Than in peridotite? You bet!

Yeah, Frozen ketchup.

Corn syrup and silicon oil are made of a single phase.

Doesn't matter if they both behave the same way when stressed.
The analogy is bogus because in a multiphase material like ketchup, heat
transfer will be different than in an solid.

What about the rocks of the mantle, Stuart? What did you find for
them? |

You're better off picking on Einstein, you know, a dead guy.

No offence to your perspective of geodynamics based on condiments,my
analogies are drawn for observed rotational dynamics of a celestial
object in a fluid state - stellar dynamics.Although I have sworn off
this for the summer,it is remarkable to think that you are doing plate
tectonics a favor by pushing a geostationary 'convection cell'
mechanism.
Unlike other good speculative perspectives,geodynamic involvement in
geological evolution is almost certain,even that guy Florian borrowed
from my idea of the adaption of individual plates to planetary
curvature due to the less than perfectly spherical Earth ,a feature
which is due to geodynamics of differential rotation of the interior.
The worst possible outcome is that the evolution of surface features
and correlations between surface features would go into trying to
affirm a speculative mechanism like 'convection cells',a case where a
genuinely good foundation is used to build a rickety shack rather than
a palace it deserves.What is so repugnant about geodynamics to guys
who inherit thr plate tectonics concept I do not know but maybe
something will come to me by the end of the summer. |
