Re: Oceanus Borealis, Mars takes some hits but will rise again
Sorry,
Trying to throw multiple examples of ridges in specific tectonic environments on Earth does not sway the point. Just because some are submarine does naot amke all ridged terrains on Mars a palaeo ocean, just as the link with the ridged Maria on the Moon does not make them lava plains.
The ridges are contractional ridges superimposed on whatever was there before.
I have my own models and hypotheses. You may have yours, but stick to cause and effect, and logical deduction, not arguments by (weak) analogy.
