Plate tectonics
Mars quakes creating upward thrust

I think we need a ‘we think” on these

Volcanos – probably reasonable evidence for thse

Note that the “major change in the cyclic events” could be very local, such as a channel deposit. We’d have to see if those more massive (less laminated) upper strata persist laterally, or pinch out. The rover might be able to determine that, but of course it will be best to have Boots on the Ground.

I hear you.

(If you have not noticed over that time, I am primarily focused on other things :)

In reply to Cotour. Cotour: You really should read my webpage sometime. If you did, you would already know there are no plate tectonics on Mars, that volcanic activity played a large part in its geologic surface, that earthquakes do occur, and that there is plenty of surface water ice on Mars, NOW. I probably post on these subjects at least twice a day, and have been doing so for about ten years. It is too bad you had trouble finding those posts. :)

Q: And the thrust upward is do too?

* Plate tectonics? (Is there plate tectonics on Mars?)
* Volcano’s?
* Earthquakes?

All of the above?

Obviously, there was plenty of water on Mars at one time.
