Wonderful explanation! It is finally all coming together for me. However, at the graduate level there is great emphasis on the fact that ophiolite complexes are found on land. There has been historic debate on how this happens. A video on that would be interesting.
According to Eldridge Moores (RIP), they form when an oceanic plate is consumed by two continental plates that smash into each other, scraping the ophiolite sequence onto land which then becomes alpine mountains from the continent-continent collision
I don’t really understand how that explains how they are formed... I mean you explained how the oceanic lithosphere was made. Yet ophiolites are the succession of these layers (characterising oceanic Lithosphere) that are found in some mountains if it’s in the ocean you still talk about oceanic lithosphere not ophiolites 😂. I wanted to know how they manage to get up in the mountains with all the obduction and stuff ...
When the plate subducts some of the rock is accreted onto the edge of the continent, including rocks on the sea floor. Then uplift associated with the tectonic collision moves that accreted seafloor high into the mountains where it is exposed after sedimentary layers on top erode away
Iv seen pillow basalts / pillow lavas in real life I can see the resemblance to pillows! ! You have a lovely voice for teaching I could listen all day to it , wish you were my teacher at college , then perhaps after studies you could come n examine my pillow :)x
