Don,
The thing is that no differential rotation exists in the Earth structure
except
through exceptional circumstances, conducting to a reversing torque effect
whose evidence is available in many parts of the world.: cf Spitzberg, the
Kola peninsula etc
( I believe you have noted this in some of your publications)
Of course the causes of such could not be an Uniformism based process,
since we would see such thing in progress right now !
What is it then ?
In fact there a two main processes at work conducting to Earth relief, and
both cannot but be understood only within the UPL approach ( Universal
Pressure Law)
One lead to Earth Expansion and the transformation of heavy atoms to lighter
ones.
The second leads
a) to Orogenenesis as well as to Sills, Laccoliths spill ( soft hit by ???
.... )
b) to blue dirt ( Peridotite/Kimberlite/Serpentine) & dikes (hard hit by
meteorites)
You have been strongly criticised by Zenner, as I have noted since going
back today on past postings, this for not providing a satisfying mechanism
for Earth Expansion. This mechanism exists of course and is not relative to
the Earth only, but applies itself to any planet of our star system, as
well as to any planet of other star systems. That mechanism cannot be again
understood if not acquainted to the UPL.
The evidence you are providing on your site is superb, and should led to
interrogations on the value of present official Theories, at the very least.
.... but this is not the case unfortunately. Too many George & clones on the
sci.geo.ng at the present time... Sighhh !
Incidentally, I have found recently the answer to the global question
nagging me since years & relative to the overall orientations of Caledonian,
Hercynian & Alpine mountain ranges when comparing such to each others. Why
are Hercynian always oriented E-W and Alpine N-S ? Interesting question, Hey
?
As well why are Hercynian valleys narrower than Alpine valleys ?
I am sure than Georges and Zenner will come up with most satisfying answers
to those indeed
With best regards

Have a ball with applying a differential rotation in the mantle with
the data you provided and a rough guide for a fluid celestial object
in motion -

As a fluid in motion,the mantle is moving at 1000 mph at the Equator
and diminishing to zero at the poles and unlike a solid,if fractured
crust, there will be differentials in the form of bands generated by
the diminishing speeds depending on fluid densities in the mantle.I
assume that those who study fluid dynamics would take this as a matter
of course and not at all as an exception.
The way I see it, the closest we get to that is in the way spin has
affected the crust - a bit like the way the regular weather works in
twisting away from the equator towards the poles:-

That's in the crust of course and just in the northern hemisphere. The
southern hemisphere equivalent is in the way Australia and Antarctica
have detached from India/ Africa:-

But that's in the crust, which is solid. And actually it's not in the
crust either. It's in the way that the *DISLOCATIONS* in the crust
make it look so. The crust is passive. A chain is only as strong as
its weakest link(s) and so it's not the crust, but the suite of
dislocations that are breaking it up that's making it weak and the
pattern to look like 'weather'. But that's a bit different from the
"differential rotation bands" you're talking about, which happen in a
fluid. We're still dealing with a solid which can be stressed, even in
the mantle. Behaving *Like* a fluid (on geologically long time
scales) is not the same thing as being one (today).
Coriolis? If we like, but I don't think there's much to be gained by
pushing the analogy too far. It confuses things.
