It’s springsummertime in Oslo! Sun! 20 plus! Hepaticas are in full bloom on the Cambrosilurian on Hovedøya!
Any better time for one last escape back to the lovely, cold Arctic? We have went from the basement and all the tectonics it has suffered, through the Paleozoic rifts, the Mesozoic seas and dino tracks, Tertiary coal and, now, to our time.
Geology is still very active in shaping Svalbard. Glaciers cover most of the archipelago, they carve out valleys and fjords, grinding the islands further down. The waste products, the glaciers dump in the sea just off the tresholds of the fjords. No respect for environmental regulations, those glaciers.
Let’s don our quack-quack suits one more time and board the RIB to take a look at today’s glacier geology in action!
Quack, quack! here is yours truly looking like something from outer space.
Quaternary fold’n’thrust belt! The glaciers have light and dark layers, because of variable dirt content. As they float along, the snow recrystallises to ice, and deformes in a plastic flow, to form bands just like in a gneiss, and with folds and thrusts.
Red ducks in a row, waiting for the glacier to start the show.
And here we go! Splash! :)
And then we say farewell to Svalbard, With some images of the glaciers from above, as mighty rivers of ice towards the sea…
