What type of plate boundary does a fault-block Mountain have? Plutonic Mountain? Volcanic Mountain?

Question

Also, if you know, what kind of stress each of them have.

Answer 1

Fault-block mountains are formed via near-vertical transform faulting; mountains composed of plutonic rocks (e.g. granite) result from the subduction and subsequent partial-melting of an oceanic plate beneath a continental plate, which causes magma to rise into the continent, cool forming plutons, and get exposed by uplift and erosion; volcanic mountains can result from divergent (spreading) or convergent (subducting) plate boundaries, but vary in size or composition.
