Do you understand the physics behind intraplate volcanism , Malcolm??

Do we have direct evidence of this existing on Mars?

Very similar processes have occurred on Mars.

How do we *know* this? It is assumed.

Just because Mars shows no sign of plate tectonics now, doesn't mean it never had it in the past. Venus, now, shows no sign of plate tectonics.

So given that both Venus and Mars show very little, if no, plate tectonics activity it is just an assumption that these plate tectonic processes existed?
With very much respect, I do not see direct evidence here to rule out the EU hypothesis.
Contrary, EU seems able to explain these features *without* the tectonic activity that may or may not have occurred in the distant currently unverifiable past.
Yes the hypothesis is different, as we look to explore Mars we should examine the testable differences in hypothesis to make falsifying predictions. Carl your knowledge of current terrestrial (mainstream) geology can no doubt help us explore these.
Something like EU expects this... MS does not... MS expects this... EU does not... etc... ?
