Yes, there is insignificant deformation relative to boundary conditions. We
agree on that, as has been stated many times. But to say that they are

Give me a break. You don't know what is a fact. The fact is that there
is no significant deformation that would support large displacement.

The assumption that large displacement is equivalent to "significant
deformation"
is wrong. Until you learn the difference between *displacement* and
*strain*, you
should refrain from mentioning either.

(Clever Dick. What kind of strain are you talking about here?
Heterogeneous or homogeneous?)


Does it matter? I'm talking about the relationship between
displacement
and strain in general.

Hey, Stuart, .. I think you mean
'translation' *of* the body, not displacement *within* it - if you
want to get picky that is .

Flo is using those terms interchangeably.


Though of course it's a question of
scale.

You mean the length scale over which the displacement occurs.

And EE (i.e., Everybody Else) knows what Florian's talking
about. How come not you?

Sorry, its not clear he understands it. He has repeated this several
times
and has been corrected several times.

Stuart

To put it another way, he's using the language of Plate Tectonics
itself, which is sloppy about the difference - as you say "does it
matter". Of course it matters - as Florian well knows and keeps
saying:- the **LANGUAGE** of Plate Tectonics "...is entirely that of
translational movement of lithospheric plates from 'A' to 'B', in
which the plates bodily move, ..boundaries and all, ...not the
convective cycling of a lithospheric shell according to the
requirements of Plate Tectonics."

It's about time *Plate Tectonics* recognised the difference in its own
concept, and stopped playing loose with words. Words mean what they
mean, they are not according to Alice - (or Stuart Weinstein)
.
