A remarkable Eskimo harpoon from East Greenland

Greenland Fracture Zone–East Greenland Ridge(s) revisited: Indications of a C22-change in plate motion?

Transorbital injury from a harpoon involving the paranasal sinuses.

A harpoon accidentally entered the right eye of a 15-year-old boy. No loss of consciousness occurred. After neuro-radiological assessment, the object which had penetrated the sphenoid sinuses was removed without mishap. He made a good recovery but has, as permanent deficits, an inferotemporal field defect, diminished visual acuity with optic atrophy, a sensory pupillary defect and right ptosis....

Be ages from central east Greenland constrain the extent of the Greenland ice sheet during the Last Glacial Maximum

Traditional ice sheet reconstructions have suggested two distinctly different ice sheet regimes along the East Greenland continental margin during the Last Glacial Maximum (LGM): ice to the shelf break south of Scoresby Sund and ice extending no further than to the inner shelf at and north of Scoresby Sund. We report new Be ages from erratic boulders perched at 250ma.s.l. on the Kap Brewster pe...

Depleted spinel harzburgite xenoliths in Tertiary dykes from East Greenland: Restites from high degree melting

A new collection of mantle xenoliths in Tertiary dykes from the Wiedemann Fjord area in Southeast Greenland shows that this part of the central Greenland craton is underlain by highly depleted peridotites. The samples are mostly spinel Ž . harzburgites with highly forsteritic olivines Fo , average Fo . This, together with unusually high modal olivine 87– 94 92.7 Ž . contents 70–)95% , places th...

Disentangling Diagenesis From the Rock Record: An Example From the PermoTriassic Wordie Creek Formation, East Greenland

The measurement of isotope ratios in sedimentary rocks deposited over geological time can provide key insights to past environmental change over important intervals in the past. However, it is important to be aware that secondary alteration can overprint the original isotopic records. We demonstrate this principle using high-resolution carbon, sulfur, and oxygen isotope measurements in organic ...
