Plus it's obvious that Mars was hit by something very, very large - so large it bulged out the solar system's tallest mountain on the other side of the planet.

You have something to back up that statement?Moose

Major Mountain Ranges - Tectonics

---

I use this context, to take a shot at whomever it was that proposed that Lake Titicaca, in the Andes Mountains, was tectonicly uplifted from sea level.As I understand it (weasel phrase for "I'm not going to supply a link"), the Andes Mountains are of volcanic origin, with tectonic uplift having little to nothing to do with their height. Of course, tectonism is the root cause of the volcanism.The volcanic rock type "andesite" got its name from the Andes.So Major Mountain Ranges - Tectonic uplift and/or volcanism.Moose

Your cited article is pretty brief, so a searched around more, and found (to my surprise) that the origins history of the Andes Mountains is much more complex than I thought, and processes that formed one part of the chain may well be very different that the processes that formed other parts of the chain. Shamefully, I fell victim to an oversimplified vision of things.I must concede, that tectonic uplift seems to be a very big part of the picture, in at least some areas of the Andes. It seems pretty hard to track down a good summary of what the relative contributions of volcanism and tectonic uplift were, in the big picture, in giving the mountains their great height. I still suspect that straight volcanism was sometimes the major component, but I may be wrong.I'll now plead "too much ignorance", and drop any further discussion of the Andes formation. I await the opinion of a real expert on the genesis of the Andes.Moose
