Georgie, on Earth, how do you call the features where oceanic
lithosphere is emplaced? Don't you call them ridges?
Don't you understand that the "tiger stripes" are ridges?

El moron, the lava is not extruded on the ridges. The lava is extruded
on
the rift valley floors.

No kidding!
Only a moron like you would suggest that I meant the lava or ice is
extruded ON the ridges.

Umm, your words, Floppy:

"Sounds like you deny the existence of ridges extruding ice".

When you backpedal, you usually go nowhere fast.

Look at that:

See the faults? See the ice ridges?
Isn't it evident that this moon is growing?

It will not take much time before people quit denying auxotectonics.

That must be why everybody use the expression "spreading ridges".

Anyway. Let's check your brand new position on the matter.

Do you agree that there is ice extruded by rifts (to make you more
confortable) on Enceladus? Do you understand that this ice is fresh
because it is crystalline? So where is that ice going?

No.The ice isn't extruded BY rifts. The ice is extruded AT the
rifts/fracture zones.

Since we know almost nothing about the tectonic
system at Enceladus, it would be premature to make a definitive statement
about why the ice extrudes AT the rifts. But we can look at what we know
about physics and tectonic systems overall and make some generalizations.
For instance, given the nature of the extrusions there, in the form of ice
geyser activity, and given the presence of hotspots along the tiger stripes,
it is a pretty good bet that hotspot ice volcanism (yes, I realize that term
may appear to be an oxymoron) is involved.

From the rifts... through the rifts.; whatever...

Indeed, it does appear to be an oxymoron.

It is liquid water volcanism.

Otherwise there would be no crystalline
ice. There is very likely steam that would explain the geysers of ice. A
large amount of water is constantly ejected from the moon and feeds ring
E. It is evident that this phenomenon is going on for a long time. In
addition, most of Enceladus surface is young (low cratering) with the
young floor surrounding the ridges, especially the southern pole at the
"tiger stripes". It means that the young floor was spread by the tiger
stripes. This is reminiscent to Earth's ocean floor. Of course, all that
water ejected in space or spread at the surface must come from somewhere
as the moon show no sign of depletion.

Secondly, the surface of Enceladus is full of open fractures. It implies
a tensional stress all over the surface without evidence for
compressional stress at all. It is a strong argument for an expansion of
the surface. Besides, we have similar clues from other moons like
Ganymede, Miranda, or Ariel... and from the Earth.

Of course, all that
water ejected in space or spread at the surface must come from somewhere

Umm, the temperature at the south pole of Enceladus is -220 C. The hotspots
are only 100 degrees warmer, making them -120 C. Which means that it is ice
volcanism.

The tensional stress can more easily be explained by tidal forces

which, by
the way, would also explain the hotspots, expecially considering the fact
that you can't explain why Enceladus would be expanding.

http://www.universetoday.com/2007/12/18/enceladus-cold-moon-with-a-hot-spot/

"The leading model for the cause of the plumes on Enceladus is that the moon's
tides cause its crust to ratchet, or rub back and forth, in a set of faults
near the south pole. The forces between Enceladus, the big planet Saturn and
another moon, Dione cause what's called dynamical resonance, and Enceladus
is continually squeezed under this gravity field. This process creates a
small hot spot, in relative terms, for an icy satellite."

Note that last sentence. Read it again. Now read it yet again.

George, you're boring. If there is crystalline ice, there is liquid
water. period.

The tensional stress can more easily be explained by tidal forces

Tidal forces imply both tension and compression. The compression
component is missing here. If you look at other moons, explaining the
surface of miranda as the effect of tidal forces is equal to believe in
Santa:

You're denying the evidence. Probably because you belong to the past
century. It's time to move on georgie!

The tidal hypothesis does not hold. Mimas is as big as Enceladus, it is
much closer to saturn and the excentricity of its orbit is much more
important. It should be subjected to a tidal effect that is 25 times
more important than enceladus. But despite it is also an icy moon, there
is NO visible geological activity. Its surface is heavily craterized.
