The Jurassic of North-East Greenland: A new Middle–Upper Jurassic succession on Hold with Hope, North-East Greenland
A succession of marine, Jurassic sediments was recently discovered on Hold with Hope, North-East Greenland. The discovery shows that the area was covered by the sea during Middle–Late Jurassic transgressive events and thus adds to the understanding of the palaeogeography of the area. The Jurassic su...
