Thank you for the simplified, but essential details to this matter. Personally, I have taken the theory of plate tectonics with a grain of salt, but that's beside the point. Given the various examples you've presented, mountainous regions don't necessarily need to be deep in the mainland of a continent. That alone has helped me tremendously and I appreciate it. Forgive me for continuing to pry, but do the kinds of elements, minerals, and such vary depending on the location of certain mountain ranges? Maybe the moisture levels or climates impact the kinds of mineral deposits and developments? And would external influences even have any kind of impact on the kinds of deposits found within its chasms or depths?
