Eclogites at Cignana - a walk into a subducted ocean

[@danieljulian4676]

Splendid! I came for the scenery and stayed for the thermobarometry.

Can I please use this as the title of my thesis? Lol

[@przemekczapla7264]

Thank you Professor. Great story

[@robbutler2095]

Thanks!

[@philwaters9751]

Outstanding. Thanks (again) Rob for yet another superbly cross linked lecture... 👌

[@lindafowler4274]

What super rocks! Love that you can see so much in hand specimen, and then your PT burial/exhumation explanations. That was a part of the OU hard rock course I really enjoyed (30 years ago now) and it all cam flooding back

[@robbutler2095]

Yes indeed - always advantageous to have coarse grained rocks for metamorphic ponderings!

As always, an excellent and educational video in a wonderful landscape. It seems have come across core boring holes more and more over times, a site I visited a couple months ago had dozens of it, borderline vandalism in the name of science? Well, it was an interesting impact generated tsunami deposit, to my surprise I came also across three different types of Boudinage within 30m of each other (two on different clast, one in the breccia after deposition), apparently totally ignored by the sedimentologists…..

[@robbutler2095]

Rock coring goes beyond borderline vandalism - it's unethical and recognised as such by some journal publishers now. It won't repair the damage done but research papers should be rejected if sampling of critical outcrops leads to this type of damage....

[@ThomasEckhardt]

@@robbutler2095, I understand if coring is done because the exact geometry is critical, such as paleo magnetic studies, it however should not be a replacement for the old hammer and chisel method!

Thank you very much

[@paularcher9176]

Wish I had Rob as a teacher at University in geology!

Do you think you might be able to do a video on rock metamorphosis during various stages of subduction? Maybe include the sedimentary rocks that take the ride down. I’m curious about the pressures at different depths and how the rocks undergo metamorphosis and become denser.

[@robbutler2095]

nice suggestion. Can do - but not straight away.

[@PlayNowWorkLater]

@ awesome appreciate it. No problem waiting. There were a lot of components in this video that I was looking for. And I think I’ll find more in your other videos. Jumping on to the Matterhorn next as you suggest in this one. Cheers! Thanks for doing what you do

[@aboubaker1071]

Amazing

[@benwinkel]

I highly appreciate these video's from you. Do you make these on your vacation or are they actual field trips? I don't know if you're familiar with prf Nick Zentner from Washington State University, but i have been enjoying his video's for some years with great pleasure. Being from The Netherlands however, i had been on the lookout for similar material about European geology and i am very greatful that i found your channel! Thank you for sharing your knowledge with us.

[@robbutler2095]

Glad you're enjoying the films. To answer your question - it's a bit of both, along with making ones that face my students directly - as technical demonstrations. Thanks for pointing me at Nick Zentner's channel....

i am having a strange sensation of déjà vu... 😃

[@alexdrockhound9497]

reupload?

[@robbutler2095]

yes - a quick correction... and tidy of a graphics glitch.... all good now I hope!
