Okay, so far I've proposed that the Lonely Mountain is the eroded remnant of the intrusive igneous and hydrothermal component of an ancient arc-volcanic system. Going back to the earlier part about the Misty Mountains, we can now look at this mountain system with a slightly different view. The Misty Mountains is our currently active collisional tectonic feature. The Ered Mithrin could be made of reactivated sutures (from various accreted terranes as Forodwaith and Rhovanion converged on each other) plus erosional highs of more resistant rocks formed through earlier tectonic activities.
What I like about this model is that it doesn't require plate tectonics to be "active" everywhere all at once. Not every feature we see on earth is a result of currently active tectonic processes. Many features are the remnants of past activity. Think of them as a kind of of tectonic "fossil" that has survived simply by not being completely eroded away.
So that has me wondering: do Dwarves or Dragons use a tectonic model of economic geology to decide where they want to live?
