    Fold, or not to fold…that is the question.

    A Random Roadcut from Iceland! Great fun! Thank you, Shawn. I was guessing that it might have been pushed up from below by a magmatic intrusion. An overlay on existing topography did not occur to me.

    When i was in iceland a year ago i stopped at exactly this spot and i had a heated discussion with my mom wether this is a fault or (my point of view) an erosion phaenomena. finally cleared that dispute right now

    Makes me think of the snow drifts that extend out from the corners of your roof.

    It looks like a roof. Before this event, I didn't even know where Iceland was or anything about it. I had to google. And googling I've been doing. Everything about Iceland is so interesting. And learning about volcanos and lava here has been likewise enjoyable!

    Thanks Shawn. To be fair, I was struggling to see what it was because of the low intensity setting of my screen, and thought that it was a small cinder cone.

    I think you're right; there's no sign of folding in the stratum below it.

    I thought it a hinge joint in a basalt flow where two sections of floating crust hit square and pitch up. I see the same thing in ice flows in rivers and pressure ridges in sea ice.

  • @richardreid6377
    @richardreid6377 Год назад

    I was thinking the remains of an eroded off cinder cone, with the bulk of the cone having been where you were filming from.

    Is there a fold near Grindavik to indicate any knowledge of an approaching eruption in the new surrounding area ?

    @markpashia7067 Год назад +2

    Nice. Very helpful even for those who have no background. Question: Could it be as you say, but the original landform was from a prior fold? In other words, a combination of both with different dates.

    • @shawnwillsey
      @shawnwillsey  Год назад +2

      Doubtful. Iceland straddles a divergent boundary so most of the stress is extensional (stretching). The compressive forces needed for this type of fold are not prevalent.

  • @TomUlcak
    @TomUlcak Год назад

    Why couldn't it be just simply lava flow that is following the contour of the land. Or, maybe the angle of the vent opening would emit lava flow almost horizontally with the volume of flow causing a faster moving flow followed by a slowing of the flow creating a backup causing fluctuation in depth and angle of the flow?

    • @jackprier7727
      @jackprier7727 Год назад +1

      The observed deposit is not from any lava flow, but rather chunks and hunks and sludge thrown out of the volcano-

    • @TomUlcak
      @TomUlcak Год назад

      @@jackprier7727 or, a lava flow pushed chunks and hunks and sludge and mixed with it.

    Is the lake at Kleifarvatn a caldera?

    • @shawnwillsey
      @shawnwillsey  Год назад

      No. Just a low area surrounded by higher volcanic terrain.

    Lava flow?

    • @shawnwillsey
      @shawnwillsey  Год назад +1

      No. It is made of pyroclastic material, ash and larger particles that were exploded from vent into the air.

    I would imagine any compression based feature would not exist in Iceland.

    • @ericfielding2540
      @ericfielding2540 Год назад +1

      Yes, Iceland is an extensional zone, so compression would be surprising.
