Our zealot is still struggling with the buoyancy principle... pathetic

That slabs are less dense than the mantle? Certainly not.

Yes they are. All the seismic data prove it.

Whatever, in plate tectonics, if the slab were not denser than the
mantle it would not sink. Period.

Whatever? Wrong answer. [...]

Idiot who ignores the basic principle of buoyancy! whatever the weigth,
if the the slab is not denser, it won't SINK down to the bottom of the
upper mantle.


When something heavy sits on top of the buoyant material (i.e., place the
weight of your hand on top of a ballon sitting on water), it can sink.
That
"something" is the hanging wall plate.

Unbelievable... Ron Yates reinventing plate tectonics...

This is standard to plate tectonics, my dear fellow.

Certainly not. Despite Plate tectonics does not make much sense, it is
not to the point to claim that lithosphere that is less dense than the
mantle would sink to the bottom!

The issue, my dear Ron, is that in plate tectonics, the "hanging wall
plate" is made of continental lithosphere that is less dense than the
oceanic lithosphere and therefore "float" over it. So, it can't make it
sink deep into the mantle.

30 miles of continental crust sitting on anything can make it sink, [...]

Idiot, the upper mantle is 660 km thick, a piece of lithosphere that is
less dense than the mantle won't sink to the bottom, it will float over
it. In order to sink, it must be denser.

Your fantasy physics tells a lot about you credibility. And I remind
everybody that you have a master in geology! Pathetic.
