What? The wedge is not recycled back! it is a one way ticket toward the
surface. Bit of overthrusted lithosphere is getting buried, and that's
all. You will never get it.

Idiot, "overridden" not "overriding"

Idiot, you confuse the rising wedge below the volcanic arc and the
overthrusting forearc.

Oh boy, oh boy.
Look again:
<http://nachon.free.fr/overthrust/Philippines-extrusions.jpg>
The Ryukyu orocline is moving South-East over the Philipine ocean floor.
There is a marginal sea at the back of the arc, East China Sea, and that
is where extension takes place like at any back-arc.

All alcoholics say that.
