You just earned yourself a new subscriber. What an amazingly clear, concise and informative presentation on Sedimentary Basins! I really appreciate your annunciation and pacing of your narration. It made understanding what you were presenting all that much easier to comprehend. Bravo Mr. Butler!

Thank you, this was an awesome explanation!

Glad you found it useful

John Cosgrove who studied the Zagros intensely was my professor

Hi sir, thank you for sharing.

Thanks. You explained why sediments can be accumulated in some areas and then gave many examples. There are also vocanos, oil fields, and some Au-Cu deposits in Congo (B and K). Should Congo basin also be transformed by the Atlantic spreading process?

I listened again. And I have a question on the relations between the Orogen and basins, they should grow in different dynamic background. Take the Ganges basin as example, it has changed by the Himalayas in the north side. Can we say this is the basin inversion phenomena? If so, then the Tibet plateau is initiated from an extensional region which elongated N-S at first, indicated by the South Tibet detachment zone to the north and the Ganges basin to the south. Before that huge "extensional region", there are may be another episode of late Paleogene orogen. And the relations between that older orogen and this huge "extensional region" is superposition.

@@user-ij3qo6xl9s Not all sedimentary basins form by lithospheric extension - the Ganges basin is a flexural basin - formed by lithosheric loading by the stacked crust of the Himalayas (see video on topic). As the Himalayas advance they reprocess their own detritus... this isn't inversion - in the modern tectonic use of the term (it's what emergent thrust belts do). Note that E_W extension in Tiber, radial thrusting in the Himalayas (and on flanks of Tibet) with strike-slip (e.g. Kun Lun Fault) are all synchronous - they're active today (see focal mechanisms in the Tibet video). Hope that helps....

is Jos Butler your relative ? nice explanation though, Thanks!
