I try, but sometimes it's inadvertent. At any rate, you're probably done trying to document the expanding earth with peer-reviewed publications. There's just nothing that prevents cool metasomatized lithosphere from subducting. You're still spouting bullshit to try to deny it.
You are building a strawman. I never said that a slab cannot sink. My point is that the driving force that makes it sink is the load of what is progressively pilling up on it.
You still did not explain me what physics support that a slab of brittle lithosphere can drag thousands km of brittle lithosphere without a glitch.
Florian, you have to admit that subduction is the only explication for the constant radius.
South America is moving 34mm/year to the west relative to the mid-atlantic ridge.
Spreading ridge in the Pacific 86mm/year, direction east.
So if are able to count, the subduction speed at Chile = 120mm/year !!
Data is proving this number so I'm starting to take the side of those friendly people around here that are supporters of the plate tectonics theory.
