Step 3 (Fig. 11) illustrates the second phase, during which a hole is formed in the LTFL, and a piggyback imbricate fan of UTFL thrust sheets is piled up in the hole. keywords: andersen; area; basal; bugt; complex; deformation; décollement; décollement surface; fanø; fault; fig; glaciotectonic; ltfl; north; pedersen; s.p; section; sf1; sf2; structures; study; surface; thrust; utfl cache: geusb-8386.pdf plain text: geusb-8386.txt item: #520 of 522 id: geusb-8387 author: Colgan, William; Fahrner, Dominik; Luetzenburg, Gregor; Løkkegaard, Anja; Nielsen, Eva Sofie Bendix; How, Penelope; Rutishauser, Anja; Solgaard, Anne; Fausto, Robert S; Kjeldsen, Kristian K; Shields, Christopher; Spanggård, Henrik; Smith, Patrick; MacGregor , Joseph A; P.

Water samples were collected from well-mixed areas of the rivers, free from visible animal droppings, typically a few metres from the riverbank. keywords: concentration; data; greenland; meltwater; samples; sediment; water cache: geusb-8391.pdf plain text: geusb-8391.txt
