear margins. Furthermore, NG2 resembles several cylindrical upright folds in the eastern and western edges of the horizons. The fold axes of the cylindrical folds in the west trend approximately west, whereas the trend of the cylindrical folds in the east trend north. In the central-eastern area, we find a large bump in the bed topography due to the paleofluvial mega-canyon, which is imprinted in the 3D horizons mimicking this bed depression. In the central-west, we find cylindrical upright folds trending in two different directions (north and north-west).
