Tectonics of Tibet

Part of "The Shear Zone" video channel. A look at the tectonic formation of the World’s largest plateau - generated by India-Asia collision, exploring the classic “thin viscous sheet” model for continental contractional tectonics and its neotectonics tests.

Nice. Such a great presentation, thank you

[@amiramiruddin9779]

It is good lecture for me and very usefull to understand the Himalaya and surrounding areas tectonic development. Thank you so much

[@salvatoreiaccarino945]

Hey Bob! Great lectures! Amazing job! Congratulations! I was wondering why not creat also a podcast related to this channel. It would be great! Best ❤

[@robbutler2095]

Nice idea... I've done one - published on the GeologyBites podcasts - on the Alps - www.geologybites.com/rob-butler

Why didn’t the Indian plate melt as it is subducted under the Eurasian plate instead of creating what looks like a double plate? Unless the subducting theory was disproved for the “ramming” theory.

[@robbutler2095]

The two theories are debated. But for sure some underthrusting by the Indian continent is highly likely - even putting aside geophysical imaging, we see it exhumed around Nanga Parbat for example. And this part of the Indian continental crust did indeed melt - a little bit... Check out the Parbat video on this site, and the link to an old film I made while at the OU!

The diagram at 6:50 is a plate tectonics illustration, in 1924 when Alfred Wegener"s concept was being rejected. Perhaps the right hand did not know what the left hand was doing.

[@robbutler2095]

Indeed so - rejected for all the wrong reasons... If you're into chasing this - try Naomi Oreskes book - "the Rejection of Continental Drift" (Oxford Uni Press, 1999 pbk) .. Those generally on the right side of history in the US dodged the debate and went off to look at mountain belts without tectonics ... more on this to follow!

A very well made video supporting an easy to understand lecture.

thanks!

glad you liked it!

[@MrTomcat104]

Fantastic explanation, even a layman like me can understand.

Thanks - glad you enjoyed it!
