DF? Response?

I got one. They found evidence of tectonic (accretion). Not plate
tectonic. Obviously, Earth expands regularly since its formation.

"The materials were formed as seafloor along a
spreading center and ***accreted*** to a continental plate and just stuck
there,
surviving almost unscathed for as long as 3.8 billion years."


I guess I have to point out that crust as to be formed before it can
subduct, and when it subducts, it gets destroyed,

Rubbish! It's subduction that forms the ocean floor. Haven't you
heard of slab-pull? What have you got for brains, monkey? You've
been told this many times. Clearly you need to do more homework. You
could usefully click around the wiki and find all the answers you need
to partake in this forum. Don't expect anyone here to correct you on
this point in the future. It's not our fault if you're a dumb monkey,
is it?



which is why we don't see
any subduction zones from 3.8 billion years ago. I guess I also have to
point out that one of the "prize" points that EEers make (quite
erroneously) is that there is no oceanic crust older than 250 million
years, which, of course, this paper quite easily refutes.

A few pillow lavas with sediments on them formed under water is not
"oceanic crust"


Even so, we
didn't need this evidence to prove that claim wrong. All one has to do is
visit the Blue Ridge mountains to see a huge section of 1 billion year old
oceanic crust that they claim doesn't exist.

A huge section? What's it sitting on? All the Archaean greenstones
(with pillow lavas) are sitting on granites. How is that "ocean
floor"?
